Abstract
A vacuum cleaner includes a primary dust container that includes a container body, the container body delineating a dust collecting chamber that accumulates dust sucked into the vacuum cleaner and including a waste outlet that discharges the dust accumulated in the dust collecting chamber, the primary dust container also including a waste-outlet lid that opens and closes the waste outlet. A station includes a secondary dust container that accumulates the dust discharged from the primary dust container, and a driving source that generates opening driving force and closing driving force for the waste outlet. The electric vacuum cleaner generates a driving force for opening and closing an air passage connecting a primary dust container and a secondary dust container, without impairing convenience of a vacuum cleaner.
