ABSTRACT:
An improved flexible wiping blade for the vacuum pickup squeegee of a floor scrubbing machine. A series of small protuberances with spaces between them are provided at the lower edge of the blade on its surface that leads when the machine moves backward. At that time the reverse flexing of the blade moves the protuberances under the blade and they hold it off the floor, thus allowing any standing water on the floor to move under the squeegee. They do not interfere with normal flexing of the blade under normal down pressure, and they permit its wiping action to be free of streaks when the scrubbing machine moves forward.
