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).

Abstract: An applicator for applying paint to a painting pad with no need to pour any paint from the original paint can. The applicator comprises a conventional standard paint can with a lid and a sleeve with upper and lower surfaces to effect a seal between the paint can and the paint can lid. The sleeve rotatively supports a roller which carries a free hanging, flexible, endless paint transfer belt and weight. The belt encircles the roller and the weight. The weight pulls the belt tight and near to the bottom of the paint can. The paint is applied to a painting pad by moving the painting pad across the paint transfer belt and support roller causing the roller to rotate and move the transfer belt down through the paint to the bottom of the can and back up, thereby picking up paint and transferring it to the painting pad. With the paint can lid in place, the applicator and unused paint may be conveniently stored.
