I bought this a month ago, washed all the windows in the house and on the balcony + tiles in the bathroom. Excellent thing. Yes, it doesn’t wash perfectly, but it’s clean, if you don’t dig it for 4+. But it saves time. I tied it, sprinkled it, turned it on, hooked it and started it - that's all, then I went to drink tea. One minus, the spray does not work on the street, sprays air, but blows it up with the wind and does not hit the window, you have to turn off the spray supply every time before starting, so as not to waste it just like that. if it remembered the setting, it would be cool. If the window is at the bottom and the robot always stops at the bottom, then you just press up on the remote control, it rises and you can easily take it off. My wife and I are happy, we learned about such a robot with the children from fixies, immediately bought it and did not regret it. Fire! I recommend.
