| 1. A cleaning implement for cleaning a window, comprising:
a support head mounting a squeegee blade and a substrate structure;
wherein the substrate structure is impregnated with a window cleaner and suitable to deliver window cleaner to the window
as well as to collect used window cleaner driven by the squeegee blade off the window;
wherein the squeegee blade and a portion of the substrate structure are capable of simultaneously touching the window as it
is cleaned;
wherein the substrate structure has a portion suitable to face the window being cleaned, where that portion has an inset area
sufficiently adjacent to the squeegee blade to facilitate collecting pooled window cleaner in the inset area that has been
driven off the window before it is re-absorbed into the substrate, and an outwardly extending area more remote from the squeegee
blade suitable to contact the window being cleaned, wherein the inset area helps define an open gap that is in part also defined
by the squeegee blade; and
wherein the substrate structure is in the form of a filter is made of a fibrous porous absorbent material that filters at
least a portion of collected used window cleaner when the cleaning implement is used, and then delivers that filtered window
