<P>PROBLEM TO BE SOLVED: To solve the problem that a structure of a drive wheel including an elastic body, such as rubber, and a blade causes effects of raking up and wiping at the drive wheel to be deteriorated more than other part of a rotating cleaning body, and thereby, e.g., dust is left. <P>SOLUTION: The rotating cleaning body includes: a plurality of cleaning members arranged on a cylindrical base of the rotating cleaning body from one end to the other end in a crosswise direction; and a holding member arranged on both ends of the rotating cleaning body and for holding the rotating cleaning body on a suction port body. A fixed brush is included at the bottom face of a lower case and in the rear of a rotating cleaning body storage room, and a fixed brush relief part is provided in the rear of the fixed brush at the bottom face of the lower case. When the suction port body is not installed on a cleaned surface, the fixed brush projects from the lowermost surface of the lower case, and a length of a part where the fixed brush projects is shorter than that of the fixed brush relief part in a cross direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
