I had thought about buying a robot vacuum but made the mistake of buying a cheaper one and I hated it. Years went by and I decided again. I have a Shark upright vacuum and am sold on Shark. After seeing that they now have a self cleaning attachment, I got excited because I know how little the actual unit will hold. So after days of reading reviews, I decided on one but it was pricey. So I saw that they had a used one for about half the price. I got it and whoever had it before never emptied it and it smelled bad. Sent that back and went review shopping again and found this one. It cost more for a new one but after the last experience I decided I didn't care. A new one it was. I am so pleased about getting this one and it being new. No one else's problems and no smell. I set it up on my phone, which I have little experience doing, by myself. I mapped out my rooms and did a test run that went well. The next day would be the big experiment because I had it scheduled. The first scheduled run started on time and it went through my entire condo going in areas I didn't see it going through during the test run. I followed it around like an idiot just amazed at how it knew where to go. I only have it scheduled for the first level of my condo because it can't go up the stairs. But I only have my loft up there anyway. I'm guessing it cleaned about 600 sq ft, which is my bedroom, bathroom, hallway, kitchen, living/dining area and my entryway. It went from my medium height carpet, down to my kitchen/bathroom linoleum floors with no problem. It also went up on my high shag rug by my bed and the high bath rug in the bathroom! After it was done, it went back to its dock and it only took about 5 seconds to suck all of the dirt/pet hair into the container, I saw that it had used about 50% of its power. So it could have done 1,200 sq ft before a charge if I had needed it to. I had it scheduled to vacuum every day but have changed that to every other day as it did so well. I should say I have two cats and a teenager living with me here. One thing that I make sure of is that everything is off the floor, which makes me keep the house nice. If there are things on the floor, it will go around them and you won't get the full vacuum you desire. Even make sure electrical cords are off the floor too. If you have high enough furniture, it will go under that as well, which is a treat. The instructions it comes with are not detailed instructions, but a look on the internet or YouTube on how to set it up are great. Thank God I gave the robot vacuum another chance. Love it! UPDATE: I have had this Shark for a little over 2 years now and still love it. It has become a member of the family. lol I just wanted to add how it is holding up. I have learned all of its little issues, like sometimes it doesn't go when scheduled only to find it didn't dock correctly and it didn't charge, or something gets stuck in the bar that I have to pull out. I decided to buy replacement filters for it. I have kept it the actual robot clean, but haven't thought much about the filters on the inside of the canister, the suction part of the machine. Let me say, you need to keep those filters clean! I didn't even realize there were filters in there until I bought replacements and saw all the different type of filters it used. I had to pull up a YouTube video to see where they all were. I was amazed how filthy everything was in spots I didn't know existed. Just wanted to give you all a heads up to make sure you realize there are filters on the inside of the canister that should be periodically replaced or cleaned. They sell on Amazon a package of everything you will need to keep all the removable parts replaced and clean.

TL;DR: This robot vacuum is awesome and worth every penny. Highly recommend this vacuum to everyone, my wife agrees! Happy wife, happy life! Might buy another for my upstairs. For a robot vacuum, it does what I expect and makes my life easier. I don't make it pick up large debris, robot vacuums seem to perform best with small debris. Large debris may get stuck or caught. Lidar works phenomenal, but with some hiccups when mapping house (mostly human error). Routing around obstacles works well, slows around objects and if anything is bumped it's so light and cushioned, it's not a problem. 5 stars overall. 4 stars deep cleaning and suction leaving room for improvement, it's a robot vacuum, what do you expect? Probably has Alexa integration, but I use Google assistant and it works great! --- I ordered this back in July 2022 and got it end of the month. I waited some time to let the excitement die a little before posting a review, but it never really did. This is my first robot vacuum and one of the best purchase decisions I have made this year. When researching for the right robot vacuum, I found that most of the highly rated vacuums don't seem to make it past 6 months or a year when reading reviews. Also manufacturers seems to make new models every year, so finding something that is reliable and lasts longer than this timeframe is hard to find. Of course, I am only onto my 5th month of owning this vacuum. When I broke the vacuum out of the box, my first inclination was to take it out and get it started. But thinking about the other reviews I have read on this vacuum and others like it, I wanted to read the instructions first. This is not a regular vacuum that you plug in and push. It has lots of little parts that make it different and potentially not taking care of it properly could damage the device. So anybody reading this, read the instructions first. Understand how to properly take care of it and clean it. Also, comparing to other reviews, clean it regularly. Now for my somewhat long review: Is it quiet? Yes and no. It is a robot vacuum, how loud do you expect it to be? You're not doing the work, but it is. It is quieter than a regular vacuum, but no idea how quiet other robot vacuums are. If a robot vacuum is loud or quiet, who cares? What matters is that it can clean stuff. Can you watch tv while it runs? Yes you can watch tv. Just turn up the volume a little, no need to blast it like when running a normal push vacuum. Can it pick up everything? No, it's a robot vacuum. Don't put too much trust in it. What I typically do is remove all obstacles (cords, bags, blankets) from the ground and any larger debris that might get caught in the motors (cotton balls left from the dog, pieces left behind from chewed up toys, strings from rope toys). Dog hair? My dog constantly sheds, but has short hair. I run it twice per week on thin carpet and once per week on hard floors. I don't notice the dog hair until I see what the vacuum picked up and it does a great job! The majority of stuff this picks up is dog hair and a lot of it. For longer haired dogs or thicker haired dogs, I assume this will get the job done as long human hair doesn't get stuck at all like my regular vacuum does. Small leaves? It picks up small leaves and debris similar size, but may leaf some behind. It also might get caught in spinning brushes and make a slightly louder noise on hard floor. I waited for it to finish and then pulled the leaf out, no harm. Dog kibble? Ok this one was an accident, didn't see it against the brown colored floor before starting vacuum. Sounded like the robot was choking and about to die, literally. I had to stop it right away and retrieve the small rock sized (width of thumbnail) dog food from the vacuum. Can you run it when away from home? I read too many horror stories of vacuums cleaning pet poop, but it is not the reason I don't start it when I'm not home. Like the last two points, if something gets caught, you need to be there to fish it out. I may have spot checked the floor, but even that sometimes isn't good enough. Also, one time a week or two ago, it finally got confused and couldn't move past a futon leg. It kept spinning back and forth (maybe for 5 minutes) until I nudged the futon half an inch, then it broke free of its endless loop. This was the only time this ever happened since I got it. Every other time it does an excellent job of finding its way through, even finding its way through a jungle of table and chair legs. Lidar mapping floorplan? Simply amazing! I had it map 4 different rooms. The first time was great, but missed a few minor areas, of which was my fault. I left things on the floor and in the way of the robot when it mapped the floorplan. The second time, I removed the obstacles, but it didn't map another room properly. The third time, I removed a chair, which the robot vacuum had just enough clearance to fit under (1st time it went under, 2nd time it did not), so that it can map that area of the carpet and not count it as a wall. Lidar in general? It works great to avoid obstacles and get around legs of any sort. Only thing is if the leg is curved, like my kitchen table, it doesn't know when to properly maneuver around it. But no worries! The bumper is amazing! It lightly bumps in to obstacles and the vacuum does a minor adjustment to figure out how to go around it. Damaging furniture? Nope! Doesn't happen. The robot is so careful around obstacles and even when it does bump things, its lightly bumps it and doesn't scratch or anything. When it approaches obstacles (walls or furniture) it moves at a slower pace. This thing is intelligent. Suction? For a robot vacuum, it does everything it needs to and does it very well. There are different levels for suction in the app, I have only needed to use the normal section. The max suction I have never needed to use, but it is an option if things get too out of hand. There is also an ultra clean option, not tried it, but think it just spends more time going over stuff. If I ever try ultra clean option, maybe need to change deep clean star to a 5, but I'm making the assumption that it will never perform as well as a normal vacuum. Battery? I run two rooms per day I run it, but sometimes do all 4 rooms when I forget to run it. It lasts easily to finish all 4 rooms with charge left over. I'm guessing lowest percentage of battery life was 35% or 40% after doing all 4, this is a wild guess though, could've been higher. For 2 rooms it's usually at 60% after it's done, that I know for sure. Emptying? It has a bin that it empties to. If the robot either runs for too long (or not sure if it senses if it is full of junk) it may return to the docking station to empty itself. This system works great, but the bin needs to be cleaned out occasionally. There is also a filter in the bin system that needs to be cleaned, just like regular vacuums may have. App? No issues running it on my Android. Can select rooms and see the layout easily. Drawing rooms works great as well! Robotiness? It makes all the noises a robot vacuum should and it's awesome! Just thought you should know! Beep boop boop! Ratings: I give it 5 stars because as it is a robot vacuum, it meets all of my expectations. 4 stars on deep cleaning and suction because it isn't perfect, but is excellent as a robot vacuum. I haven't used my regular vacuum in the areas that this one runs because it seems to do such a great job. Integration with Google works great! I don't use Alexa with this one. Again, this is one of the best purchases I made this year. Definitely recommend this vacuum to everyone. Don't spend $1k on something else.

UPDATE: I've had this Shark vacuum for a little over a year now, which means I am no longer covered under the warranty. Figures, since it doesn't work anymore. It started throwing out codes because of the cliff sensors. A bit frustrating as it's only used on the main floor and there is no place, at all, where it could possibly fall. For some reason though, while sitting in the middle of a completely flat floor, it thinks there's a ledge it's going to tip off of. I googled and googled. I tried the tape trick, the paper trick, anything where you could try and fool the sensors. None of that worked. I reset it multiple times. Unplugged it for weeks. Deleted the robot and rebooted. Everything. It starts, gets a few feet into cleaning and then no matter what I do or where I set it, keeps telling me it's detected a cliff. There. Is. No. Cliff!! I have no idea why they don't include a feature where you can turn off those stupid sensors, but they really need to consider this as during my googling, I discovered I am far from the only one with this problem. I now have a robot vacuum that just sits there, unplugged, until we do our next dump run. Original review: We have an Anatolian Shepherd/Hound mix. Never in my life have I had a dog that sheds like he does. There is hair everywhere. I could sweep to my hearts content and all he has to do is walk by and it's like a hair storm. We already had a robot vacuum but it was an older one. There was no wifi or mapping capabilities and it definitely didn't have any way to self empty. Unless by self empty, you mean I did it. I mean, it worked well enough.....when it didn't get stuck in a corner, under the couch, in the bathroom, by the bed....I could go on. It also had preferences when it cleaned. By preferences I mean it would clean one area over and over while completely missing others. I needed something better. I decided to splurge and purchase this one after researching for weeks and reading all the reviews I could find. Now, before I go on I should note that we have no carpet anywhere in our house. Even our kitchen floor mats are made of PVC material so I can't say how well this would work if you have carpet. When it came to set up, it was a breeze. I downloaded the Shark app as instructed, set up an account and it connected to my wifi and Alexa with no issues. I didn't even think of coming up with a name so I just picked one that Shark suggested. The good thing is that you can change it later if you want. I let it charge and then started the mapping of our main floor. Our house isn't huge so it only took a little over an hour to complete. Once it mapped, I was able to add names to rooms via the Shark app. This comes in handy if you need a deep clean of one particular room or don't need the whole house done. I then let it loose to vacuum. It did a couple rooms before going back to the base and emptying and then went and finished the rest. It didn't get stuck anywhere and there was no going over the same spots while completely missing others. The whole process took about an hour and I was able to get other things done while that was going on. The best part is that it did a fantastic job of getting up the dog hair. We decided to set up a schedule for it to vacuum every morning. We are both at work so Mr. Steve McClean is on his own. I went into the app and just picked the days and times in which I wanted it to run. With this daily schedule, we have noticed less and less hair accumulation on the bottom of our socks. If that doesn't scream success, I don't know what does! If I have to give a negative, it would only be that I don't like how loud it is. If you are trying to watch TV or listen to music (without earbuds), you won't be able to hear well when it's in the room. Since we aren't home when it vacuums, it's not really an issue but still something to mention. It isn't quiet. Aside from that, I absolutely love this thing and couldn't be happier with its performance.

First time with a robot vac. Did research and read all reviews, pros and cons and decided this was best for price. Ran for first time today and here are initial observations. Will update as I use it more. 1) this is not a plug and play item. I did have to spend time going around the house taping down extension cords, moving small items that can get knocked over, and marking where certain items of furniture are because apparently if an item moves from location it was at when robot mapped area it will get confused ( there were several reviews that mentioned that as an issue so I just went ahead and marked items that tend to be moved like a coffee table, and chairs (I used little pieces of a tape called “ gaffer tape” which is excellent because it holds well but doesn’t leave ANY residue when removed. Available on Amazon. 2) the model number used on amazon for this item is NOT the same as the model number on the robot, important because when calling tech support if you give this model # they don’t know what you’re talking about. 3) Had no problems setting up and connecting to wifi. 4) ran it on ECO mode because some of the reviews said it was better while it’s still mapping the house -will map it faster because battery lasts longer. I HAVE PETS therefore endless hair and debris and was impressed with suction at the ECO level which is the least strong suction setting. I Won’t try the other two modes until robot finished mapping. 5) there were a couple of areas where it got stuck but after a min or two it found its way out on its own, probably best not to help it unless it’s stuck for more time 6) it lasted 2 hrs and had to return to dock to empty itself twice (2nd time there was an issue described below. at times it seemed it wasn’t going to find its way back to dock but it did. 7) when it went through living room it missed area between sofa and coffee table, however, after doing the kitchen it went back to living room and found the missed area. 8) TWO BIG CONS: the previous model RV1000AE (apparently the one I bought is pretty new as of DEC 2020) has a SELF CLEANING BRUSH which is supposed to prevent long human hair wrap around the brush as was a feature I really wanted because this household has long haired humans , this model DOES NOT come with that. It has what they call a multi surface brush which is basically a regular bristle brush where my long hair got tangled and i had to tear, cut it off brush. Big bummer. ACCORDING to tech support one cannot buy the self cleaning brush to attach to this model. You would think Shark would make the bots so you could switch brushes if you wanted. Also, in the first 2 hr run an error message to empty the dust bin in the robot ( not the base) came up. While the bot and bristle brush did a great job of scraping the pet hair off the carpet, it bunched up in the dust bin and the base was not able to suck it up the 2nd time, I had to manually empty robot dust bin. Big bummer. 9) You need BOUNDARY STRIPS to keep bot out of areas you don’t want it. This model DOES NOT COME WITH THEM, whereas the previous model does. Chintzy move by Shark. OVERALL I am happy with it. I hope the problem with the dust bin clogging to the point of not self emptying will resolve itself after continuous use. I have both carpet and hardwood floors ( on which I have area rugs) and it has no problem transitioning from one to the other. Even though it’s not perfect I can now have a daily vacuuming of my house without me having to do it (I have a very bad back and knees and there is no way I could vacuum every day). As the bot is not finished mapping I haven’t tried any of the APP features-scheduling or picking a specific room to clean— I’m hoping the APP will work well because that was one of the major complaints I read in all the reviews.....the reviews I read were for the previous model because at time of purchase there was only one review for this model. As of now worth the money, it was on sale for $499 when I bought it. 12/25 update. On original review I had given it only 3 stars, now I give it 5. One of the CONS mentioned previously seems to have resolved, running it every day means less pet hair and debris so the dust bin on bot has not clogged again. still have to check brush for tangled human hair and rip/cut it off but I have to do that with normal vacs so I can live with it. Bot finished mapping house after 4.6 hrs of running ( a lot faster than what reviews had complained about). IMPORTANT, it is best to have the “CHARGE N RESUME feature on while mapping if big house, mine is 1900 sq ft, so it completes map faster. This feature does not mean the bot will re start vacuuming after it charges, it just means it will resume in area where it stopped. Final floor plan was pretty darn accurate (lot of negative reviews about the mapping being inaccurate), also found it relatively easy to create rooms. Have an iPhone 11, don’t know if type of phone was the issue for those who complained about difficulty with the feature. I do wish there was an option to create CUSTOM room labels. When creating rooms I found it’s best to zoom the floor plan when creating room lines, otherwise the named room may not correspond exactly to the actual room. This feature is a must because bot only completes 80% of house on ONE charge, then have to wait 3 hrs, so if u don’t want to wait that long to get a specific room done ....... The actual run time on ECO mode is approx 1hr40mins not 2 as previously stated, and the charge time is approx 3 hrs. The dust bin gets emptied at least once during that time. Many times bot seems to be lost- it will do 1/2 living room then go to bedroom then go back to missed area in living.. not a big deal as it gets it done. BOUNDARY STRIPS- don’t know yet if the NO GO ZONE feature in APP can replace the use of strips- for big areas maybe, but I have strips around pet water bowl and I don’t think I can make that a no go zone so I don’t have to have the strips. Will experiment with that feature as I’m not thrilled about having boundary strips in certain areas. My silly dog was initially scared of the strips and wouldn’t walk over them to get to her bed. Dog doesn’t love the bot she’s a scaredy-cat so she goes outside when in use... it only took the cat 2 runs of bot before she realized it’s harmless... hope to see her riding it some day :-) .... I am still impressed about the amount of stuff this thing is sucking up on ECO mode, and it is not overly noisy.I can only assume the other 2 modes are suction beasts but probably a lot noisier and drain battery faster. Though not perfect, if one is willing to spend the time for set up and understanding it’s quirks, it is definitely worth the $$$ ...I’m very happy.

I bought is vacuum as an upgrade for our original shark vacuum. It cleans both my rugs and hard wood floors and does great cleaning up any messes! I would say its compatible with wood or low to mid high rugs. It may have some trouble with denser rugs or fluffy ones to get up all the dirt. It performs amazing when it comes to daily cleaning and ensuring there isnt any dirt on my floors. When it comes to coverage, you can customize this in the shark app. There is even an option to spot clean if you just want a mess vacuumed up! It is fairly easy to use as long as you are okay having an app. I enjoy using it and not having to vacuum myself daily! For the money, I feel its best to get this when it goes on sale. I personally would not buy this full price. I will also note the battery life is short and does not last as long as I would like. Its able to do most of my house but sometimes has a room left before it taps out and has to charge again.

So far, so good. Had to upgrade when my Lefant vacuum quit working. Decided to go with a self empty unit. Works good but it is taller than last one so can't get under everything. The schedule can only be done once a day where my last one could have multiple schedules. Setup was easy, mapping was simple. Can initiate a clean for certain areas which has come in handy for around my bird cages. This one is louder than previous vacuums I've had. Time will tell how long this one lasts.

I have had one of my Shark Robots "Jeeves" for just under 2 Years. He vacuums 1,800sqft daily. We have 2 cats, so he vacuum tons of cat hair! Once a week, I blow out the filter he carries and pop the roller out and remove any hair around the bearing & drive. About every 3 weeks, I replace the filter in the home station with a clean one. The one I remove, I clean, wash and re-use. I have had zero issues with my vac. I have had to replace the normal wear and tear items ... filters, roller brush, crevasse brushes etc. I paid $300 for him, so I am at a point, he has vacuumed daily 1,800 sqft for around .50 Cents a vacuum. I have been very pleased. I ended up buying a 2nd identical robot "Reeves" for the basement. He has also worked well and he never complains or talks back! There are things in the "app" that Shark needs to improve on. Map sharing between Robots is one item! While this robot might not be perfect in every sense, I would not Vacuum my house for .50 cents a day! We ended up buying a Shark Matrix Plus 2-in-1 Robot Vacuum & Mop, Black/Mocha Silver, AV2630WA to mop all of the hardwood. I just started using "Neeves" this weekend. I will review him once he has 6 months plus under his belt. I have been a happy customer.

Jeepers... to say I am disappointed is an understatement. Shark service was great... but I know this is ultimately either a design issue, or the min-brushes which are supposed to sweep items into the roller are not to specification. Neither a good way to start. (LOVE their vacuums, however) As you can see from the photos, the cleaning rollers are smaller that the diameter of the unit. However the overlap is generally quite good. Having said that tho... it means it runs a lot longer and the battery does not last for a full house cleaning, or even the 2 hours it says it should. It is supposed to go recharge itself (I didn't pay attention if it did or not) but when I ran it the 1st time today, it did not do the whole house; missing rooms it had mapped out just the night before.. It did find its way back to the charging station. The serious issue is that the mapping feature and/or laser-eye seems to stop the unit from hugging the molding. This, coupled with the brushes not extending to the widest sides of the unit (beyond the wheels) means that the edges of the carper do not get cleaned! Given this is designed/marketing for if you have a pet, we know this is a big deal. My much older, Roomba i-Robot does a great job of edges and corners. (refer photos) It, however, will just die someplace if it runs out of battery as it doesn't know where the station is unless somewhere near it. The brushes on the Roomba are longer, stiffer, and have a support 'tube' keeping them engaged much better. AND there are 3. Shark has only 1, and after the mapping and 1/2 cleaning the one already took a set. The Roomba brushes have a yellow base. You can see they extend well beyond the wheels. The Shark's have a black base. Unless the brushes are beyond the unit's edge, it cannot clean the below the molding. The Shark leaves at least a 1/2 - 3/4 inch gap that is not cleaned. The Roomba is pretty much 'snug'. Both the Roomba and Shark run in a single direction, yet the Roomba brushes still stick out straight have LOTS of cleaning trips. OH WOW. While writing this the Shark was recharged and seems to be completing the rest of the cleaning tho it is more than 2 1/2 hours later and not necessarily a convenient time. Shark is sending me new brushes in case the length of the brushes are shorter than the spec calls for. If not, it will have to go back as it is not at all able to do what it is supposed to. Relative to the Roomba (which is around 4 years old) the Shark IS quieter and it's very nice to have it empty itself, versus every time I ran/run the Roomba. BUT.. the Shark left bits of lint or paper on two different rugs. They were not stuck-in and should have been picked up. (refer the photo of the rust and black geometric rug) Hence it does not clean nearly as well as the Roomba even with a well-used rubber-brush and regular brush. Meaning the Roomba has two; not the single one as in the Shark. The mapping was less than spectacular. The 1st time it got into some sort of a do-loop and kept mapping a corner of the living room behind a chair. It needed to be recharged and I had to delete the map and start over. As this is an hour job (not the 30 - 45 they say unless you live in an 800 sq ft bungalow) So it was an inconvenience tho not a show stopper. I always pick up small stuff (pails under my office desk, foot rests, rugs with long fringe). I don't pick up 4-legged chairs or office chairs. The Roomba seems to just figure its way around them after circling the legs 360 degrees. The Shark seems to bounce off them and not always come back. These chairs were taken off the floor during the 'map'. And in any event, even if they had been left in place, they would not be in the exact same place each time. So the programming should be able to handle it. (Just went to check on the Shark..... it IS in fact noodling thru the rooms it did not do prior.. So its okay. I just wish the battery were lasting longer.) For while today I ran both. brands It was pretty funny when off-video they ran into each other. I feel a bit sorry for the Roomba. Older, a bit dustier, noisier and fighting for its vacuum-cleaning life. (lol). But it does a better job, truth be told. I'll give the Shark a 2nd chance when the brushes arrive. If it solves the 'edge cleaning' and middle-room cleaning, I'll keep it. But speaking of brushes, I hate that it takes a special tool to get them on/off... something I didn't realize when I threw the tool that came with it. I have a bi-zillion Allen Wrenches and Phillips Screwdrivers, even of the same size. But it seems to be a Star-wrench(?). So I can't put the Roomba brushes on (and which look like would fit!). Hopefully the new brushes will come with the tool. Okay. So my thoughts? It needs to work better once the brushes go in, else it will have to go back as is does NOT clean well, and especially not pet hair since, as those of us with pets know, the fur congregates in the corners and up against the walls.
