Abstract
A vacuum cleaner includes a dust collector that compresses dust stored inside a dust container to minimize the volume of the dust. The dust collector would include one or more pressing plates that are used to compress the dust stored in dust collector. Various methods are used to control movements of the movable pressing plates to facilitate the compression operations. Also, various methods are used to determine when the dust collector is full and needs to be emptied.

20. A method of determining if a dust container of a vacuum cleaner is full, comprising:
-
moving a dust compression plate within the dust container to compress dust in the dust container until the compression plate is forced to stop;
determining how far the compression plate was able to move before it stopped;
determining that the dust container is full if the amount that the compression plate was able to move before it stopped is less than a predetermined minimum movement amount. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
