Abstract: Disclosed are a nozzle unit, a robot cleaner including same, and a control method therefor. The nozzle unit according to an embodiment of the present invention comprises a plurality of brushes that rotate in different directions. One of the plurality of brushes rotates such that waste such as hair attaches and collects thereon. Another one of the plurality of brushes rotates such that the attached waste such as hair becomes separated. The above processes are performed simultaneously. Accordingly, waste such as hair present on a floor surface can be easily collected and separated. Consequently, user convenience can be enhanced.

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.

Abstract: A nozzle part and a robot cleaner including same are disclosed. A nozzle part according to various embodiments of the present invention comprises: a brush for collecting waste such as hair; and a removing member for removing the waste, such as hair, that is stuck to the brush. The removing member more quickly rotates than the brush in the same direction to remove the waste, such as hair, that is stuck to the brush. Therefore, the waste such as hair can be easily collected, removed and captured. Thus, user convenience can be improved.

Abstract: Disclosed is a cleaner. A dust accommodation container according to an embodiment of the present invention comprises a winding member. The winding member rotates inside the dust accommodation container and winds thin, long compressible waste, such as animal hair or fibers, which have flowed into the dust accommodation container. Accordingly, the space occupied inside the dust accommodation container by waste such as hair or fibers is reduced. Thus, the dust accommodation container can accommodate a larger amount of waste, and the operable time of the cleaner is greater. Consequently, user convenience can be enhanced.

Abstract: Disclosed are a conversion member and an electric cleaner. The conversion member according to embodiments disclosed herein may be detachably coupled to a handle included in a main body and a pipe. Then, the main body may be connected to an intake port located at the lowest position, and the pipe may be connected to an extension handle, allowing the main body to be located at a lower position facing the intake port. Thus, the electric cleaner may have a low center of gravity. Further, when the conversion member is detached, the pipe may be located between the main body and the intake port to be connected to the main body and the intake port, respectively. Accordingly, the main body may be located at an upper position directed away from the intake port, allowing the electric cleaner to have a high center of gravity.

Abstract: Disclosed is a cleaner. A cleaner according to an embodiment of the present invention comprises: a brush; and a removal member that is positioned adjacent to the brush. The brush is rotated to collect garbage, such as hair, located on a floor surface. The collected garbage, such as hair, may be pushed by the removal member and separated from the brush. The garbage, such as hair, separated from the brush may pass through a nozzle housing and may then be collected in a dust bin. Therefore, the garbage, such as hair, attached to the brush can be easily separated and collected without a separate removal process. Accordingly, user convenience can be improved.
