    Abstract: The present disclosure relates to a cleaner station and a cleaner system, and a method for controlling the cleaner system. According to an embodiment, by driving the suction motor of the cleaner after the drive of the dust collecting motor of the cleaner station is finished, it is possible to suck back, into the dust bin, foreign substances such as strands of hair etc. which stuck and remain in an open end of the dust bin even after collecting the dust in the dust bin so that the foreign substances can be removed.

    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.

    Abstract: The present disclosure relates to a cleaner system and a method of controlling the same, the cleaner system including a cleaner including a dust bin configured to collect dust, and a cleaner station to which the cleaner is coupled, in which the cleaner includes a suction motor configured to generate a suction force to the dust bin, a suction force of the suction motor is changed at least one or more times, and a flow direction of the dust in a flow path part connected to the dust bin is changed reversely at least one or more times, such that when debris firmly caught by the dust bin has strong resistance against an airflow in one direction, an airflow may be applied in the opposite direction to effectively remove the debris.

    Abstract: Disclosed is a cleaner including a first body having a cleaning unit, a second body configured to move autonomously, and a sensing module including at least one first sensor disposed on the first body and at least one second sensor disposed on the second body, the sensing module sensing a variable distance between the first sensor and the second sensor. Any one of a number of the at least one first sensor and a number of the at least one second sensor is two or more, and the sensing module senses two variable distances by two different combinations of one first sensor and one second sensor. The cleaner further includes a controller configured to control the second body to follow the first body based on the two variable distances.
