PROBLEM TO BE SOLVED: To improve a squeegee function and its life by bently forming the squeegee whole body into an approximately bow shape, constituting the development state of a flexible blade into such a shape as forming a part of a conical shape, and attaching the blade in an inclined state in relation to the floor surface. SOLUTION: A floor surface cleaner is provided with a squeegee 6 which is coupled with the rear part of a device 1 for absorbing and recovering sewage left on a floor surface into a sewage tank 4 by absorption force of a blower 10T. In this case, the squeegee 6 is provided with two front/rear blades 6b, 6c which are arranged in a case body 6a and a supporter 6x which fixes the blades 6b, 6c between cover pieces 6a1, 6a2 bently formed into approximately bow shapes. The contact angleθwith a floor surface of the rear flexible blade 6c, which is sandwiched between the rear cover piece 6a2 and the rear side face of the supporter 6x, in relation to the floor face is set in a range from 45 deg. to 70 deg. and the development shape of the blade 6c is formed into such a shape as forming a part of an approximately conical shape.
