  • Patent number: 8347443
    Abstract: A window cleaning assembly includes an elongated pole that has a first end and a second end. An axle is rotatably coupled to the pole adjacent to the first end. A brush head is mounted on the axle and is rotated when the axle rotates. The brush head includes a plurality of bristles that are positionable against a windshield of a vehicle. A motor is mounted on the pole and is mechanically coupled to the axle. The motor rotates the axle when the motor is turned on. A reservoir is in fluid communication with the brush head and is mounted on the pole. A pump is in fluid communication with the reservoir. The pump draws fluid from the reservoir and injects the fluid into the brush head so that the brush head can eject the fluid through apertures in the brush head.
