Abstract: Disclosed is a cleaner station including: a suction flow path having an inlet end communicating with a dust bin of a cleaner; and a dust collecting part connected to an outlet end of the suction flow path and collecting dust inside the dust bin of the cleaner. The dust collecting part includes: a dust collecting body having a dust inlet connected to the outlet end of the suction flow path; an inlet tube extending inward from a circumferential surface of the dust inlet and having an end forming a curvature circle with a specific curvature when viewed from one side; and an inlet tube cover disposed at the end of the inlet tube and opening and closing the inlet tube. Accordingly, by closing the inlet tube when the dust collecting part is separated from the cleaner station, the cleaner station may prevent dust from scattering, winged insects from escaping or odors from spreading.
