  • Patent number: 6141814
    Abstract: The squeegee has a washing element which is attached to a support member and covered by a mesh protector. Replacement apparatus provides for rapid replacement of the mesh. The replacement apparatus includes a length of mesh wrapped around a reel. The wrapped end of the mesh is secured by locking the reel against rotation relative to the support member. The free end of the mesh is secured by mesh receiving projections positioned a top the support member which engage the free end of the mesh. To replace mesh which extends over the washer, the free and wrapped ends of the mesh are released and a length of mesh is pulled from the reel and stretched over the washer. Both ends of the mesh are then resecured to provide for a taut mesh deployment over the washer. The reel is removable to permit replacement with a new mesh supply. A cleaning disk for cleaning insects and similar difficult spots can be removably attached at one end of the squeegee.
