iRobot Roomba i4+ EVO (4552) Robot Vacuum with Automatic Dirt Disposal - Empties Itself for up to 60 Days, Wi-Fi Connected Mapping, Compatible with Alexa, Ideal for Pet Hair, Carpets

I bought this Roomba i4+ because Amazon was having a sale and I was curious if it would freak out my dog. When it arrived, I set it up according to the very simple instructions contained in a booklet included in the box. The instructions may have been a bit too simple, though, because they neglected to explain - for example - that Roomba cant connect to 5Ghz wifi networks. They wait to let the mobile app tell you that after the robot has failed to connect to wifi three or four times and you finally click on the (tiny) Help Me icon at the bottom of the screen. Anyway I finally got it set up, but for $400 it was not nearly as smooth a process as it should be. Once everything was finally working, I pushed the button in the app to make the little robot go clean my apartment. It rolled off the charging deck with a cute little chirp, looked around for a moment, and then made a beeline directly for my fireplace. The fireplace is closed off by a cover, but the floor around it is lower than the floor in the rest of the room. The Roomba app assured me that this would not be a problem, because Roomba can handle slight elevation changes like that. Well, maybe some Roombas can handle it, but my little guy could not. It threw itself into the fireplace and immediately got stuck there, whirring around in noisy little circles for approximately fifteen minutes until it finally gave up and sent a notification to my app that it needed help. I picked it up and repositioned it away from the fireplace. It thanked me with another happy little chirp and whirled around it what I took to be a little dance of joy at its newfound freedom. Then it turned and threw itself directly back into the fireplace. It did this six more times. Finally, I wised up and put a bunch of heavy objects around the fireplace so it would not be able to get back in there (despite several of its best efforts). The Roomba then decided to clean under my coffee table. Finally, it was working as intended! But then I got a notification that, with less than a quarter of the room vacuumed, my Roomba was done. It was returning to its charging station. Only instead of returning to its charging station, it repeatedly slammed itself into a wall approximately six feet away from its charging station. I assumed it would eventually figure out it was in the wrong place, and I let it do its thing while I went into another room. When I came back an hour later, it was powered down in more or less the same place, apparently having died in the middle of an effort to climb up the wall itself. I put it back on flat ground, turned it back on (the battery wasnt dead after all - not even close, actually), and watched as it tried again. It did a 180, went to the exact opposite side of the room, did a few circles, and then finally seemed to figure out where it was. It then, at long last, returned to its charging station, having successfully cleaned perhaps 25% of my small living room. It was all kind of funny to watch, and Ill probably use it again just for laughs. But as a cleaning product it is definitely not worth $400. Oh, and also - the dog didnt show any interest in it at all.

The Roomba i4 (4552) model is a great time saver. I give a 4 on battery life only because it has to recharge during the cleaning. However, since it works automatically, it is not an issue. My floor has a lot of obstacles which causes the Roomba to have navigation problems because it bumps into chair and table legs. If you have a lot of open space the machine will be very effective and get the job done quicker. This is a great machine that cleans well. Yes, it is loud when emptying the dirt. That is not a problem, though- it is automatic! I purchased it during an Amazon Prime Day sale and got a great deal of $399.00. If you have a floor with open spaces it will work very well and quickly. If you have lots of obstacles, it will take longer to complete the job and you may have to reset it. Overall, it is a good buy.

My first one stopped working, but they replaced it and ever since is working better then i thought-it would. The first one Sometimes id find it jammed up , or it was trying to eat cords or rugs up or flipped over. So far nothing like has happened.

The roomba itself is great. Cleans beautifully but the base never worked. Called customer service after 2 hours talking she said I needed a new base but I got a new collection bin that goes on the roomba. I put it on anyway and it didnt fix anything. So I called a couple more times and kept getting disconnected on so I just bought a new base and it works great so finally after a year I got to hear it empty itself. Ive even changed the vacuum bag because it was full of dog hair which was why I got it. Cost me a couple hundred more but now it works great I just wish they would have listened to me and now I dont know what to do worth the base that never worked.

Love the Roombas. I have the more expensive i9 but bought the i4 for another floor. I wish it had the mapping of the i9 so I can do small areas and not the whole floor. Other than that feature, it is great cleaning up dog hair and other debris from carpets and hardwood floors. I have 4 which run every day and do a great job. They are a little noisy on hardwoods.

Have had i4 for a month and am disappointed. On the plus side, it does pick up good and the self-empty feature works good. on the down side, the i4 (basically the same as i3) is random in its vacuuming process. The model is not able to use smart mapping, which is a feature I discovered is available on newer i7 and up models. Smart mapping is really needed on a smart iRobot type vacuum and I wish I knew this before I purchased. I contacted support via email, which took a week to respond, which then confirmed, too bad, your model doesnt have the latest feature and we cant upgrade the firmware Ill keep using it, since it does vacuum, but I am disappointed with the poor programing and features of the i4.

Having a breed that sheds daily, this product has been a lifesaver. I no longer have to worry about vacuuming three times a day, knowing that the roomba will take care of it highly recommend, if you have pets.

Overall this is an excellent product. I can set it do work while Im away from home. Its quieter than my stand up vacuum and can get to hard to reach places like under my fireplace bench. It does have mapping just not the smart mapping that all the other reviews said it as missing. You have the option to join beta testing through the app so who knows maybe itll be added one day. Pros: Self-emptying and charging picks-up pet hair and dirt motivates me to clean where is robot cant go (like my stairs) scheduled cleanings easily done through the app teamwork-I can focus on other areas of my house to clean while to robot is working Cons: Culture of waste created by the company to make profit. The replaceable parts are purposely not meant to last. I can already see that the brushes will need to be replaced in 6 months or less. (Ive had this robot for about a week) Dust bags are disposable not reusable for the i4 Considering all the replacement part youll have to buy over the life time of the product the price point is too high.

I bought this vacuum at a Black Friday price. I was skeptical when I first put it into service. It got stuck in several places in my home, but after I blocked those places the vacuum has performed very well. My home is about 2,200 square feet with a mix of tile, vinyl plank, and carpet and the vacuum handles them all well. Im glad I bought the i4 with the larger battery as the vacuum has to stop to recharge about halfway through the job, which takes about 4-4.5 hours. The cell phone app makes it easy to setup and control the vacuum, plus you can see the cleaning history including maps of each job. The edges of rugs sometimes turn up and cause the vacuum to turn in another direction, but it gets covered in another pass of the vacuum. Cleaning power is good overall, hair and larger pieces dont seem to bother it much. Overall, very pleased with my purchase!

I purchased this and then returned it. The noise level was so loud that my kids woke up from it.... The suction wasnt great and therefore lots of dirt stayed left over since the brush kept on pushing it away in places it already passed.. and it kept on running back to the base for charging. My house isnt so big.... So instead of having to pick everything up and putting the chairs on the table to make place for the vacuum cleaner, I just bought a regular hand held which takes a few minutes instead of a few hours and my house is cleaner!
