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

If you need to wash relatively clean windows in a room, especially large windows, it will be useful. In the average washing of city windows from the outside - no. Has pros: It really crawls into the edges better than rotatable robots. Different cons: If the windows are really dirty - it is completely useless. A set of rags (3 pcs. ) was barely enough for a window 1.2x1.2m (for an HOUR of washing), stains still remained and still the corners remained unwashed. The sprayed cleaner blows away with the slightest breeze, and it does not cover enough area for effective washing. The robot regularly blunts on the window, unlike the same 188, it can hang in the middle of the process.
