An automatic window washer

Recently, incidents in which window washers have fallen during jobs have been reported in Taiwan. If a robot could replace manual window washing labor, accidents would be prevented and window washing costs would decrease. After rain, a certain amount of water remains on windows; consequently, if a robot existed that could automatically wash windows directly after rain, window cleanliness would be maintained and unnecessary manual labor costs would be reduced. Our window washing device can detect whether it is raining. When rain starts, the raindrop sensor is triggered, and the system´s screen displays that it is raining. When rain stops, the system begins to automatically wash windows, or users can start the window washing function manually. It also automatically washes windows when window glass becomes foggy and records time.
