Winbot is like a Roomba for your windows.
It’s amazing to watch the little device appear to defy gravity as it wipes your windows clean. It uses vacuum suction to grip the window and a soft pad impregnated with glass cleaner to do the cleaning.
Our tests show the robot will stick to the window incredibly well, and it carefully covers the entire surface until the window sparkles.
An included safety line means you could use robot to clean the outside of a second story window.
