PROBLEM TO BE SOLVED: To provide a vacuum cleaner which enables a sheet to be automatically attached to/detached from a rotating brush of a suction implement for a floor, which brings about good floor polishing effects by attaching the sheet, and which can be quietly operated. SOLUTION: When a floor polishing mode switch is operated, the sheet is attached to the rotating brush, and a first control means controls a rotation number so that the rotation number can be most suitable for good floor polishing using the attached sheet. A second control means weakens a suction force so that the sheet can be attached without a hindrance. Additionally, a peeling switch is operated so that a third control means reversely rotates the rotating brush at low speed, and the sheet is removed so as to be automatically wound back.
