Abstract: A cleaner is disclosed. The cleaner may include a housing having an opening through which air is introduced into the housing. The cleaner may also include a filtering unit mounted in the inner space of the housing. The filtering unit may define a dust collection space between the filtering unit and the inner surface of the housing. In addition, the cleaning unit may be mounted to surround the filtering unit. A manipulation unit may raise or lower the cleaning unit within the dust collection space. Furthermore, brush protrusions may protrude from the cleaning unit toward the surface of the filtering unit.

Abstract: A cleaner is disclosed. The cleaner includes: a housing having an introduction opening through which air is introduced; a filtering unit configured to be mounted in an inner space of the housing, and defining a dust collection space between the filtering unit and an inner surface of the housing; and a cleaning unit surrounding the filtering unit and configured to be raised and lowered. When the cleaning unit is in an initial position at least a portion of the cleaning unit is connected to an air introduction path extending from the introduction opening such that the cleaning unit guides a flow of introduced air. A guide edge extends from a lower portion of the cleaning unit toward a bottom of the dust collection space, and a surface of the guide edge facing the inner surface of the housing is inclined.
