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.
