Shark Detect Pro Self-Empty Robot Vacuum with NeverStuck Technology, Auto Deep-Clean Carpets & Hardfloors, 30 Day Capacity HEPA Bagless Base, for Pet Hair, WiFi Black (AV2820S)

The biggest downfall of this robot by far is the app. It's simple, does the job, but compared to the competitors, it's just lacking. First, it kept giving me an error when setting up for the first time. It said "Registration Error", over and over again. No explanation for the error. It was only hours later, while on the phone with support, that I noticed it was set up for the UK and not the US. Why? Because the app is so buggy that it does not display large fonts correctly and it cuts things off. So all I could see was "United" and accidentally selected "United Kingdom" rather than "United States". But the app was not versatile enough to deal with this or even explain what was wrong. The auto mapping feature in the app is fine, very good even. Though the room selection is clumsy, and has a minimum room size, so forget closets or hallways or "L" shaped rooms. The *only* options in the app for cleaning are eco/standard/deep cleaning, and matrix cleaning where it will vacuum in both directions. That's it. No "empty dust bin frequency" or "empty dustbin now". No "treat this like a rug" or floor type selection. The robot is not shown on the map - if you want to find it, you can just make it beep. And you can only use this for a single floor, no way to use on multi-floor houses. Users of Roborocks or Ecovacs will be surprised at how simple the app is. The sad thing is that the app is usually the cheapest/easiest thing to develop, since you only need to develop it one time for all the models. But they went with simple, and truly, for most uses, it's fine. The vacuum itself is really great...too great. In fact I ran it in deep cleaning mode, not even matrix mode, and the dustbin was so crammed with dust, it could not empty...error message. The debris came out in an accordion pleated solid 2ft panel of dust! I can guarantee some spots were missed because it was so crammed. This means it *must* run more often so dirt/dust won't build up, otherwise it just won't empty itself often enough while cleaning to deal with it. So I am glad I got this model as it does the job I need it to do and does it well. It doesn't get stuck, it sucks the hell out of the carpet, it is bag-less, and it has the "matrix cleaning" thing which should improve cleaning even further. And, it's priced very well. I just wish such amazing vacuum developers like Shark spent more time developing their app. Though the technology-averse may prefer it this way.

Works as it should. It definitely saves me time to go do something else besides clean the house. Sometimes you have to make it clean an area twice but that’s ok

I’ve waited over 6 months to write my review to make sure I could give an accurate detail of my experience with this item. I use this robot daily in a 1600sf single level home with two large hairy dogs in a dusty Texas city. This vacuum is the bomb!! I love it and reach don’t know how I went this long without it. You can hear it vacuuming but it’s not loud enough to be annoying. I am not however impressed with the app. It logs out a lot on its own, and it has dropped my map a couple of times and overall it’s not real user friendly, but it does keep you informed of its locale and it works. I do have to clear the floor of dog toys, socks and bathroom rugs for it does tend to get snagged on items and then just falls asleep in place. Don’t buy the secondary market parts, buy only Shark parts because the vacuum rejects them. The vacuum to me, was and has been a great purchase. I highly recommend maintaining the filters and just give it a good cleaning it out with your house vacuum monthly to keep up its life. It’s my favorite household item. Charging speed could be a little faster but it’s not affecting my love for the product.

Does a good job and cheaper than the Robo brand. Easy set up. Make vacuuming chore so easy.

After 6 months of watching this robot vac trundle around my house, I have decided my opinion is "meh". It absolutely does map the house out very well. It goes places I didn't expect. I doesn't get trapped in electric cords. However, if you have HVAC registers in your floors it thinks it's driving off a cliff and sometimes get stranded on them. I decided on this unit because it's supposed to pick up pet hair with ease. Not so much When it's freshly emptied it does just OK. Once it runs for a few minutes it starts piling up everything instead of picking it up. It's also supposed to get right up to walls and corners. Again, not so much. I have a 3 legged table that causes it no end of confusion. It just sits and bumps against the leg, till I go rescue it. So overall I gave it 3 stars. For what you pay for this model I expected a whole lot more.
