We had bought a very expensive back to him about five years ago, which was still working fabulous! However, we are seniors, and it was hard for me to push with the intense suction it had.Our daughter and son-in-law got one at Christmas and loved it for their all wood floor house! So we decided to order one also and this was the best price of anywhere we found! It is super easy to use, and really pulls that dirt out of the carpets and off the wood floors! It’s truly amazing to watch them work, but then again, I am a senior!

Can't believe how much cat hair this vacuum cleaned up!

I'm really impressed with this little sucker (literally)! This is my first robot vacuum so I have nothing to compare it to. For me the pros were: good battery life, plans a route so no waisted time going over the same spot, cleans both rugs and bare floors well, and easy to empty / clean. Cons: really only one - we have a tri-level home and move it from floor to floor. The issue is this unit will only map one floor at a time. So we are constantly relearning new maps. I think Shark could fix this with a program update, so hopefully that will happen in the future. Otherwise I'm extremely happy with it. Oh and got a surprise the one I ordered had two side brushes but they sent me the upgraded version with one brush and a air jet which cleans much better along a wall. BONUS!

I love this! I have four birds and this works so well keeping up with the mess! I highly recommend

OK, I felt like I was taking a chance on buying this vacuum. It has some great reviews as well as poor ones. After letting it "map" my house and using it to vacuum twice, I'm sold. It picks up dog hair really well. It is quiet, which concerned me, as I was afraid it wouldn't have much suction. It did, however, appear to vacuum the same volume of dirt as the vacuum that it replaced. A "Neato", if you're interested. I was hoping that this was the latest model with edge clean. It was not. Although the add had pictures of that model, in their defence, nowhere in the written description did it say that it was the edge clean model. Having said that, I have to say that it worked so well that I decided to keep it. The only thing that still concerns me is it's longevity. I hope it lasts a good long while. If it doesn't, I will edit this review. At this point though, I have no complaints. It has met and exceeded my expectations. I give it my recommendations.

I bought this unit after over analyzing and research due to mixed reviews. Have owned Roomba for years. I am elated with this unit. I had zero problems with set up which was a concern with the wi-fi in a condo. I ran it first without mapping. The mapping honestly was amazing. The condo has bedrooms on opposite ends plus a sitting area plus half bath at entry. It got it right the first time. The floor is all marble with lots of rugs. The first time it ran was mostly on the rug, then went and dumped itself, and proceeded to run again. I have a dog that sheds a lot.Pros:Not noisy compared to Roomba except to dump which takes seconds.Great suction and manages several rug heights.Technology for mapping, covering the floor in total even with restarts, and emptying itself is fabulous.No bags required.See below on the cons - was able to set that area as a no-go zone and still do the master.For mapping, was able to easily merge areas that were not square or rectangle, or odd shapes to label as the family room.Cons:I have a high shag rug in the master that the twirly thing got hung around. It maybe just because it was first run and kept turning but I don’t plan to use it on that rug.Cannot schedule by room at this time. For now, I just start the family room when I go to bed. It takes a recharge to finish it but that is ok since it is at night.Battery will only go to 40% and it takes it back to recharge. I have not found where you can reduce.

Why didn’t I buy this sooner?! I have three dogs and vacuum every weekend but wanted something for during the week to help with dust bunnies and dog hair on the hardwood. I bought this with no expectations but it is amazing! I can schedule it to run on specific days and times and it works great on my hardwood, area rugs and even the carpet in the bedrooms. Really good suction power and now I only use my upright vacuum every other week and it picks up a 1/4 of what it used to weekly! I also like that Shark doesn’t have bags to buy and you just empty the chamber directly into the trash. Highly recommend to anyone on the fence!

Easy to program and does a good job . Sure beats having to vacuum!

This is a fantastic vacuum cleaner that gains knowledge and improves its performance with each run. Love it.

I purchased this as gift for my mother who absolutely Loves her Shark AI Ultra Robot Vacuum it performs exactly as advertised !She was taken back after I installed the Shark Clean app on her phone and showed her that she can create a scheduled time and day to clean a room, all rooms, spot clean an area within a room or Ultra Clean a room along with alerts, notifications and a clean report all through the phone app while she's doing other things.IMHO I think the smile on her face says it all! Well worth the money spent!
