The Winboni is the first place winner in the International Student Design Competition of the American Society of Mechanical Engineers. Winboni is a small robot that cleans windows. That alone doesn’t set the robot apart. The fact that it is held on by suction is what distinguishes it. Running off AA batteries, this robot clings to the window as it cleans it with felt pads. It is hard to believe that this isn’t already a commercial product. Actually, we thought we had even seen it before, but we can’t find it now.
