A cleaning system comprising: a vacuum cleaner comprising a dust collecting chamber (20, 50) capable of collecting foreign substances; and a dust collecting station (100, 400) connectable to the vacuum cleaner and configured to remove the foreign substances collected in the dust collecting chamber, wherein the dust collecting station comprises: a seating portion comprising an opening configured to communicate with an inside of the dust collecting chamber, wherein the dust collecting chamber is configured to be seated on the seating portion while the vacuum cleaner and the dust collecting station are connected; a suction device (130, 430) configured to generate a suction airflow to discharge the foreign substances from the dust collecting chamber through the opening of the seating portion, wherein a flow path (132, 151, 171, 181, 441) is formed between the opening of the seating portion and the suction device while the suction airflow is generated; a collecting portion arranged between the opening of the seating portion and the suction device, the collecting portion being configured to collect the foreign substances from the dust collecting chamber through the opening of the seating portion; and a flow path control device (150, 150', 170, 180, 220) comprising a flow path cover (152, 172, 182, 223) configured to block at least a portion of the flow path while the vacuum cleaner and the dust collecting station are connected and the suction device generates the suction airflow for discharging the foreign substances from the dust collecting chamber, and wherein the flow path control device is configured to move a position of the flow path cover to block at least the portion of the flow path such that the suction airflow within the dust collecting chamber changes based on the position of the flow path cover during operation of the suction device. a vacuum cleaner comprising a dust collecting chamber (20, 50) capable of collecting foreign substances;
