Abstract
Abstract A professional squeegee comprising a handle, wiping blade holder and a resilient wiping blade of rectangular cross section. The blade is retained by the blade holder in a floating restraint by means of a longitudinal groove in the blade or the upper leg of the holder and a corresponding longitudinal bead or other protrusion in the other element for mating engagement with the groove. Removable pins engage the holder and detents at the end of the wiping blade to support the wiping edge at the extremities. Holding the blade in this manner allows it to float and assume its true wiping edge without distortion or influence from external clamping.
