Disclosed are a nozzle unit and a robot cleaner including same. The nozzle unit according to various embodiments of the present invention comprises a main brush for collecting waste such as hair and a sub brush for separating the waste such as hair attached to the main brush. The sub brush is provided with various members according to the embodiment, and separates the waste such as hair attached to the main brush. Thus, the waste such as hair can be easily collected, separated, and captured. Accordingly, user convenience can be enhanced.

A nozzle of a cleaner includes a nozzle body, a rotation cleaning part having a rotation plate to which a rag is attached, a driving device provided in the nozzle body, a water tank, a water supply passage, and a water adjuster of which at least a portion is mounted on the nozzle body at a rear side thereof so as to be exposed to a rear surface or a top surface of the nozzle body. A user standing on the same floor surface as the nozzle body may manipulate the water adjuster by using his or her foot. The water adjuster can adjust an on/off operation and a rotational speed (e.g., rpm) of the pump motor.

A nozzle for a cleaner includes a nozzle housing having a suction flow path through which air containing dust flows, a first rotation cleaning unit and a second rotation cleaning unit located on a bottom side of the nozzle housing, the first rotation cleaning unit and the second rotation cleaning unit being spaced apart from each other in a left-right direction of the nozzle housing, each of the first rotation cleaning unit and the second rotation cleaning unit having a rotation plate, a driving device located in the nozzle housing, and a water tank located on the nozzle housing, the water tank being configured to store water to be supplied to the first rotation cleaning unit and the second rotation cleaning unit. The water tank includes a first chamber, and a second chamber spaced apart from the first chamber in the left-right direction of the nozzle housing.

A floor cleaner including a base that includes a suction inlet, a brushroll chamber, and brushroll. The brushroll chamber includes a brushroll, an endcap, a tab extending from the endcap, a driven end and a non-driven end. The endcap includes the tab extending from the endcap. The tab is movable between an unfolded and a folded position. Upward movement of the tab in the unfolded position removes the brushroll from the base.

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.

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.

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.

The present disclosure provides a cleaning brush and an intelligent cleaning device. The cleaning brush includes a shaft rod, a cylindrical member and at least one end member. The shaft rod is provided with two first ends which are opposite in an axial direction; the cylindrical member coaxially sleeves the shaft rod and is provided with two second ends which are opposite in an axial direction, and a brush piece is arranged on an outer surface of the cylindrical member; the at least one end member is installed on at least one of the first ends, and the end member is provided with a blocking structure for preventing an entanglement from excessively extending away from the cleaning brush; the end member and the first end are provided with installation structures respectively matching each other; and the second end of the cylindrical member, which corresponds to the end member, covers at least a portion of the end member.

A floor cleaner including a base that includes a suction inlet, a brushroll chamber, and brushroll. The brushroll chamber includes a brushroll, an endcap, a tab extending from the endcap, a driven end and a non-driven end. The endcap includes the tab extending from the endcap. The tab is movable between an unfolded and a folded position. Upward movement of the tab in the unfolded position removes the brushroll from the base.
