Utilizing the principle of clock gears (low speed, high torque), along with wind energy storage and simple water filtration to reduce moisture and resistance, enables continuous rotation for cleaning, achieving the "rolling stone gathers no moss" effect. This overcomes the problem of insufficient manpower for cleaning. It accomplishes the maintenance of a polished surface and serves as a warning system for traffic conditions.
