US Patent 7594294 Cleaning implement

A cleaning implement is disclosed which is of the all-in-one type. It has a substrate structure that delivers impregnated cleaning liquid to the window being cleaned, a squeegee to drive used cleaning liquid off the window, and an absorbent to collect the used liquid. A single block of substrate structure can provide the applicator, scrubbing, and collecting functions, as well as filter and reprocess used cleaning liquid for further use. The substrate may be replaced separately from the squeegee, or may be replaced as a unit with the squeegee.
