2. Description of the Related Art Conventionally, a rotary brush incorporated in a floor suction tool has a blade made of rubber or the like arranged in a corrugated shape as disclosed in JP-A-61-33634 (A47L 11/22). It is known that this rotating brush cannot scrape up fine dust when cleaning the plate surface such as the flooring and tatami mats, and the seams of the plate and tatami mats. There is a problem in that the dust that has entered the eyes cannot be scraped out, and there is no effect of wiping the plate surface.

In order to solve this problem, a brush having a pile-shaped member adhered to the entire surface is provided behind the opening in which a rotary brush having helical bristles planted in a spiral shape is provided, and the plate surface is wiped. However, according to this configuration, since the brush to which the pile-shaped member is attached is not arranged in the air flow path, it is not possible to remove dust adhering to the brush,
The brush must be frequently cleaned and replaced, and if cleaning is continued with hard dust attached to the pile member, the plate surface may be damaged.

In order to solve this problem, Japanese Patent Application No. 4-7969 proposes a brush having a pile-shaped member attached thereto and having an effect of wiping the plate surface. When the members are attached, relatively large dust is difficult to be sucked from between the brush and the opening of the floor suction tool, and when the pile-shaped members are attached with a gap, the plate surface where the gap passes can be wiped off. There were no drawbacks.
