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 ().

An electric cleaning device circulates exhaust air from an electric blower to a floor intake tool. The exhaust air passes through an exhaust guide, formed as one element, in a main cleaning device unit from the electric blower through a hose to the floor intake tool. The exhaust guide is a resilient unitary resin part with sufficient resilience to permit compression for installation. The springback of the exhaust guide seals the exhaust path against leakage.
