Abstract (en)
[origin: WO2009069274A1] In a vacuum cleaner main body 1 with electric blowers 5A, 5B housed therein, a common dust collecting chamber 4 is provided which communicates with a suction side of each of the electric blowers 5A, 5B. A controlling means 6 is provided which is capable of controlling the driving of the electric blowers 5A, 5B independently. Check valve units 43A, 43B for preventing air from flowing backward to the dust collecting chamber 4 side are provided in accordance with the electric blowers 5A, 5B. Even if either of the electric blowers 5A, 5B is driven, the check valve unit 43A, 43B prevents air from being sucked into the dust collecting chamber 4 side from the stopping electric blower 5B, 5A, and suction force can be secured.
