  • the hitting member 100 cannot come into contact with the brush 100 and thus cannot apply force to the debris caught by the brush 50. Therefore, it is desirable that the hitting member 100 be located close to the brush 50.
  • the long debris, such as hair, caught by the brush 50 is rotated in a direction opposite to a rotational direction of the agitator 20 while being wound on the agitator 20. Accordingly, by locating the hitting member 100, which is located rearward of the brush 50 in a rotational direction of the agitator 20, closer to the brush 50 than the other hitting member 100 which is located forward of the brush 50 in the rotational direction of the agitator 20, it may be possible to sufficiently prevent long debris, such as hair, from being firmly wound on the brush 50.
  • a separate hitting member functions to guide dust or debris from a plane to be cleaned by coming into close contact with the cleaning plane, which may ensure efficient removal of the dust or debris from the cleaning plane.
  • the cleaning plane is a carpet pile
  • the hitting member is rotatably coupled to the agitator and is rotated in a direction opposite to a rotational direction of the agitator, it is possible to prevent debris, such as hair, from being wound on the hitting member. Accordingly, a process of removing the debris from the hitting member may be omitted.
  • hitting members and brushes are alternately arranged on the agitator, which results in enhanced cleaning performance because the brushes act to scrape the cleaning plane and the hitting members iteratively come into contact with the cleaning plane.
  • the freely rotatable hitting member may act to separate the hair from the brush.
