Abstract: A motorized wiping device for cleaning rear and side view mirrors of trucks, buses, trailers, and other heavy vehicles, in which the mirror is mounted externally on the vehicle. Such mirrors being normally wide and high, a rain or snow storm or fog can render them unusable, and the invention is intended to wipe them off as needed. A motor in a housing drives a wiper blade movable over the mirror, with a reciprocating coupling linkage from the motor to the wiper blade, and either a separate battery may be in the housing, or direct connection be made to the vehicle battery controlled by the operator.
