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

Different pros: Very soundly washed the glass on the panoramic balcony, where it is difficult to reach out with a telescopic stick and other devices. From the first time, of course, it was not ideal after a dirty winter, but in three passes I washed it for a confident 4+. In the corners and at the joints with the frame, of course, I didn’t wash it, I had to hold it with a rag. I was absolutely satisfied with the result, I would not have laundered so well myself. And much less time spent. Got cons: The cost of the device itself and replaceable cloths, but similar ones can be found on Ali is much cheaper.
