Review on HOBOT-298: Smart Window Cleaning Robot with Ultrasonic Water Spray, Smartphone Control, and Remote Operation by Arina Foliez ᠌
Not a bad product, quite normal quality.
Different pros: An excellent device cleans windows very well, ran it on very dirty windows in 3-4 passes, the windows shine Different cons: Velcro fixing rags hold very poorly, after several replacements I had to glue everything in general, everything is ok.
