Review on HOBOT-388 Smart Robot Cleaner for Automatic Window Glass Cleaning with Ultrasonic Water Spray, Smartphone or Remote Control by Agata Mrozik ᠌

If the windows have not been washed for a long time, I recommend running dry cleaning first. The result is about the same as after washing by hand, only the process itself is much more pleasant. You press the buttons, and the robot washes for you. Your task is only to change the napkins (by the way, there are a lot of them in the kit). In strong winds, the liquid is not always sprayed where it is needed.
