A rotary body for dust collection (b), which has a pile group tilted inwardly installed on the arc-shaped inner wall of the attachment body (6).
is rotatably supported, and a pile group Z1G inclined in the same direction as the pile groups (c) and (g) of the rotating body is provided on the arcuate inner wall. As the suction tool for the vacuum cleaner moves forward and backward on the surface to be cleaned, the dust collection rotating body rotates, causing dust such as cotton lint and hair to adhere to the pile group, and to remove dust from both piles. It is pushed up between groups w3 and -1 and enters the suction tool. However, in the prior art, the dust accumulates inside the dust collection rotary body (b), and since air does not flow through this part, there is a drawback that the dust cannot be removed sufficiently.
In addition, there is a risk that the rotating body (b) may not rotate reliably as the cleaning tool moves forward and backward, and in this case, dust cannot be reliably attached to the pile groups (c) and (g). However, it has the disadvantage of leaving dust on the surface to be cleaned.
