Abstract
A cleaning implement is disclosed which is of a multifunctional type. In one form it has a squeegee blade sandwiched by absorbents on both sides. The absorbents can absorb cleaning fluid, and do so when the squeegee is moved in multiple directions. In another form the squeegee blade is sandwiched by the substrates, but has through holes such that used cleaning liquid that is driven off the window by the squeegee is collected in a different substrate from a substrate that delivers fresh cleaning liquid to the surface being cleaned.
