Vacuum cleaner station, vacuum cleaner system, and control method therefor

A cleaner system including:

• a cleaner comprising a suction part having a suction flow path through which air flows, a dust separating part configured to separate dust from the air, a main body having a suction motor configured to generate a suction force for sucking the air along the suction part, and a dust bin configured to store the dust separated by the dust separating part;
• and
• a cleaner station comprising a coupling part including a dust bin guide surface to which an outer peripheral surface of the dust bin is coupled, a dust collecting part disposed below the coupling part and configured to capture dust in the dust bin, a dust collecting motor disposed below the dust collecting part and configured to generate a suction force for sucking the dust in the dust bin to the dust collecting part, and a housing having the dust collecting part and the dust collecting motor therein,
• wherein the cleaner further comprises:
• a prefilter disposed in a flow path configured to connect the dust separating part and the suction motor, the prefilter being configured to filter out foreign substances contained in the air;
• and
• a differential pressure sensor configured to detect a differential pressure between air before passing through the prefilter and air after passing through the prefilter, and
• wherein the dust collecting motor operates when the cleaner is coupled to the cleaner station when the differential pressure detected by the differential pressure sensor is equal to or higher than a preset reference differential pressure.
