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

Electric vacuum cleaner

A floor suction tool for electric vacuum cleaners includes a suction opening formed on a bottom face of a main body casing, a cover defining a front wall of the main body casing, and an abutting member projecting from a front face of the cover and functioning as a bumper between a front face of the main body casing and a wall. The cover is rotatably supported on a rotation axis formed horizontally in a direction of width of the front wall of the main body casing, the cover rotates upward to open the front face of the main body casing when a front-to-back force acts on the abutting member, and the cover rotates downward to close the front face of the main body casing when the front-to-back force ceases.
