Review on HOBOT-298: Smart Window Cleaning Robot with Ultrasonic Water Spray, Smartphone Control, and Remote Operation by Eunu Cha ᠌

The overall impression is 3+. Be sure to buy 10 more napkins. Includes 3 pcs. It’s not even enough for one window. You have to wash it and wait until it dries. Spraying is not necessary. You can dampen the cloth more. You don't have to pay for spraying. It does not return to the launch site. It is necessary to return the remote control in manual mode. All in all, a good cleaner. The window cleans. But for a long time and with a frequent change of napkins. The strip for attaching the napkin (Velcro) immediately peeled off. If possible, ask your friends to try. Ambiguous purchase) in the photo is glass after three rags.
