BISSELL® Big Green® PET PRO Carpet Cleaner, 3288

I started out using this machine because I was in a pinch when our carpet vendor had to cancel. My first experience was with a rental from a local hardware company, per the recommendation of our rep. The rental had clearly been used a lot, and not well cared for. I was skeptical. However, our $5000.00 commercial machine was heavy, hard to fill, rigorous to use, exhausting to use solo, and an inconvenience for those occupying apartments. With this machine, I was able to complete the job in a fraction of the time, had no interference with other occupants, had no fatigue, and the end result was a much cleaner and sanitary carpet. I was so pleased I bought 4. I have since bought nothing but this. The upholstery attachments work well for furniture and tight spaces. The stair tool sees no loss of suction. The machine is simple to use, can be used by a single person with ease. The suction is less than more expensive machines, but the scrubbing bristles penetrate deep into the carpet and in my opinion yield a better clean. The capacity is small, but that can be seen as a benefit. This is not a machine for water extraction, but for cleaning. The machine is easy to clean, and upon first use it will be evident how much this machine really pulls out of the carpet. There is a clear channel on the top of the collection bin and you will be able to see the hair, dirt, and grime as it is extracted. There is a multi color pinwheel on the top of the machine for flow, that will let you when when water is flowing or the tank is empty. For areas with pets, it does extremely well with hair and dander. Rather than flood and suck, this machine will excel with proper chemical treatment. Pre-treat stains properly ahead of time, and mix the proper fragrance and general carpet cleaning solution for your needs with the clean water tank for optimal performance. It’s a prefect option for single households. For commercial, I recently chose to use this product over a much more expensive machine. A larger complex with indoor, carpet hallways. Roughly 2 linear miles (4 buildings, 4 floors per building) and 6 foot wide. To make it work I prefilled a 30 gallon tote with water and treatment, and one empty tote. I was then able to fill the tank when needed, as well as empty the collection tank with ease. Pretreated the stains with a backpack sprayer, and the end result was great. My legs and back are still thankful. One caveat is that it is still pretty loud.

I’ve wanted this carpet cleaner for a some time, but didn’t want to spend the money. Well we finally gave in and bought it. My only mistake less NOT purchasing this years ago. I cleaned half the carpets in the house yesterday and they look and feel so soft and clean. I will finish the rest of the house today. The machine is quite heavy, but I like that and it does not deter me. The suction power is an A++ and they took no time to dry. Sincerely, A Happy Customer

I am a 3 fur baby owner with a carpeted living room stairs and hallway. In the process of buying this home. Until the papers are signed, I need to have a clean carpet!! Having 3 dogs, accidents happen. I was using the Bissell petpro steam cleaner. I have been using them (yes them- I own 3). Using these machines 3 sometimes 4 times a week. Having a living room over 600 sq feet.. it was worth $$. They all worked well. I needed something to work AMZING!!! this is the AMAZING machine!! The carpet is almost immediately dry, or damp. It is my new go to!! ! I was worried about weight but it rolls pretty easy Large tank is a big plus! I would highly recommend, and while not the cheapest carpet cleaner out there, I find it basically works like a professional. Thank you Bissell!!!

This was my first carpet and upholstery cleaner purchase. We have mostly tile flooring in our home with carpet in the bedrooms, so I never considered getting a carpet cleaner when we moved in. However, when I started dog sitting for people, I had to reconsider my decision. My home smelled like dogs no matter how often I cleaned and I was tired of it, so I began my search for a good quality carpet/upholstery cleaner. I almost purchase a Hoover steamvac but I was really concerned about the durability of that product. I honestly didnt think it would last very long with frequent use. When I read all the amazing reviews for the BISSELL Big Green I contemplated it for a while before actually making the purchase. I really didnt want to spend so much money but it looked incredibly durable and I wanted something that would last for a good while and work as advertised. Let me say, this product did not disappoint! Ive used big green for a large area rug in my living room, my couches, the carpet in my bedroom, and the upholstery and carpeting in my husbands car. Every time, I was amazed with how much water, dirt and sediment the big green pulled up. What it did for my husbands car (with the hand tool) was especially impressive. We are taking an 8hr road trip with our son and I didnt want to be confined to a filthy car for such a long period of time, so I took it upon myself to give it a deep clean. We have owned this car for 2yrs and have never had it cleaned other than removing the trash and vacuuming it out. The people that owned it before us didnt bother getting cleaned before selling it, so when we purchased it there was also some staining and tons of dog fur. Now most of the dog fur had been long gone before I used the big green, so please keep that in mind. I cleaned all of the seats, top to bottom and then made my way to the carpeting, cleaning underneath the seats to the best of my ability. I probably went over the seats about 3 times before deciding that I was finished for the day. Now, when I went to dump out the water, it was black and there was lots of mud/dirt and rocks at the bottom of the dirty water container. There were even some small clumps of dog fur floating around in there. The interior of the car doesnt look brand new by any means (I will probably need to get a professional detailing service for that) but I am no longer disgusted at the thought of a long road trip in it. It actually smells pretty clean now and looks presentable. So, here are some things I love about the big green: It is an incredibly simple machine. Without the hose attachment, there are only 5 parts including the portion containing the motor. There are two bins, one for dirty water and one for clean, a clear dome shaped lid with a handle to cover the dirty water container, a small plastic, square filter type thing that you dont really need to bother with and then of course, the body, which contains the motor and scrub brushes at the bottom. Literally, all you need to do is add your water and cleaner, stack the bins on top of the body, plug in and turn on and you are ready to clean your carpets. The hose/hand tool attachment is also very easy to use and adds two extra parts. Not too many things to get broken here. The plastic is also very durable (as Ive mentioned before) and seems like itll last for several years. The suction is very strong and easily pulls up embedded dirt and small rocks from your carpet. Even while using the hose and hand tool, it didnt seem like any of the suction was lost. And of course, b/c of the great suction, dry time is minimal. Id say a couple of hrs for carpeting and upholstery, although when I used this to clean my couches, I gave them until overnight before I sat on them. It took the car about 4hrs to dry completely. Regardless of how long the dry time is, this isnt going to leave anything soaking wet. It will be only slightly damp once the water is sucked up. There are a few small things I didnt like about the machine. It is very difficult to maneuver (which was expected). When cleaning carpets, it does tend to spit out clumps of all the stuff it just sucked up. You know its working when you see these gross clumps but they are still annoying to pick up, unless you have someone going behind you to do it. I wish the hand tool had spinning bristles, although Ive heard that you can purchase one for a reasonable price. The last thing I didnt like was that this seemed to be a little too aggressive for my large living room area rug. Its a wool rug and it just seems like there are a lot of extra fibers getting sucked up by the machine, although the spinning bristles fluff my rug back up nicely. I may need to switch to using the hand tool on the rug though, in order to help prolong the life of it. All in all, this is a great product and well worth the money that was spent on it. It is expensive but I do believe that, in most cases, you get what you pay for. You wont regret buying this carpet/upholstery cleaner!

Ive had these carpets for 17 years, but they are not in bad shape. Cats and children have taken their toll, but theyre still holding up. I have a Dyson Animal vacuum which removes large amounts of cat hair and my girls might lose more hair than the cats given how often I have to cut it out of the beater bar of the vacuum. A few points of note for this review. Ive only had the unit for one day and can not speak to the durability of the unit, but I can say that it feels solid and does a tremendous job cleaning carpets. Im also upgrading from a cheap carpet shampooer which now falls into the toy category. I started off by thoroughly vacuuming the carpets with the Dyson vacuum, removing bits of fuzz, cat hair, stuff like that. Then I loaded up the machine with hot water and the contents of one of the provided bottles, and went to town. It took me a few minutes to get the hang of maneuvering the machine, but I definitely got into a rhythm. It was hard to keep it slow as I wanted to see the results, but I was patient and kept going until the flow meter stopped spinning and I was out of water. I dumped the dirty water bin slowly into the toilet and I swear to God it looked like used motor oil coming out of there. These were carpets which were vacuumed weekly and shampooed a few times a year. Motor. Oil. Clumps of cat hair which must have been woven into the carpet fibers and held in too tightly for the Dyson poured out with the water. I ran out of time last night and was unable to test the hose attachment. This is needed for areas along the edges of the room since the shampooer cant reach that far. Pros: * Cleans very well * Its a good workout * The transformation is mesmerizing * Its heavy, so it is able to clean deeply by pressing on the carpet * Youll strike oil, right in your own living room! * Gave my carpets a few more years of life * The rooms smell better, but that might be the fragrance of the shampoo * It came with three small bottles of cleaner to get you started Cons: * $$$$, although cheaper than professional service in the long run * You will realize how disgusting carpet can be and consider replacing it with laminate, LVP, or hardwood * Its heavy, and cumbersome to carry up stairs * Supposedly the flow meters crack, but they are not expensive and are easy to replace * Why was there motor oil trapped in my carpet? * Its big and bulky, so storage can be tough even though the unit folds up

When it came time to do the Spring Cleaning this year, I decided to purchase a new carpet cleaner. The Hoover Platinum had served me well, but keeping the machine clean was a pain, it left the carpets pretty wet and the resulting shampoo residue led to the carpet getting dirty much quicker. When I started researching new cleaners, the Bissell quickly rose to the top of the list. The primary reasons were the simple, easy to clean design, powerful motors and all of the excellent reviews from fellow shoppers at Amazon and across many sites on the Internet. I was not disappointed. The cleaner arrives in a large box, fully assembled. This model also includes an upholstery tool with a pretty long hose. Other than removing a few pieces of cardboard from the base and inside the dirty water tank, it comes ready to go. I love the overall design of the unit. It is manufactured of rubbermaid-like plastic that looks like it will hold up fine. Unlike other consumer cleaners, such as the Hoover Platinum, there are not a bunch of fancy lights and other bells and whistles on this one. It is simply the base cleaner, a clean water tank, dirty water tank and top that directs dirty water into the tank. The power cord is 25-feet long, enough for a large room without going back and forth to the wall to disconnect and reconnect it to other outlets. The machine is ugly when compared to the fancier consumer models, but I cared much less about that than how it worked and the simple design that makes it ugly also lets it work well and be easy to maintain. Using the unit could not be much simpler. Fill the water (bottom) tank with hot water from the faucet and the right amount of cleaner (water tank cap is also a measuring cup), re-attach the dirty water tank on top and you are ready to go. This unit dispenses water and cleaner while moving both forward and backward if the button on the right handle is depressed. The instructions advise you to make a forward and backward pass while dispensing water and a without pressing the button to suck up excess water and heat dry the floor. I followed the instructions, but made a second dry pass just to get the carpet as dry as possible...Im not at all convinced that second pass made a difference and it is absolutely not required. In my experience, the water tank is adequate to clean about 80-90 square feet of carpet, depending on the number of passes you make and how much you overlap. With a single pass and a 2 inch overlap, I got about 90 square feet between fills. Having used 5 or so different carpet cleaners from Bissell and Hoover, at all ranges of pricing, I am very impressed with the Big Green. It did a great job cleaning the carpet. Its strong suction led to the carpets being dryer after cleaning than any until I have ever used or seen used, rental and professional cleaners included. In fact, during the cleaning, the Bissell was regularly deposing small balls of hair and fur that 4 passed with my Dyson did not get out of the floor and the Dyson has excellent suction. The carpets took about 2 hours to dry in a 68 degree Fahrenheit room with the ceiling fan circulating air and the windows open. The Bissell also cleaned up several stains in the carpet that were left by my Hoover. That said, I am also using a new cleaner, the Bissell Pro brand so it is hard to say if that is due to the shampoo or the machine. There is a handy flow meter than is directly driven by water flowing past that lets you see when the tanks are empty or if there is still water in the carpet that needs extracting. This unit is heavy and bulky. It is not much heavier than my Hoover Platinum, but the extra bulk of the design makes it harder to carry up stairs. Doable but folks with less upper body strength might need help. Emptying the Bissell is easy. Pull the black handle on the cover forward, remove the cover (I tilted it off from the back to keep from dripping on the floor) and then carry the tank to the toilet for a dump. One thing to note here is that a significant portion of the top of the dirty water tank is exposed. While the water level in there is 1 1/2 or so from the top after using a full water tank, those who are balance challenged may want to push the machine close to where they plan to dump to avoid spilling on the way. After dumping the dirty water, it is a good time to fill the clean since it is on the base of the machine below the other tank. This process is simple as well. Lift the handle and pull the tank up from the machine, open the lid and use it to measure the amount of shampoo to add then fill the tank to the line, which is basically a completely full tank. One thing I appreciated is that water does not drip when the tank is removed, even though water is drawn from a valve at the bottom of the tank. The only downside to the design of this tank is that the bottom is not at all flat, so you cant just sit it in the sink and get a full tank. Not a big deal, but some may find it the weight of a full tank a little hard to hold below the faucet. The Upholstery nozzle and host is nothing special as far as design goes, but the suction from the Bissell motor lets it work like a champ. I used it to clean carpets and it worked very well. Would be nice if there was a way to mount it to the machine but the design does not allow that and it is something I am willing to deal with. Cleaning the unit when done is a snap. Rinse out the tanks and the top cover and then use a towel to wipe it all dry. The handle folds down to minimize the space this takes, but it is a bigger unit so plan on dedicating a spot for it. Overall, this gets a strong recommendation from me. Its roots as a commercial rental machine help this shine in the home. The design is simple and easy to learn to use. There are not a lot of bells and whistles to break down...the only indicator is a simple flow meter not some fancy electronic gadget. And it works and works very well. Exactly what you would expect if you shelled out $50+ dollars to rent one.

Firstly, I have to say that I am -was- a huge fan of the Rug Doctor. Weve rented the Rug Doctor many times over the course of a few years after out carpet cleaning machine died. We did like the Rug Doctor, but when you add up the costs associated with it, $25-30 base rental + $7 for the hose, as well as the cost associated with running to the store to get it and return it, let alone the hazards associated with the last people who rented it and didnt clean it when they were done (pet hair EVERYWHERE). Either way, we certainly thought the Rug Doctor was good until we purchased this Bissell. As others have mentioned, it picks up to much more water and leaves your carpets much drier right after going over them. Its been about a year since we rented the Rug Doctor. We went over the carpets in one direction and just for kicks we went over it in the other direction (vertical and horizontal). We got so much more dirt out of our carpets than we would have ever gotten with the Rug Doctor! It was just as much gross as it was amazing! This Bissell Big Green is very easy to use and comes with everything you need to get going, including 2 small bottles of solution and a sizable hose for spot cleaning. I would HIGHLY suggest you purchase additional solution (I used the Bissell Deep Clean-dark blue bottle) if you have more than 1-2 rooms to do that have really dirty carpet. I did three moderately sized rooms and had to refill 5 times. This may seem like a lot, but I went over everything twice or even three times in high traffic areas. Even with the extra passes, the carpets were dry very quickly. After the carpet completely dried, the carpets look amazing! Before they were starting to look different colors across the carpets, and now they look uniform again. The carpets are soft, correctly colored, and vibrant. There even is a nice sheen to the carpet. I do think it pullet the carpet back up where it was more pushed down from excessive traffic because it looks better than it has in years! I do have two of my three rooms on a second story and had to move the carpet cleaner up the stairs. The machine is heavy! I took off the dirty and clean water tanks so you basically only have the machine itself and it was a slight bit heavy to haul up the stairs. I dont know if it would be doable for everyone without assistance. For the three rooms, it took 5 refills of water/solution and about three hours. Make sure you do read the directions! I was not holding the dispense button enough, which did cause for a little extra time because I redid that area. You are supposed to move forward holding the button and then move backward over the same area still holding the button in a slow manner to allow the spinning brush to do its job. Then release the button and go forward and backward to get the excess water sucked up. Reading the directions first will surely help cut down your time. Overall, if you are on the fence about purchasing this machine, just do it! I thought about it for a few hours and ended up just purchasing it. When you consider how much it costs over time to rent a not so great machine (now that I see how much better you can get with this machine) and time time and effort required to go get it and take it back, as well as the convenience of having your own machine if you need a quick cleanup, its totally worth the cost. I would HIGHLY recommend this carpet cleaner, it really DEEP DEEP cleans! Fair warning: I have only had this machine for about a week and used it once. I was just so amazed that I couldnt wait to write a review. If I do run into anything, I will be sure to update this review.

Ive tried a variety of carpet cleaning machines. I dread carpet/rug cleaning!!!! I finally decided I needed to invest in something that worked WELL so got this machine. Wow it works!!! Even on a shag rug. The key I think is to pretreat any very dirty areas with the solution (dilute in a spray bottle or even in a hand held compression spray container...the kind you mix fertilize/weed killer in). If the solution can sit on the carpet/rug even for 10min it makes a big difference in how clean the carpet/rug will get. Then use the cleaning machine. It takes a few passes but it gets it clean. Take a bit of time going over the area several times if you want it almost dry. I cleaned a shag rug a few hours before I had company and it was clean and dry in a very short period of time. I went over the rug very well with just suction and it was almost completely dry. To get the last bit of perfect cleaning... Do a final clean with just hot water in the machine. Leaves the carpet/rug soft with no cleaning residue left in the carpet/rug.

I would have given this a five star review had it not been for the lame directions. With the exception of one wall to wall carpet in my bedroom, the rest of my rugs are rooms sized rugs and I have two dogs - one of which is old and has become incontinent. I have previously rented a rug shampooer from Lowes and after I buy the cleaner it usually costs over $80. After you pay to rent the machine, you still have the hassle of loading in your truck and then have to get it back on time not to mention you dont know what kind of filth it has been used on prior to you using it. As it turns out, the Big Green Machine is the exact same machine I have been renting. At the cost of $400 it more than pays for itself after four uses. Plus, I dont have to spot clean accidents and cringe between rentals thinking about the residual germs and dirt I wasnt able to get up. It really does do a fantastic job. I cannot stress the importance of vacuuming your rug immediately before you use it. I vacuumed my living room rug right before I used it but the bedroom rug had been vacuumed a couple of days earlier so I tried to cut corners and it was a mistake. The hair I couldnt see would collect into nasty wet globs and interfere with the suction of the machine. Even the rug I had vacuumed immediately before shampooing still had hair on it the shampooer pulled up but didnt interfere with its operation. It just goes to show how powerful the cleaning is. But as to the directions.... Since I had used the same machine several times before I was already familiar with the basics. The manual that came with the machine was limited (10 pages) in information. You would think for $400 you would get a little more detailed info. Just about everything I have ever brought will give you bold instructions on what you need to do before you use it the first time. This did but it was only safety instructions to keep from getting electrocuted or injured. The box said it included three trial size bottles of cleaner but I couldnt find them. Instead there was a random piece of packing cardboard in a plastic bag (picture attached) by itself so I assumed it was a factory mistake and that the bottles of cleaner were supposed to have been in that bag. I followed the directions in order and filled the tank with water and cleaning solution, put it on the machine and then put on the dirty water tank as it said on page 4. Page 5 told how to clean your carpet and gave tips. The first tip was to remove the cardboard cutout from the foot. I looked down and saw a little piece of cardboard sticking out from the foot area and pulled it and it came off. My thought process was it must be a small piece of cardboard since it wasnt mentioned in the directions until after it tells you how to fill the tank and put it together to start using and it, plus you cant turn the machine on its side after you fill the tank and, again, it was only mentioned as a TIP. So, after removing the cardboard I started cleaning my rug but after a while I looked at the dirty water tank and the amount of water in the tank didnt seem appropriate to the amount of solution I was applying. I continued to go over and over the rug trying to suck up water and after a good while stopped and looked up troubleshooting. It said check the rollers so I removed the tanks and turned the unit on it side and there was my problem - a LARGE piece of cardboard that stretched from one end of the base of the machine to the other. I would hardly call getting that thing out of there a TIP - It should have been clearly stated as BEFORE USING OR FILLING THE TANK BE SURE TO REMOVE THE BIG A*# PIECE OF CARDBOARD FROM THE FOOT OF THE MACHINE. But at least I had found out the problem and was now able to suck up dirty water. The dirty water tank filled and now it was time to go outside and empty the dirty water. Imagine my amazement - and embarrassment (neighbors were walking by) - when I poured out the water and out came the three bottles of cleaner AND a huge piece of cardboard. I definitely looked like the proverbial dumb blonde. It wasnt until later when I looked at the Whats in the box section that I saw the very last thing mentioned was the cleaner was in the dirty water tank. Who would have thought?! I had made the mistake of looking at the outside of the box to see what was in it and never bothered to look at that part of the manual. Plus, the manual showed pictures of what was inside the box and since I glanced over the pictures, I didnt think I needed to read a description of the very last thing mentioned which was the three bottles of cleaner. My advice to Bissell would to please change your manual and include: BEFORE YOU USE FOR THE FIRST TIME! 1. Turn the unit on its side and remove the large piece of cardboard from the foot of the machine. 2. Open the dirty water tank and remove the three small trial size bottles of cleaner and the large piece of cardboard from the tank. Like I said earlier, the machine works great but I could have been saved a lot of time and aggravation had those two small but important steps been included prominently as BEFORE YOU START items in the manual. But the machine does work great!

The most important adjetive for this machine is, AMAZING! First, Id like to recommend anyone researching this or any product... Read reviews. The good and the bad! Then, look for the trends in those reviews and from there, determine for YOU what is important versus what is not important. A handful of bad reviews that involve complaining about things that have nothing to do with the product specifically (i.e. packaging, delivery, etc) or a small percentage of reviews that have minor breaks or other minor problems versus the hundreds or better yet, thousands of great reviews on the same product, those bad reviews may need to be taken lightly. Unless, of course, those things are important to you. Do consider this. It doesnt matter how a product is made (assembly line or hand made), there will ALWAYS be faults. No matter the company or how good the product is overall. Obviously, the fewer problems the better but if you are seeing hundreds or thousands of good reviews to a few dozen or so negative, then that would be a reasonable percentage of errors with any good to great product. I know some people will have multiple bad experiences with the same product where others have no issues. There are a multitude of reasons that could happen but look for the overall, not just that one review. That said, I recommend and do this myself, but when looking for trends, if the bad reviews are all because something breaks but maybe its a different piece each time, then there may be an obvious trend. I would possibly take that into consideration. It may not make my decision for me, but the trend of what users say about the product is what Im looking for and its paid off for me quite well. Bottom line of what Im trying to say is, dont just look at one or two reviews and dont just look at the good or the bad, but rather review as best as you are comfortable with on both ends of the spectrum and decide what trends you find and how those trends impact your decisions. For me, reading actual buyers/users reviews are better in almost all circumstances then any lab testing or any company that does product reviewing. With that, I have started my research with company reviews, but in the end, WERE the end user! It is our perspective and experience that matters most. Id rather gain real world end user perspective then read an article that may or may not be paid for to make a statement one way or the other. On to my review. I have to say this first. When I was researching and reading reviews, my first thought, when I decided I was gonna make this purchase, was I hope my money doesnt go to waste, but if I get even one great cleaning, that is better than I could pay any over priced professional with a oversized vaccum in their van, that doesnt even lift out the dirt but just wets the floor and kinda cleans. Then ITS WORTH IT. I mean not to offended any professional out there but simple soaping the floor and suctioning it up isnt cleaning. Thats multiple experiences and eventually, history doesnt lie. Now, I did follow the recommendation of at least one reviewer in this review group that doubled up on the solution, and it worked. Im not recommending that for you. Just telling you my experience and what worked for me. Now I know you saw the pictures and probably felt ill just looking at that floor. Obviously, we thought so too. Its disgusting and thus we purchased the Big Green Machine. We can compare this unit to the many other ways weve tried to keep carpet clean in companies paid and products purchased and nothing else has come close to this. We have SEVERAL pets to which I wont mention how many but I will say I dont have enough fingers to count them all. We love our fur babies and other pets. We also like having a clean floor and clean house. The floor is the biggest battle in our household. Nothing is more off putting then walking into someones house and it wreaks of animal urine. But when its your own home and everytime you come home it smells. YUCK! Multiply that smell by 5 and and that is what anyone else coming into your home smells. Weve been there. We were just there. We didnt want to host anything because of the floors. But now, I can very happily and more than confidently say that weve found our cure. This machine is just straight up, Amazing. Ive never had a professional even come close to cleaning carpets as well as this BIG Green does. If I could find a professional to do this it would almost absolutely cost more than this machine, but I can get multiple uses out of this, as long as well cared for. You can see it for yourself in my posted pics. That dirty floor there is several months of pet stains because the moment we moved into this house my first dog discovered the location of the previous tenants dogs place within less than 5 minutes being in this home. We even waited outside with our dogs before going in to this house for the first time, while they all did their business and still she started this disgusting trend. So lets chalk it up to this. More than a handful of household free roaming pets and 11, thats right, ELEVEN months of this. So heres what we did. Machine arrived as quoted at time of purchase. That very next available day off, Saturday, I carefully went through the included manual and honestly, this machine looks like it could or should be difficult, but it truly isnt. Very easy to unpack, assemble, dis-assemble, and re-assemble again. Thats important as you will have to empty this unit and refill with clean solution every one gallon. VERY easy to push/pull. Dont leave solution in tank or in machine. Keep all parts clean and dry when in storage. Thats how Ive best kept any product that uses liquids with electrical devices. Never store liquids in the machine or attachments when not in use. Unfortunately sometimes that means tossing any leftover portions unless you wish to find another way to store the liquid. Diluted solution is not recommended to be put back in with concentrate as number one, it likely wont fit, and number two, youll ruin the concentration level of the original solvent. Next, I went to work on the floor. Now, I do have to say many people and these products suggest to pretreat. I did NOT pretreat. I wanted to see how this product (with double amount solution) would actually hold up. I started with a small space (4 x 4 landing) and immediately could see the difference. Then when I started the first trip down the hallway, my wife suggested to take before and after photos. Thats what you find above. My process with doing this was to make a forward pass (I divided the hallway into 3 sections. Moving side to side the up. Closest, middle, furthest). While moving forward, I moved the machine steady at about 1 inch a second or slower. I know that seems slow but look at it. It works well. Then on the backwards pass/pull, I moved at the same pace where the carpet was heavily soiled, but where it wasnt pet stained I went about 3 inches per second. This may sound slow but consider that you have to let the solution get into the carpet and let the machine do its job. No product can do that if you rush through it. And dont force it. Let it do it job. You just steer it and place solution accordingly. On the forward pass, I held the trigger to spray the entire distance, then on the backwards pull I only held the trigger where stains resided. The suction is at the very front of the unit and collects everything on the backwards pull. Where heavy solution was applied, another slow pass, without pulling the trigger, will gather up about 95% of the moisture. That said I did make 2-3 passes forward and back with applying solution where the stains were prominent. Which was a strong majority of the hallway. The first pass really did the job better then great but considering the nature of the stains, I wanted to be more than thorough. This hallway measures about 4 wide by 23 long and took about 1 to 1 1/2 hours. But, boy was it worth the time, money, and effort. The bedroom is my young daughters who struggles still with door knobs and thus her room is open for her, by which the pets in the house took full advantage. Still not good but they did keep most of there spotting to the hall way. Her room was just as, if not more important than the hallway to get cleaned for her benefit and sanitary health. Once I was done with the cleaning process, I emptied the dirty and clean water tanks and rinsed thoroughly. Then I put about 1/2 gallon of plain water (No solution) in the fresh water tank and ran that over the clean floor by spraying the water just as if I were cleaning the floor. I didnt use the full half gallon. I ran enough water through until I felt the solution was pretty well cleaned out. Probably a total of 1-2 minutes of total trigger squeeze. This was to allow fresh water to run through the machine to clear out the solvents in the lines that carry the solution from the clean tank to the sprayer nozzle. I cant confirm this was or was not long enough. Just going on experience to avoid damage of the unit while in storage. Once that was all done. The carpet was completely dry by the time we went to bed. So probably 4 hours or less. Its been 2 days since I did this and spots have NOT magically returned. This is a major win. I will try to update this post after a total 1 week has passed to see if it still holds. If so, Id call this an absolute winner, where other products have completed the job or professionals have left and within two days spots have returned. That has not yet occurred in this case. Also, to resolve the pet issue, we placed a very solid metal baby gate to block the dogs from going back upstairs without us, during the day, until its all our bed time. We work from home, so the dogs hang with us throughout the day. They sleep. We work. They have always and continue to go out at least 8 or more times daily or whenever they sit at the door and whine. Love em, but now we can live easier without never disappearing pet stains. Weve been renting in this house for almost a year and in our previous home we sold, we had hard floor, for a reason, and will do the same when we buy again in the next 6 months or less. Clean floor + landlord = No loss. Happy research hunting and good luck with your floors.
