PURPOSE: To reduce an operating force and provide a cleaner easy to operate by depressing one of switches provided opposedly to an operative holder part of a tip pipe to reduce a suction force and depressing the other to increase the suction force.
CONSTITUTION: When a floor nozzle 17 is moved forward and a switch 18 on the upper portion of a tip pipe 15 is depressed by the palm of a hand, a voltage controller 20 is operated to reduce a little voltage applied to a motor fan and a suction force so that a suction force for attaching the floor nozzle 17 to a floor surface is weakened to lighten the operation of the floor nozzle. When the floor nozzle is pulled this way, a switch 19 below the tip pipe is turned on to restore the suction force. Then, a friction force between the floor nozzle 17 and floor surface is so small that the operating force is not large. Thus, the operative property of the floor nozzle can be improved by adjusting the suction force in operating the floor nozzle.
