Patent attributes
A brush for a car wash has radial arrays of fingers cut from flat sheets of closed cell foam. The finger arrays are stacked atop each other with interposed spacer discs, bonded together to form sections of the brush. A top brush has a center section core formed by the spacer discs of a larger diameter than two smaller core diameter ends to provide a larger diameter center section core caused to roll when encountering a vehicle surface to pass over the some without damage, and smaller core diameter end sections able to accommodate antennas with less bending. The fingers of the scrubbing section of the brush are short, no longer than and are held sufficiently stiffly to support the brush on the side rails of pickup cargo beds at a high enough height as to avoid finger contact with the cargo bed bottom surfaces.
