The Portable Automatic Window Cleaning Robot uses a stable suction motor that keeps the robot attached to the glass surface during operation. Even on large windows, it maintains steady movement while cleaning.

The cleaning pads rotate continuously to simulate manual wiping. This structure helps remove dust, fingerprints, and light oil stains from glass surfaces.
