摘要： An electric window cleaning device includes an operating portion and a wiping portion which are attracted to both sides of a glass of a window by magnets, and are free to move along the glass by virtue of balls. The wiping portion includes a power mechanism and a power supply device. The power mechanism includes an output shaft, a rotary disc and a duster removably fixed to the rotary disc. The power device includes a switch and a battery which are electrically connected to the power mechanism. When the power mechanism is turned on, the output shaft rotates the rotary disc and the duster to clean the outer surface of the glass, as an user moves the operating portion which is attracted to the inner surface of the glass, the wiping portion will also move along the outer surface of the glass to perform cleaning operation.
