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: The present invention relates to a wet duster module of a cleaner for sucking or wiping dust or foreign substance in an area to be cleaned by discharging water to a duster. The wet duster module of the cleaner according to the embodiment of the present disclosure can cause forced convection of the air in the inner space through the passage hole that communicates the suction passage and the inner space of the module housing without having a separate cooling module. Therefore, the cooling efficiency of the driving unit disposed in the inner space can be increased. Accordingly, this can not only contribute to the miniaturization of the wet duster module but also adopt the drive motor with higher output, thereby enabling high performance of the wet duster module.
