SharkION Robot Vacuum AV751 Wi-Fi Connected, 120min Runtime, Works with Alexa, Black

My Spouse has wanted a robot vac for a while. Saw a great pre-Prime Day sale for this one, read the reviews and ordered one. We've had it about 2 weeks and have run it all but perhaps 2 days of that. We get a lot of dust in Central Colorado thanks to our near non-existent humidity and we're impressed enough with this that it's now programmed to run daily. It can keep up with that bit of maintenance for us for most of the time and we can do more of the other things we'd rather be doing. Only time will tell how it holds up, but so far we're pretty happy with it.Very good suction on our all-hardwood main level floor (about 1300 ft) that includes many area rugs, many obstacles, a large black dog shedding randomly everywhere he can, and a central raised front entry area that cuts the vac off from much of the direct path between spaces on that level. Takes 90-120 minutes to cover the entire 1st floor spaces using about 80% of its battery capacity. Because of the main floor room layout & path obstructions, it spends a good portion of that time at the end trying to find its dock if it decides it's finished while on the wrong side of our raised entry foyer. I'd expect it would handle a similar sized space that had fewer obstructions a bit faster (Maybe I'll build it a set of removable ramps to get past the entry area). Still considering it's doing the work instead of you, how much should you care if it spends 30 extra minutes doing that job. BTW, this low end model does NOT restart a cleaning cycle if it runs out of battery even though it does "know" enough to sense low battery and then try to find its charging dock. Bottom line - it has enough Battery to get its job done and done well and it recharges quickly enough that you can send it off elsewhere later in the day (or night)This is a random pattern vac-bot - that is, it runs along until it bumps into something and then redirects depending on which sensor gets tapped. It moves rather slowly and while I occasionally cringe as it runs into some of our 3rd & 4th generation family heirloom furniture, it does not appear to hurt anything with it's slow speed and soft rubber bumpers. Others have complained otherwise - we're not seeing that.It has no real trouble with the heavy oriental area rugs we have around the place and even the fringes (about 2" long) along their edges on some don't seem to be an issue. We have found a couple of places where we need to cut back some heavier (1/2" thick) anti-slip rug pads so there is a bit of a ramp at the edge of the rug, but generally this little bot (we named her Rosie) has very little trouble getting up onto some of rather thick rugs. Thin bath mats or the bath towel our dog uses as a food redistribution and sorting location in the dining room are problematic. 90% of the time they'll curl up and Rosie tries to go mountain climbing. She gets around or over those more often than not, but it's easier to just pick them up temporarily. Power cords are also a problem, so we try to keep those up against baseboards or protected where possible. I suspect these are issues with most all of these robot vacs and also with the u-push it yourself types. It's lower profile than some of its competitors, so on occasion it will find a path under something and can't find its way out. This model did not come with any of the magnetic strips you can use to block it from certain areas, but we're going to try some of those to keep it out of those areas. The bot has built in "cliff sensors" so it also won't run off the edge of a stairway. It just senses the edge, stops and turns away. Haven't had it take a tumble yet. The sensors do on occasion get fooled by the wood grain and abrupt grain based color transitions in our floors, but so what. It's a random pattern robot, so it gets to those spots eventually, just from another direction.The dust bin on this one is fairly large compared to others from what I've read. The first couple of times we ran it, the bin was well packed after both runs. By the third run onward, we started to notice a definite decrease and of much lower density. We generally walk around barefoot and my wife could politely be described as a clean freak so we were amazed at how much this little bot was finding compared to us with our larger and higher powered u-push type vacs and how much cleaner the floor felt.After each run, we empty the dust bin, clean any dog (or human) hair out of the rollers and brush out the air filters. Takes maybe five minutes. It's a bit awkward the first few times until you get the knack of opening the bin and how things snap or slide in and out. You do need to replace the brushes and filters at some interval that is going to be dependent on your surfaces and "dirt profile", but it's likely to be measured in months if you just do the basic post cycle routine they recommend in the rather thin guide booklet.Basically, this is a good little lightweight machine for a relatively lightweight price. If you want a robot vac, but the prices of the units with more bells and whistles are scaring you off, this is a good choice to test the waters. If you find you like it but wish it had a few more capabilities for some areas, buy a fancier one for another level or that area in your home. If you find you don't, you're not out a small fortune having paid for features that while nice, are not going to change your life either no matter how cool. I think some of the relatively few bad reviews are from people that expect too much or don't take the time to let their robot "teach" them how to successfully use it. These are not Star Trek level intelligent devices. Bend a little to meet their needs however, and they are really helpful gadgets to have around.Now the bad news and why I took off a star. The APP / Alexa Skill. Clearly the developer thinks they have better things to spend their time on. This is one the poorer set up apps I've seen in a while. Awkward to use, out of date, would not recognize the model number as valid even though it scanned it from the QR label without issue, awkward connection to WiFi network and disconnects / fails to reconnect (worst of my 24 other very reliable devices on my network in that regard). Low functionality, but if you want to integrate with Amazon Echo/Alexa or Google Home for voice control you need it. It's also handy (when it works, which is still most of the time) to let you know if the robot got stuck somewhere or has run into an issue. You can live without it, but it would be soooo much nicer if this app was a bit more user friendly and reliable. It's my only significant complaint and this part needs some work by the company.

This robot vacuum works. Sort of.First, it's loud. Even on the 'Clean' setting it's loud. And it bumps into everything, loudly, multiple times.Second, is dumb. I know this isn't meant to be an intelligent vacuum. But man it's dumb. It will get stuck under something and rather than realize "Oh no, I'm stuck under something. I should go out the way I came." it will bump around and around and around rather than day ok, I got into this thing old just reverse the steps that got me here and get out. Nope, again it'll just bang around and around and around.It's even dumber while docking. Ok, if I point it at the dock it will find it's way home. But I'll hit the 'Dock' button and watch it attempt to dock. Or will go towards the dock and turn left. Nope something is in the way. Ok spin around, move a foot then spin again on the original direction. Oh shoot someone is in the way again.... Could it be the same thing that was just on the way? Yes on fact it is. I watched it do this for 10 minutes. Finally I took pity on this little machine and put it right in front of the dock. Luckily, it found it's way home then.Third, it will not sync with the app. Rebooted the vacuum. No luck. Rebooted vacuum and my phone. No luck. Rebooted the vacuum, my phone and my router. No luck.Fourth, circling back to is lack of intelligence. I will watch it miss something on the floor. And it will go along and odd angles completely missing that spot.Now if I run it for an hour the odds of it going over that spot is good. But listening to this thing suck for an hour and bang into the same object or wall for an hour isn't pleasant."Oh, just turn it on when you leave the house" you say... Yeah, half the time I run it something had become stuck in the brush causing it to turn off. I don't blame the vacuum for this. But if I could run it at home comfortably, then it wouldn't be an issue.Unfortunately, this going back. It's easier to endure vacuuming for fifteen minutes than to listen to this thing suck and bumble it's way around the house.

I have had the robot for a year now and have been very happy with it's performance. Never bothered with WIFI connection or remote start, not my thing. Docking can be a problem as I have it tucked away and a lot of furniture around docking station so it is hard for it to line up with docking station, so I help it. It's best to empty dust out after every use and clean filter. I bought the replacement package and have replaced everything once, filter and 'whiskers' 2 additional times.

I've wanted a little robot vacuum for a long time. One I could control via my Echo and was slightly "smart". My home gets dusty fairly quickly and I have bad dust mite allergies so cleaning can be a literal pain. I mostly wanted the vacuum for one room, my bedroom. I don't know how efficient my little Baby Shark would be in a larger space, but for a smaller space she is perfect. I've run her about every 3-4 days and the dust cup is always fairly full, and I always notice how much easier it is to breathe dust-free after she's done her routine.Set up was a breeze. Snapped the brushes into place, set the dock up, downloaded the app. Easily connected to my wifi and set up the Shark skill in my Echo app too. I had to name the vacuum, and I have a larger non-intelligent shark vacuum, hence "Baby Shark", but now I can inform Alexa to start cleaning. The Shark app is nice. I can also control the robot from there, see how long it has been running, switch modes, see how much charge is left, or dock it, all without being in the room. It is a fairly simple intuitive interface.The battery life is sufficient for a good clean. After about an hour and a half she's down to 50% on the Max mode. She won't pick up large items but I'm always amazed at how much dust she gets. My hair is long and sheds a lot but she's an expert at getting that up from my vinyl floors and my thin rugs too. The dust cup is kind of small but it holds the dust she picks up with a little spare room. As for noise, she's on the quiet side for a vacuum. I've easily concentrated on work at my desk or watched a show while she's running. She does have a few beeping sequences when she's turned on, switching modes, or docking. I find it cute but might annoy others. The indicator lights for wifi and charging are pretty standard as well. I like the option of scheduling her runs, but I generally just set her to go when I have a little time to pick up some potential obstacles in her path.She can get in the awkward corners under my half circle corner shelves that I struggled to clean with the regular vacuum. She goes under my bed with ease. Under my desk and my desk chair as well. I do make sure to lift all the cords and trip hazards from her potential path. She so far hasn't gotten stuck or gotten something tangled in her roller. She doesn't map anything intelligently like some more expensive models, but she does seem to get into all the corners and under all the furniture on a single run. It may take her a few go arounds to get into a specific tight spot, but letting her go for at least an hour generally she goes over everything possible.Overall I'm very happy with Baby Shark. We'll see how long she lasts with casual use.***2021 Update 6ish months in***Well my poor baby shark died today. She was beeping continuously and not connecting to wifi. I tried some troubleshooting steps on the app and then called customer service.It’s not the first time I had a Shark product die on me. But I’m never upset because the customer service for this company is really amazing. I called and connected right away with someone we did a video-call and identified the problem. Long story short, it had an internal error so I’m being sent a replacement for free.The battery life stayed pretty consistent through this time period. A little disappointed the machine died so quickly when I really use it 2x a/4 hours a week at most. But on the other hand the company stands by their product and I’m getting a replacement. Thought I’d update my review about it.

the only problem i have had with this is it sometimes has a hard time "docking" when you are finished and sometimes gets confused when it goes between tables etc and you have to manually pick it up and move when it gets stuck; other than that, good value product
