ABSTRACT:
A power driven driveway scrubbing apparatus formed from the following major components: an outer base housing, an inner base housing, and a push handle assembly. A pair of laterally spaced front wheels are mounted on a front axle that passes through said inner base housing. The rear wheels are mounted on separate rear axles that merely extend laterally from the outer base housing. The inner base housing has a top wall, front wall, rear wall, and laterally space side walls. Its side walls have apertures adjacent the front end of the respective side walls through which the front axle passes thereby allowing the inner base housing to be pivoted about the front axle. A cylindrical brush member extends laterally within the inner base housing and it is mounted on a shaft having its opposite ends connected to the respective side walls of the inner base housing. The push handle assembly is pivotally attached to the lateral sides of the outer base housing and it has structure for applying a downward force to the top wall of the inner base housing thereby causing the cylindrical brush member to be forced downwardly against the surface beneath the scrubbing apparatus.
