Further, the suction aperture 20 is spread wide into a bell-mouthed configuration toward the cleaning element chamber 19, and an opening in the lower face of the second cleaning element chamber 19 is of such a projecting shape that the rear part of its near center is dented on the rear side.  A communication pipe 56 is pivotally supported almost in the center of the rear part of the case body 15 in such a manner that the rear end part freely rotates vertically and the front end part is opposed to the suction aperture 20. The flange of an opening in the front end of the communication pipe 56 is not covered by the flange of the suction aperture 20 but is opened almost flush inside the flange of the suction aperture 20, at the point of time when the rear end part of the communication pipe 56 rotates to a lowest position. Thus it is possible to realize the smooth suction of an air and prevent a noise from being generated without causing a turbulence.
