ABSTRACT:
An improved windshield wiper is described having a pair of squeegees and a brush disposed between said squeegees. The single-piece molded frame of the wiper includes openings along the frame back that are adapted to create a vacuum when the vehicle is moving. The brush spine is preferably perforated such that fluid is drawn from the windshield, into the brush bristles and out through the brush spine perforations and openings, when air passing over the wiper causes a vacuum between said squeegees.
