A rotating brush including a hollow cylindrical rotor having through holes in its peripheral wall and bristles on its peripheral surface is provided in a nozzle of an upright electric vacuum cleaner. A reflux passage connecting a fan chamber in the cleaner body and an end of the rotor is provided so that a slip stream of an electric fan for producing a suction stream jets out into the nozzle from the rotor through the holes. A fan for sucking air outside the nozzle is provided at the other end of the rotor so that the sucked air also jets out into the nozzle through the holes. In another electric vacuum cleaner, the rotor of the rotating brush is not provided with through holes but the slip stream of the electric fan is caused to blow the peripheral surface of the rotating brush from its end.
