  • Patent number: 8782850
    Abstract: A vacuum cleaner includes a dust collector which includes a first dust separator and a dust container in which a first dust storage unit is formed. A cover is coupled to the dust separating unit and is used to selectively open or close the dust storage unit. The cover is detached from the dust container together with the dust separating unit when the dust container is emptied. The vacuum cleaner may further include a second dust separator on the main body of the vacuum cleaner. In this instance, a second dust storage unit may be formed in the dust collector, and dust separated in the second dust separator may be stored in the second dust storage unit.
