Abstract
The present invention provides a glass-wiping device comprising a glass-wiping device body (1) and a signal-receiving device (30) arranged thereon. The signal-receiving device (30) receives a control signal transmitted by a remote control and the control signal controls the glass-wiping device body (1) into action. The control signal received by the signal-receiving device (30) comes from either the obverse side or reverse side of the glass-wiping device body (1), where the side of the glass-wiping device body (1) that is away from the surface of a glass (100) is the obverse side, and where the side in proximity to the surface of the glass (100) is the reverse side. Because of simplified structure, reduced costs and great controllability, the problem of the machine itself acting as an obstacle that blocks the signal is solved.
