HOBOT-2S Window Cleaning Automatic Robot with Ultrasonic Water Spray, Intelligent Cleaning, AI Smart Route Plan, Dual Replaceable Water Tanks, and Control via Smartphone or Remote

I have to admit I was somewhat skeptical, but after getting one I am very impressed. It cleaned my four large windows in about an hour with great results. Instructions are easy to follow and it's simple to use. We also used it to clean the shower cabin. It's expensive but definitely worth the investment.

For the price, it isn't worth it.My expectations were to have a robot that would run by itself where we could start it, and come back after a few minutes to a clean window. We'd move it to the next window and repeat; freeing us to do other activities.Overall, it needs a lot of human help, doesn't always finish, and isn't very thorough.We started it on a best-case scenario: a large bathroom mirror. The mirror was already fairly clean with some water spots at the bottom. The Hobot successfully navigated to the edges and did the horizontal and vertical cleaning pattern, so it essentially went over everything twice. In the end, there were streaks where the sprayers sprayed, but it took care of the sink water spots pretty well. The cords kept getting wrapped around the faucet so we had to babysit it: making a 2 minute human job into a 10 minute babysitting job. I'd give it a 6/10 on the mirror.Next up were some medium sized windows. It did an admirable job of cleaning the outside of the window, which was pretty dirty. It was nice that it could reach the entire window, where we had problems reaching with our arms. It did a decent job and didn't streak noticeably. I'd give it a 7/10 on this window.Finally, we put it on a large slider, probably 3.5ft X 7ft tall for each side. The treads stopped gripping the window, so it slid awkwardly around in not-straight lines and had difficulties reaching the top. The side sensors couldn't figure out the sides, so it would get stopped on the edge of the window and continue to spray in the direction it was [not] moving, which was spraying on the next window or wall. It never completed the up/down pass because of the tread issue.We tried the outside of the window with a new cloth, and it continually yelled at us about loss of suction and never got more than 2 feet until we gave up. I suspect maybe there were some ripples in the glass that affected the vacuum. I'd give it a 2/10 for the sliders.So now we're left with an expensive robot that barely functions for what we intended. There are 10 days left in the return window, and I'm strongly considering returning it. If it could just do the windows by itself, even if they were a little streaky, it would be acceptable.I wouldn't recommend it based on my experience.Update:I gave it another try and it still yielded poor results, so I am returning it. The biggest issue is that it won't clean without constant babysitting. I had to sit there watching youtube videos as the robot cleaned because it would complain about air leaks or would get stuck. At one point I realized that just pressing my finger in the middle of the device would cause it to work properly. Maybe the suction is poor, but I was using brand new cloths on fairly clean windows.In the end I realized that I could clean the window by hand in 5 minutes, rather than babysitting a robot for 30 minutes.

IT STARTS CLEANING BUT NEVER GOES UP. JUST GOES DOWN. THE PREVIOUS VERSION WAS MUCH BETTER. IT WORKED AND CLEANED GLASSES AND WINDOWS. UNFORTUNATELY THIS VERSION SEEMS TO HAVE AN ISSUE WITH THE ROTOR BAND.

I Purchased this because at the age of 70 my glass sliding doors in Florida need cleaning a lot more than I am able to do. A bit skeptical, I opened the product, followed the directions, and put it to work. Took a few minutes to get used to it, but it is user-friendly. I am extremely pleased with the results. Although the cleaning fluid seems a bit pricey, it takes very little to complete a large square footage of windows and doors. Don’t take any shortcuts, and you will be pleased with the results as well.

Likes:Easy to place on window and get it cleaning.Reaches the top of tall windows, so I don't have to pull out a ladder.Lots of extras in the box. Cleaner, extra cleaning pads, and extra replacement nozzlesDislikesDoes not clean 100% on all windows. The outside of my windows have a bezeled edge and it has trouble knowing where the edge of the window is which causes it to miss cleaning about 5% of the window. The inside of my windows are better but it can still miss corners and the very top and bottom.I feel like the cleaning patterns could be a little smarter around edges and corners of windows. Hopefully that improves with software updates.It's a bit pricey for not reliably cleaning 100% of the window.

We have been satisfied customers of Hobot with 298 model for the past four years. Moving into a new house with more windows, we added 2S model and the results are amazing! I don't understand some of the negative reviews here. If you follow instructions properly, the robot cleans our windows really well. We have contacted their support and they have been very helpful answering all our questions. Highly recommend!

It’s good but always drop when working.

Love this robot and my clean windows!I only have been using it for a few days, but I absolutely love it so far! It saves me time to do other things around the house as I have big windows. It covers all of the surface area with outstanding cleaning and polishing.
