The present invention relates to a novel and highly effective design for the squeegee blades used to remove and collect used cleaning solution and other liquids from substantially flat surfaces in manual and motorized cleaning tools. In comparison to the prior art, the present invention provides the squeegee blade with controlled flexibility so that the blade contacts the surface to be cleaned with a wiping lip area that does not change with the applied pressure. As a result of the constant wiping area provided by this invention, the new squeegee blades can operate efficiently on uneven surfaces with reduced wear. Further, the constant contact area between squeegee blade and the surface to be cleaned provides an excellent sealing action, which in turn, leads to more effective removal of the used cleaning solution from the surface and minimizes losses in vacuum that removes the liquid.
