PURPOSE:To provide Both functions as cleaner and as air cleaner without deteriorating durability and cost by putting a connecting means to a connection state or separation state by a selecting means, and revolving the second fan together with the rotary shaft of a motor in the connection state. CONSTITUTION:A motor 24 is connected to a controller 54 as selecting means, and revolved at different speed in the normal and reverse directions. A fan 32 as the first fan is installed on the dust collecting bag 18 side of the rotary shaft 30 of the motor 24, and revolved at a high speed by the motor 24, and a low pressure (negative pressure) part is generated on a suction port 22 side. On an air cleaner part 16, a plurality of suction ports 36 are formed on the outer periphery of a case 12 in the vicinity of a partitioning wall 28, and a fan 38 as the second fan is arranged coaxially with the rotary shaft 30 of the motor 24, and connected to the rotary shaft 30 of the motor 24 by a one-way clutch 46 as connecting means, and the fan 38 is revolved at a low speed only in the case when the motor 24 revolves in the reverse direction, and air is sucked from the suction port 36. |
