An electric vacuum cleaner (1) of the invention is adapted for wipe off cleaning using a sheet wound about a rotary brush (25) incorporated in a suction device (10). In order to wind a sheet (50) around a periphery of the rotary brush (25), a brush motor (44) rotates the rotary brush (25) in a predetermined direction at a predetermined rotational speed. At the same time, suction force of an electric blower fan (42) is set to the lowest level. This achieves the following advantage in a case where a wet sheet is used as the sheet (50). During sheet winding, water and alcohol released from the wet sheet (50) can be prevented from being scattered on a surface (100) to be cleaned. Further, the released water and alcohol do not adversely affect the electric blower fan (42).
