Kind Code:
A1
Abstract:
The present invention relates to a cleaner and a cleaner system, and comprises: a dust barrel; a suction portion for guiding air into the dust barrel; a suction motor for generating suction power such that air is suctioned through the suction portion; a cyclone portion for generating a cyclone flow of air suctioned through the suction portion, thereby separating dust from the air; and a filter portion for filtering air discharged from the cyclone portion. The filter portion comprises: a filter body disposed inside the dust barrel such that the cyclone flow is formed along the outer periphery thereof; and a filter hole for guiding air into the filter body. The present invention is advantageous in that air flows into the filter body through the filter hole while being inclined in the opposite direction to the direction in which the cyclone flow formed near the entrance of the filter hole propagates, thereby preventing hair from getting stuck in the filter hole.
