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 which includes: a dustbin having a slit formed on one side thereof; a compression lever housing disposed on an outside of the slit and mounted to the dustbin; a compression plate disposed on an inside of the dustbin and configured to ascend in a direction in which the slit extends; and a sealer disposed in the compression lever housing, coming in close contact with the slit, and extending along the slit. Therefore, the cleaner according to the present disclosure may prevent a problem that is likely to occur during an operation of the compression lever assembly because of trapped dust, and can be maintained in a cleaner state as the user may easily separate the cleaner by assemblies to sterilize the parts.

Abstract: The present disclosure relates to a cleaner including: a cyclone part of which one side has an inlet formed therein and the other side has an outlet formed therein; a housing which is connected to the cyclone part; a motor unit which is disposed in the housing, of which one side has a suction inlet formed therein that sucks air from the cyclone part, and of which the other side has a discharge port formed therein that discharges the air to the outside; and a filter which is disposed in the housing, of which one side covers the outlet of the cyclone part, and of which the other side covers the suction inlet of the motor unit. The filter includes: a first surface extending from a front to a left rear thereof; and a second surface extending from a front to a right rear thereof. Accordingly, it is possible to reduce pressure loss of the air that has passed through the filter, and a filtration performance can be obtained. Also, dust bins of various sizes can be variably installed.
