Abstract
A windshield scrubbing and wiping blade assembly includes a scrubbing blade having a mesh covered scrubbing portion and at least one wiping blade in parallel, spaced apart relationship with the scrubbing blade. The mesh and the associated scrubbing portion of the scrubbing blade define side channels for receiving and transporting debris removed by the mesh from the windshield. In the two bladed embodiment of the invention, the scrubbing blade is shorter than the wiping blade whereby the scrubbing blade is maintained out of contact with the windshield during the portion of the wiping cycle in which the scrubbing blade trails the wiping blade. The mesh has edge margins which, in accordance with one embodiment, are beaded. The beads thus provided are received by and mechanically locked within longitudinally extending bores formed in the scrubber blade thereby avoiding the use of adhesives for securing the mesh to the scrubbing blade.
