Abstract: A vacuum cleaner includes a body having a space that allows air to flow therethrough. The vacuum cleaner also includes a suction inlet configured to introduce the air into the body. Further, the vacuum cleaner includes a suction motor provided in the body. The vacuum cleaner includes a dust separation module provided in the body. The dust separation module is arranged between the suction inlet and the suction motor. The dust separation module separates foreign substances from the air. The vacuum cleaner includes an exhaust module that discharges the air passing through the suction motor from the body. The exhaust module includes an exhaust filter comprising a photocatalyst. Further, the vacuum cleaner includes a lighting module that radiates light toward the exhaust filter. The vacuum cleaner includes a battery supplying electrical energy for the operation of the vacuum cleaner and a controller configured that controls operations of the vacuum cleaner.

Abstract: A vacuum cleaner includes a body having a space that allows air to flow therethrough. The vacuum cleaner includes a suction inlet that introduces the air into the body and a first cyclone in the body. The first cyclone separates foreign substances from the air introduced into the suction inlet. The vacuum cleaner includes a dust separation module having a filter unit that separates foreign substances from the air introduced from the first cyclone. The dust separation module also includes a second cyclone arranged within and separated from the filter unit. The second cyclone includes a cyclone base, a storage unit arranged adjacent to a lower portion of the second cyclone, and a cyclone array coupled to the cyclone base. The cyclone array allows the air to pass through an upper portion of the second cyclone and discharge the foreign substances collected by the second cyclone to the storage 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.
