Shark AV911S EZ Robot Vacuum with Self-Empty Base, Bagless, Row-by-Row Cleaning, Perfect for Pet Hair, Compatible with Alexa, Wi-Fi, Gray

I am rating this vacuum based off of what id expect from a robot vacuum. First- this is a robot vacuum and cant replace a good, regular, stand up, more powerful vacuum cleaner. I would recommend to use this as a helper in between a good deep clean when you vacuum weekly. As far as picking up hair - it doesnt do as great of a job as my Dyson Ball Animal Hair Vacuum, but for a robot vacuum it is pretty dang awesome. It does a wonderful job at getting up the hair that my Golden sheds in between my deeper vauuming sessions. I do have to clean out the dust pan and bristles every now and then to help prevent the hair from getting stuck. However, you have to do this with regular vacuums anyway. Suction Power - i wouldnt say it is as great as a regular vacuum cleaner, but it does a great job for it being the size that it is. It picks up pretty great. overall im very happy with the current cleanliness. Other good points - easy to set up - easy to use app - makes map of the house it cleans so you can ask it to clean specific parts of the house - has a self empty feature. I can just pick up the canister and go empty it directly into the trash can. Cons - can be a bit annoying to let it run if youre home, it could get under your feet - loud when emptying the contents / running. BUT quieter than a normal vacuum - Not super suitable for smaller homes. our townhouse is a bit small but it works pretty decent.

Vacuum cleans great. I love that it empties itself when full.

It can memorize its own routes and you can micromanage which rooms you want it to do. I see mine make it’s way through a door instead of bumping around everywhere, trying to find the way inside.

All I have to say is it’s worth every single penny! I would absolutely buy again!

First experience with a robot vacuum and not overly impressed. First unit lasted around 6 months before a component failed. Shark did replace it under warranty after I paid a nice shipping and handling cost of the replacement. Cleaning: It does well maintaining but does not deep clean. I purchased this unit due to the multi-floor and because we have a semi-indoor blue healer. The unit definitely keeps the hair from building up but we still need to do an actual deep clean from time to time to get everything. Mapping: I had to delete the first few maps on both the original and the replacement until they looked correct. I was hoping to be able to schedule the kitchen and living room nightly with the bedrooms weekly (dog doesnt get to come into the bedrooms). But when I would use the app to just clean one room_ it would go through the entire house anyway. I gave up on the map/room aspect and just hit the clean button on the unit when I wanted it to run. The barrier function is useless. Unless it already maps the space, you cant set it up. It it also very course in its mapping, there is no fine tuning. I wanted to set up a barrier on out laundry room so that it never attempted to go in that space but would have to let it map the area a few times before I could block it - I ended up just shutting the door. I tried to block the area of the Christmas tree the first year but it ignored it and plowed through the presents and the tree skirt anyway. AI: The programming lacks finesse and the ability to learn. Both units likes to bump into things and turn to discover its boundaries (and never stops). I put weights in front of the doors so that it doesnt shut the door on itself, pick up chairs so that it doesnt wedge between the legs, put a trashcan next to the toilet so that it doesnt hop up on the bottom of the toilet and get stuck, and move the entrance mat so that it doesnt get stuck between it and the wall. It doesnt learn where obstructions are to avoid them. I made tubes to act as barriers around the Christmas tree this year, Ill need to add some weights on them as it keeps trying to push through them. It works ok as long as you are there to fix it when it gets stuck. I do not schedule as I dont let the unit run when Im not home to monitor. Once the warranty is out and this one dies, I will most likely try a different manufacturer.

It does a excellent job. It learned map of house and I can easily use app to clean specific rooms. Easily climbs over high pile carpet and cleans. Transitions easily between hard surfaces onto carpet. Worth the money.

The pros: it does do a decent job of cleaning and works well on my carpet and much better on my tile. It has only gotten stuck once and sadly was under my desk. The unit has gone throughout my home (areas i want vacuumed). The unit is small enough to get under my couches, bed, and will make its way around my chairs and tables. Overall, there is value in the unit and what it can do. Wearable/Replacement parts seem to be readily available and priced reasonably. The cons: the AI/mapping is rudimentary at best. We have cars that can successfully self-drive but we cant seem to get a vacuum to map a home correctly. Ive now reset my unit 3x and tried to get a good map of my home... and to date without a strong degree of success. I get a map. The map has some areas that look like my home, but.. and esp as you get outside my open floor plan area, it seems to struggle understanding where my bedrooms, baths, office, laundry, etc are in relation to the open area. it seems to use the first 2 runs to do the initial map of your home and doesnt seem to up date the initial map much after that... if at all. After that, it just seems to clean what it mapped on those first 2 runs and doesnt really update the map after that (or so it hasnt seemed to in this case). Help resources stink. Theres not much in the literature and even less online. So, do i wait for some sort of notice that the map is complete or do i accept the initial one and it will update it as it learns more?? The unit runs for 60 minutes then docks. It doesnt matter if the battery is 15% at the end or 80%. it docks after 60 min and there doesnt seem to be any way to change this (ive been completely throughout the settings.. and again.. documentation is terrible esp within the app).Evac and resume will pause for 3 hours regardless if the battery charge is 15% (which it needs some charge) or 80% (it should just resume at this point.. but no, its going to sit for 3 hours). it does this regardless if its cleaning or if its mapping out your house. Firmware updates are pushed and cannot be requested. So, lets assume my firmware is out of date by a release or 2. I cannot download and apply it to my unit. it has to be pushed from some central server somewhere to my unit. Im not sure if my release is current or not (2020 is the date of the last update... which may be WHY the AI/mapping seems quite dated in capability). And, if this is the latest version... that would have me question the commitment by the manufacturer for this product. Overall, the unit is good. It does a fair job at cleaning and does offload the stuff it picks up into the bin which does last a while (have the 45 day bin). The unit does a really good job of avoiding getting stuck and if it vacs up something (like a toddlers sock) it will alert you to the issue. There is so much more potential with this device and it seems much of this is software/firmware related (hardware is pretty solid). Im hoping the company makes some changes to allow some more self-service, improves the mapping and AI capabilities, and releases regular updates. If not, then open this thing up to third party tools which will do this for us.

Probably should have bought a brand new one. It was amazing when it worked. But buying refurbished is always a risk.

Started to make a loud noise after using it about 5 times. Looked online and followed possible resolutions to clean out dust bin, check wheels etc., but, did not correct problem. I was satisfied with performance until this occurred.

UPDATED 7.13.2022: About 4 months ago, my Shark deleted the map it made of my house. Thats what it uses to efficiently clean the house and it lets you design No Vaccuum Zones such as under your table where it gets lost for hours trying to navigate chair legs, or where that rug is that is really plush and prevents the robot from getting up onto it. Anyway, Ive remapped and re-set up my rooms and no-go zones multiple times only for the app to delete them again. Ive read online that its a very common problem, but good luck getting anyone in Support to look at it. Without this functionality, its just another dumb robot. Dont waste your time buying it for the Mapping functionality. _________________________________________________________________________ Ive been rocking at Roombak 699 for many years. Three batteries, countless brushes, and a new dustbin lever later, and I knew it was time for an upgrade. I purchased this Shark unit, not really knowing what to expect. I should have done this a long time ago. Lets start with the obvious: - The Shark unit has a predictable cleaning pattern. Once it has run several times, itll create a decent map of your house. Youll want to go in and create rooms or zones so you can tell it where you want it to clean (or dont). You can also create no go zones without having to stick those infrared, battery powered units all over the place. Once this is all set up, this unit will clean your house--taking as long as it takes. For my house, that usually means going back to the home unit to dump its collector a couple of times. Every now and then, it needs to recharge. Roomba didnt do that. It would zig and zag back and forth until it ultimately just lost charge and maybe it cleaned everything, but probably not. - My Roomba was really loud. So loud, you couldnt work or watch TV or carry on a conversation with it running. My kids even asked me not to run it at night because it woke them up (and it was downstairs and they were upstairs). The Shark unit is at least half as quiet so we dont mind running it when were all here working or just putzing around. - How well does it clean? Maybe not as well, but that is made up for by the fact that it can climb over rugs and clean the entire house in one day versus maybe it takes 2-3 days with the Roomba and it gets stuck on half a dozen things, including cliffs that arent cliffs. We have a mix of hard floors and fairly thick-pile carpet. If youre wondering if its worth saving a few hundred dollars on a Shark and trying it out, you should go for it. Im glad I did.
