More and more glass windows are being used in modern architecture therefore glass cleaning is becoming a real hassle for daily tasks. Ecovacs Winbot 950 is designed to take care of the window cleanings automatically. The design is relatively compact and light-weight. Jury has actually run Winbot 950 on a vertical wall to test out its cleaning and suction capability. It seemed intuitive and smart. It was also fun to watch the robot working. The overall design is simple but logical; the oversize handle is easy for one-hand operation. The only bottom on the handle makes this hi-tech machine feel friendly and less intimidated.
