Abstract
A vacuum cleaner is provided which includes a cleaner body in which a ultraviolet (UV) irradiation unit is mounted in a dust receptacle mounting unit, a dust receptacle detachably mounted in the dust receptacle mounting unit, the dust receptacle comprising a UV transmission window formed in a position facing the UV irradiation unit, and a switching device mounted in the dust receptacle mounting unit to switch power applied to the UV irradiation unit according to whether the dust receptacle is mounted. Accordingly, power is applied to a UV lamp only when the dust receptacle is mounted in the vacuum cleaner, so there is no risk that a user is exposed to UV rays emitted from the UV lamp when the user separates the dust receptacle from the vacuum cleaner.
