ABSTRACT:
A squeegee assembly to be used in a floor surface cleaning machine includes an elongated squeegee body, a pair of flexible front and rear blades forwardly/backwardly spacedly arranged in parallel relation on the squeegee body, and a blower for applying a sucking function to an interval between the pair of flexible blades through a vacuum hose so that a dirty liquid gathered by the pair of flexible blades after cleaning is sucked up from a floor surface for collection. The squeegee assembly further includes a dirty liquid suction guide mounted on a lower part of a suction hole, which is in communication with the vacuum hose, within the cover member and adapted to guide a sucking force of the blower, which sucking force is sent through the vacuum hose, towards an inner wall surface of the rear flexible blade.
