The PowerWiper follows the wiper arc across the windshield exactly as your conventional wiper does. When you turn on the windshield wash cycle, the PowerWiper still moves over the same wiper arc. However, the wiper blade plus the scrubbing element now move in a 1/2 inch back-and-for reciprocation over 42 times per second, scouring insects and foreign matter from your windshield.

In the same year, Mary Anderson devised a swinging arm that swept rain off the windshield when the driver moved a lever located inside the car.
