Abstract: The present disclosure relates to a cleaner station including: a collector which is attachably and detachably coupled to the inside of a housing and collects dust within a dust bin of a cleaner; and a dust collection motor which is received within the housing, is disposed below the collector, and generates a suction force for sucking the dust within the dust bin. The collector includes: a collector body in which dust is collected; a collector cover which is coupled to a top of the collector body and comprises a dust inlet formed therein into which air containing dust is introduced; and a collector flow path which is disposed within the collector body and guides the air which has passed through the dust separator to the dust collection motor. Accordingly, the bin-type collector is applied and the flow path through which the dust flows can be formed in a direction perpendicular to the ground. Also, a flow path is provided within the collector, so that a space for storing the dust can be maximized.
