ELECTRIC VACUUM CLEANER
First Claim
1. An electric vacuum cleaner, comprising:
- a suction device including a housing having a suction port opposed to a surface to be cleaned, a rotary brush disposed in the housing and having a periphery partially facing into the suction port, a motor incorporated in the housing and driving the rotary brush into rotation, and a cylindrical bend projecting from the housing and guiding air, dirt and dust sucked into the housing via the suction port; and
an electric cleaner body connected to the bend of the suction device and generating suction force by unit of an electric blower fan, and being capable of winding a sheet around the periphery of the rotary brush and performing the wipe-off cleaning of the surface to be cleaned by using the sheet,the electric vacuum cleaner comprising a sheet-removal control unit which operates the motor to drive the rotary brush in repeated positive and reverse rotations in order to remove the sheet wound around the periphery of the rotary brush.

Abstract
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).
