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 found that the Hobot 2S was very easy to use. It works best on a window that is not filthy. The cleaning cloth only cleans a small amount of dirt before you need a clean one to replace it. I ordered 3 more cleaning pads and may end up ordering more. Once the dirty to clean ratio of the cleaning cloth is to the clean side, it does a great job and doesn't leave streaks on the window. I think it will be my window bot friend for a long time. I am quite happy with the job that it does.

I really like the HOBOT. We have big windows and a toddler at home, so cleaning can be a challenge. It sticks well and is very easy to use. For tougher spots, I usually wipe manually or run it a few times — but overall, it’s a huge help. It keeps my windows clean and saves me so much time. Love it!

The bot cleaned two window panes then developed a problem where it just went to the side of the window and stayed there without reversing direction (basically, stuck). Apparently this isn't uncommon. We're getting a replacement unit via Amazon, but, you ship a dud and you lose at least one star. Then, it's important to realize how limited this product is: 1) it needs to be plugged in while cleaning. I had assumed it could run on battery power. Having to run power to the machine is pretty complicated with outdoor windows 2) some windows require pre-cleaning .. for things like pollen. So, if your windows were fairly dirty and you hoped the Hobot could finally address the problem without a professional cleaning, it doesn't work like that. It's more like: get them professionally cleaned then use the Hobot periodically to keep them clean. 3) it needs a tether or it might just drop and break .. and if it falls and breaks, that's your fault, not a reason for a return. Basically periodic failure of the suction is an expected issue. So that's kind of a pain with high, outdoor windows in particular - you have to figure something out with maybe first installing a metal hook above the window so you can run the tether through that. 4) you have to be able to firmly press it against the window with both hands So for a high window, you'll be getting the ladder out - you can't use, say, a painter's telescoping pole to attach it to the window. --- Hobot doesn't exactly hide this information, but it's not exactly prominent either - looking at their marketing materials, I definitely did not realize the device was so limited.

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 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.

Hobot 2S is a device that is easy to use and delivers excellent performance. I’m very happy with the purchase and highly recommend it.

It’s good but always drop when working.

I live in Canada. I got this washing robot through the Canadian Amazon. Shipping was from the USA. At the first attempt to use this robot, a serious problem with this device appeared. One of the washing liquid tanks turned out to be not hermetic, because of this, the liquid flows out and it is not possible to use this washing robot. Huge disappointment! I tried to return a defective purchase and to my surprise found that I could not return it and get my money back! Amazon informs me that this item is non-refundable because the box with the robot contains a bottle of washing liquid, which is a flammable liquid and for this reason Amazon cannot issue a return. I don't understand why Amazon has no problem selling and delivering cleaning robots with flammable liquids, but when you try to return a broken item, they already refuse to accept the broken item for security reasons. I believe that such a policy is a direct violation of Canadian consumer protection law. I tried to contact Amazon support, again they refused to return the defective item and advised me to contact the manufacturer in the USA. The problem is that the warranty on this robot only covers the US and I'm not sure if I can get my money back since I live in Canada. Why does Amazon sell items that cannot be returned in the event of a defect, and at the same time, at the time of purchase, they do not immediately warn that this item cannot be returned and that it is not covered by the guarantee? Total dismantling! We can say that I threw almost $ 1,000 in the trash!
