Abstract
A cleaner includes a suction unit guiding air and dust, a main body including a first cyclone unit separating the air and the dust, which are suctioned through the suction unit, from each other and a second cyclone unit separating the dust from the air discharged from the first cyclone unit, and a guide unit disposed in the main body to partition a first dust storage part, in which the dust separated in the first cyclone unit is stored, and a second dust storage part, in which the dust separated in the second cyclone unit is stored, from each other. The guide unit is separably coupled to the main body, and when the guide unit is separated from the main body, a dust discharge part of the second cyclone unit is exposed to the outside.
