A wiper device for cleaning a motor vehicle rear view mirror is provided. The wiper device includes a water sprayer unit (40) connected to a motor vehicle's rear view mirror. A wiper (32) fastened between two slides (31,31') is driven by a motor (11) by means of a pull wire extending to an intermediate pair of pulley wheels in a cross-over manner to remove water and dust from the rear view mirror. A control circuit (60) is provided to drive the motor (11), allowing for a voltage polarity reversal to change its rotary direction.
