The window cleaning robot arrived quickly. After use, I can say that here and there it leaves streaks; the spray from the six nozzles is sometimes too large, spraying where the robot has already passed and not returning there. Translation that it works on glass without frames might be a bit confusing, it only cleans the flat surface of windows or mirrors, not the window frames themselves, so you need a sponge and cloth for that ;) It's a pity that the sink doesn't have Polish language support, but overall it's a nice helper. While the little worker is cleaning the windows, you can do something else or indulge in a blissful relaxation. I RECOMMEND, a useful purchase.
