AI Ultra Voice Control Robot Vacuum with Matrix Clean Navigation, Home Mapping, 60-Day Capacity, XL Self-Empty Base for Homes with Pets, Carpet & Hard Floors, Cool Grey, AV2511AE

Let me start by saying I HATED robot vacuums before getting this. I had bought an early model from another brand, and it would randomly run until it hit something turn and repeat. This was basically useless. It never really cleaned, and was constantly stuck, or ran out of batteries before finding its way back to the base. This couldn't be more different. Setup: I was tentative from the start. But, I told it to start mapping and forgot about it. 15 minutes later I saw it on the base and assumed I never started it or it failed, so I opened the app and saw a highly detailed map of my house. I was amazed. It had mapped and returned to the base so quick I assume it didn't work. I used my phone and assigned room boundaries to the map, put a DO NOT GO zone over the basement stairs to be safe, and setup the app to auto vacuum at 6am on M/W/F. Running: I have had only one time it needed intervention. It sucked a small cat toy into the roller and detected the strain on the motor and stopped, asked for help. It took about 60 seconds to open the roller, remove it, remove the toy, and put it back together. It resumed the process and finished. I have had it for months and that is the only time I have intervened. Vacuum quality: Each time I empty the bin I am horrified at the amount of dust and cat hair that it is picking up. It is running 3x a week, and in one week it takes a kitten worth of hair off the hard wood, and enough dust to make you queasy looking at it. It is a powerful vacuum, it gets the entire house when it runs, and does a great job, but it is quiet enough to run without waking anyone up. Pros: Setup, simple. Set and forget. Empty once a week or two or three. Almost no human intervention required. I don't prep for vacuuming, don't tidy up, don't do anything. It just works and works well. Lidar constantly updating the map, it rarely touches anything, so it doesn't scratch walls and furniture, it uses sensors and lidar to "see" the obstacles and work around them. Cons: It takes a recharge to fully do the house. We work from home and I can't tell it the order to vacuum. So sometimes our offices are the last rooms, and by the time it runs, recharges and starts the second half I am already working and it wants to come vacuum my office. If I could set the order of room vacuuming it would be literally perfect. That is the ONLY con I can possibly think of. Seriously, it is THAT good. I don't know what the $1000+ models can do that this can't.

I don’t normally write a lot of reviews, but when I take the time to write one, it exceeded my expectations. This is no different. As many have probably done, I picked this up on sale. And with the 10% cash back on the prime card, it was an easy decision. I’ve researched these for years, but the tech never felt “ready” yet. For me, the wait is over. The setup out of the box was simple, and it did’t take long for the unit to map our house. After mapping, you can clean the whole house, or select which rooms. I watched it for its first mission. I was amazed how it reached every crevasse. It really tries hard to reach each corner, and my experience is that it did just that. At times, it looked like it missed some areas, but it reached every section before returning to the base. Others commented on how it’s not as loud as other units. Definitely quieter than a standard vacuum. We have pets, so you can select a setting to return to the base to empty every 30 minutes. It then returns to the exact location to resume. If it’s cleaning, and the battery is running low, it will return to the base to charge up, then it returns to where it left off. When evacuating the robot, that’s the loudest part, but the base has a hepa filter to avoid the dirt causing odor, or re-entering your floors. The receptacle releases from the base with the push of a button, then one little switch to dump in the trash. Take a look at the pic. That was from only 2 rooms. It was able to easily navigate under the bed, which is always hard to clean. If you have pets, this is a must have. Outside of just turning it on to clean your floors, you can schedule your cleanings daily while you’re away. Nothing like coming home to see clean floors, and the robot back on it’s base charging, and see the trash it picked up through the little peephole. I also linked it to Alexa. Another cool feature is naming the robot. We named ours “Karen”. If you’ve ever watched SpongeBob, you’ll know why. 😀. If an area in your house has an immediate cleaning need, you can say, “Alexa, ask Karen to clean the Kitchen”, then off she goes. Easier than getting a broom or vacuum for sure, and don’t have to leave your couch. Probably not good for exercise, but for someone with mobility issues, I see this as mandatory. It even has a “spot-clean” feature. For high traffic areas that need extra attention, you can select spot-clean on the app, zoom into the area on the map your robot outlined, then off she goes to only clean the section you zoomed in on. Pretty cool. I’ve seen older versions operate, and I was never impressed. I’m glad I took the plunge with this Shark Unit. If you’re on the fence like I was for years, this is your unit (Especially if on sale again). My thought was, if it didn’t get the amount of pet hair I would expect, I would return it. Well, that’s not going to happen. Karen is now part of the family, and we’re considering bringing in a brother or sister to mop the floors. I’ll be researching what Shark has in this arena, you can believe that. Well done, Shark. Well done.

Don't waste your money. I've had a robot vacuum for about 12 years at this point. Samsung, Multiple Neato, and now this Shark. This shark has the worst interface of them all. The robot is supposed to have a "charge and resume" feature, but 3 months now of turning features on/off, completely resetting the robot, relearning the house, deleting the app, and setting it up as a new robot. But the robot vacuums for 5-15 min, the goes back to its base and pats itself on the back with a "mission complete" report literally showing is only did 5% of the house. It's just garbage. Just Google Shark Robot not completing runs and see dozens of Reddit posts of everyone having this issue and others. Even if it is actually VACUUMED, which it doesn't when it does it is the worst of all robot vacuums I have owned. Customer Service from Shark 2/10: Update 1: Reached out to Shark to try and fit it and warranty the item if needed. At no point did a ask for a replacement, only did what was instructed to try and get it fixed. After I called, it took 30min walking through the most basic steps possible with a Level 1 rep. Then.... 45 min on hold waiting for a level 2 tech (not something I asked for). This rep made me completely reproduce everything that I had gone through with the level 1 tech. At no point was there any actual diagnostics done by me or by the rep remotely. It felt like they were intentionally making the repair/warranty process painful just so people give up. The level 2 conversation was another 45 min. So nearly 2 hours after first speaking to someone, they agree it is not working correctly. You would think this would trigger the warranty claim, but no. A level 3 rep would need to call me..... later in the week? Really, after 2 hours of video conference of you literally seeing the machine do all the errors, stops, and failures. Sharks need even more people to see it? They already record the calls, why cant someone just review it? Update2: Level 3 called me at 10:30am on a Thursday. Shocker, I was working and could not answer. Update 3: I call back with my ticket number and speak to a level 1 rep again. He wants me to describe the problem, I let him know I already have a ticket. I tell him the ticket number, he pulls it up and then wants to diagnose. I politely refuse and let him know I was calling the Level 3 tech back, and that is who I would like to speak with. The level 1 rep then speaks to someone, and comes back saying they are going to warrant the item and ship a portion of a new robot (yes portion, not a replacement robot). BUT.... I would have to pay a shipping/service fee. Which is a slap in the face. This unit has likely never worked correctly and has cost me multiple hours of my time this week alone, just to get to this point. There was no good reason this process should have taken +2 hours. They could have asked for a 2-minute video proof of it not working and a 2-minute form to accomplish literally everything we went over in multiple hours. I calmly explain why I would much rather have had my original robot work, I literally don't want a new one, I want mine to work, and it is Shark choosing to do a replacement, not me. So No, I would not pay any fee. He went away and came back saying they will "wave" the fee. I'll update once the pieces of the replacement robot come in. Update 4: Warranty finally sent a replacement. But based on what is written above, I wasn’t surprised it was the bare minimum. They sent a replacement core, but you have to move over brush, battery cover, battery, filter hosing, filter, and brush cover. And the replacement pod doesn’t match at all. Looks like absolute crap. And keep in mind. There tech support spent literally hours looking at this thing on video chat. Don’t but cause the warranty is useless.

I did a good bit of research before deciding on the Shark. We have a Shark upright and another dustbuster size Shark so we are very positive about their products. I chose a spot for the dock that doesn't really comply with the instructions but it hasn't affected the operation in the least. It is under a side table in a bedroom. Works very well from there. I used the app to map my apartment, which it did very well. I closed the doors to rooms i didn't want it to go - either because i just want them cleaned more thoroughly by our cleaning service or i thought it might get stuck on the rugs. It handles rugs pretty well, though. Minor complaint that others have mentioned: it doesn't take the same route each time. And it goes over the same areas more than once. The first time it ran, it got itself stuck under a low riser dresser so i now put a stool in front of the dresser to prevent that. I think the app is pretty slick and easy to use. You can set it to vacuum every day or any odd assortment of days. Ours runs twice a week to be sure the cat hair gets cleaned out. First run complaint: since it was vacuuming under beds, it was probably going places that had not been vacuumed in a long time. So that first time, it filled the bin with cat hair and just stopped in mid run. I had to take it back to the dock but even then it couldn't off load the hair. It was too full and compacted so i had to remove the bin from the robot and clean it by hand. That hasn't happened again though. Just be aware if you have any areas like that. The app lets you do the whole house, just one room, or a selected 5 ft square space. In the app, choosing Spot, it puts a square in the middle of the screen with the house map over laid. You choose the spot by moving the map under the square until it is over the area you want cleaned. It's not intuitive, but once you see it, you know how it works. I read many of the older reviews that mentioned a magnetic strip to keep it from going certain places like off a step. I was wondering where those strips were because mine did not come with any. I almost returned it before the first run because i do have a sunken room and was concerned about it going off the step but it ran right up to the edge, stopped, and then ran along the entire width without a problem. Pretty impressive. It will obviously have trouble negotiating table and chair legs so if you want those areas cleaned you will need to move the chairs. It would also be nice to know how to deal with the sunken area of our home. For now, i take it off the dock and carry it to that room before turning it on. It does the room completely and returns to the starting point where i again have to pick it up and return it to the dock. Then, i have to use the app or the button on top to tell it to return to the dock, which works ok. Im just concerned if this confuses the mapping of the rest of the house. I wish the instructions addressed this issue. UPDATE, Nov 13, 2025: I have been using the robovac for two years now and I still love it. I have discovered a few irritating features- 1. Make sure you don't have anything on the floor that could jam the machinery. My cleaning lady left a dryer sheet somewhere and it got sucked into the filter on the Shark. There is no warning and no other notification that the robot is no longer working. 2. The app keeps asking me to re-logon every time I need to start vacuuming. I have it set up to NOT do that but it seems to forget every so often. It's very inconsistent. The app just needs a little tweaking to be perfect, 3. If you have a separate room that isn't on the same level as the majority of your home, it isn't able to "map" the separate area. That would be a very-nice-to-have feature.

I ordered mine used, which the description said the product would arrive just like new in the original packaging from the manufacturer. It did not. It came in a big brown box and the vacuum was just in a plastic bag surrounded by bubble wrap? The brush wheel also had some hair wrapped around it still. I understand it was used, but I was a bit disappointed by that. But the vacuum itself works amazing! It mapped my house fairly quickly and was easy to set up. It left my floors beautifully clean and picked up everything on the floor. It’s relatively quiet except for when it is emptying into the tank, which is expected. It fits under most furniture and does a great job!

[update May 18, 2024] I'm even more pleased after Buddy has been on the job for six months. He's just a joy to have around. Yes, he has a name now. Buddy has gotten stuck no more than four times while cleaning at least part of the house every few days. I'm still amazed at how much stuff (mostly cat fur) is in the base station when I check it every month or two, because to me the house looks like it's mostly clean all the time now so I don't expect that much "invisible" debris to be collected. The self-cleaning brush roller isn't completely maintenance free, but I never expected it would be. The worst culprit isn't the cats, but my wife's hair. Fortunately it's extremely easy to pop the roller out and untangle the stuff, which I do about once per month. You can hear when it needs a cleaning. The only thing I really wish for is a single-room learning update. No way I want to update the whole house again, but there are one or two small pockets where Buddy just doesn't go. I'd like to be able to update just that one room without having to re-learn the whole house. But, I have to say, this is one of the most unexpectedly satisfying purchases I've made ever. [original review] I can't compare this robot vacuum to any others because it's my first. I will say that I didn't expect it to work as well as it does. We have two rag doll cats that put out an amazing amount of fur. It's either vacuum all the time or just put up with it between vacuuming. Not any more! Sure, it can't get everywhere the fur likes to go hide, but surprisingly, it does get most of it. We have wood floors with area rugs. I was afraid it would choke on the thicker area rugs. They're a pain to do even with a regular vacuum, but it handles them like a champ! It's so refreshing to see the floors so tidy. I'm embarrassed at what we put up with before. Another nice thing is if I make a mess, such as in the kitchen, I no longer care. I just whip out the phone and order up a room cleaning. Now for the big advice. Spend as much time as needed getting the initial exploration, map, and room creation process as perfect as possible. Move everything you can out of the way so it doesn't mistake something like a bathroom scale as part of the house geometry. After the first few tries, there were areas it just decided weren't part of the house because it couldn't get there when exploring. It simply wouldn't clean there even if not obstructed! Once I went through the house thoroughly and got everything I could out of the way, it made an excellent map. When you put things back, the map will remain but those things will just be seen as temporary obstacles. Seriously. It's worth the work. My biggest ask for improvement would be single-room learning. After going to all this trouble getting a good map, I really don't want to re-learn the whole house if I, say, rearrange the furniture in one room. But for now that's not an issue. I initially took off a star for these initial shortcomings but have put it back up to five stars. Overall it's fine. I can't say for sure, but I think it's getting smarter. For sure, it hugs the walls really well now, where it wasn't doing that before. The only downside is I can't say this thing is saving me any real time yet because I end up following it around the house just to watch. lol!

Love my shark robot. The best robot vacuum I have owned. It cleans really well and the app is very easy to use. I appreciate how easy it was to build my home in the app. The sound level is reasonable (how clean can something get without the right level of suction which will cause sound? So many people want performance and silence- that’s not an achievable combo). This little warrior does an amazing job of always finding its way home. It does not get stuck or lost. Granted- I have a relatively open floor plan and I keep the floors clear. Highly recommend! Even my family has now gone out and gotten one based on how mine has performed!

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.
