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

Noisy like an airplane. Fluid consumption is not large. Copes even with windows that have not been washed for 4 years. But not from the first pass. Pros: Washes. Not the first time, you have to do homework somewhere, but it still saves time and effort. Its cons: Doesn't clean corners due to construction. Does not cope with the old plaque from the water on the tiles in the bathroom.
