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

Washes with your own money. Washed 4 balconies, 4 balcony blocks. They also washed everything in the house, there are about 15 windows. It leaves a little streaks, but we didn’t take blue rags, I don’t know how it is. A huge plus is that there is a built-in atomizer. Quality is certainly not like hands, but labor costs are never like hands. If you throw it at the sink a couple of times a year, then the windows will be clean and it will be great to wash. If you have extra money, then I can definitely recommend buying.
