1. A method of operating a vacuum cleaner having a suction motor that generates a suction power and a dust container with a compression plate that compresses dust in the dust container, the method comprising:

  • moving the compression plate in a first direction with a driving device while the vacuum cleaner operates to compress the dust in the dust container until the compression plate is forced to stop;

    moving the compression plate in a second opposite direction with the driving device, wherein the driving device drives the compression plate, and wherein the moving results in the compression plate being moved in alternating directions and the dust being compressed against two different surfaces as the compression plate moves in both of the alternating directions; and

    holding the compression plate at positions in which it compresses the dust for a predetermined period of time after the compression plate is forced to stop before the compression plate is allowed to move in an alternating direction.
