1. A cleaner comprising:
a suction unit guiding air and dust;
a main body comprising (i) a first cyclone unit separating the air and the dust, which are suctioned through the suction unit, from each other, (ii) a second cyclone unit separating the dust from the air discharged from the first cyclone unit, and (iii) a dust container; 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 received, and a second dust storage part, in which the dust separated in the second cyclone unit is received, from each other,
wherein the guide unit is detachably coupled to the main body and comprises:
a filter part that is configured to separate the air from the dust in the first cyclone unit while the air flows to the second cyclone unit and that surrounds the second cyclone unit,
a storage unit connected to a lower portion of the filter part and defining the second dust storage part in the main body, and
a cleaning part extending from an upper end of the filter part to an inner circumferential surface of the dust container,
wherein, based on the guide unit being separated downward and spaced apart from the main body, a dust discharge part of the second cyclone unit is exposed to an outside of the main body of the cleaner to enable emptying of foreign substances within the dust container.
