Abstract: The present disclosure relates to a cleaner system and a method of controlling the same, the cleaner system including a dust passing hole formed in a coupling part and having an outlet end connected to a flow path part, the dust passing hole having an inlet end configured to communicate with a discharge port of a dust bin of a cleaner when the cleaner is coupled, and a door hingedly coupled to the coupling part and configured to open or close the dust passage hole formed in the coupling part, in which the door is stopped for a particular time or longer when a rotation angle from the discharge port reaches a first opening angle, the door is stopped for a particular time or longer when the rotation angle reaches a second opening angle smaller than the first opening angle, such that dust in the dust bin may be removed without the separate air resistance when the door rotates to the first opening angle in a dust collecting step, and an airflow is rapidly changed in the dust passage hole when the door rotates to the second opening angle in an additional dust collecting step, such that dust attached to a discharge cover may be effectively removed.
