Abstract: A cleaner is disclosed. The cleaner according to an embodiment of the present invention comprises a winding member. The winding member is rotated in the cleaner to wind up thereon long and thin trash that can be compressed, such as animal hair, fibers, etc., which is introduced in a dust accommodation container. An attachable/detachable frame is accommodated in the cleaner to be detachable. The winding member has a base which has the largest diameter and is inserted and coupled to a winding member coupling portion of the attachable/detachable frame. Trash such as hair, fibers, etc. wound on the winding member is placed on a coupling plate that is located above the winding member coupling portion. Therefore, when the attachable/detachable frame is detached, the trash in the form of hair or fibers wound on the winding member is also discharged out of the dust accommodation frame along with the attachable/detachable frame. Accordingly, user convenience can be improved.
