Abstract: A moving robot is provided. The moving robot includes a body, first and second driving wheels configured to move the body, first and second caster wheels installed movably, first and second sensors configured to respectively detect a rotation angle of the first caster wheel and a rotation angle of the second caster wheel with respect to a predetermined direction axis, and a controller configured to control driving of a driving wheel according to the rotation angles. The controller calculates an average rotation angle by using the rotation angles detected by the first and second sensors and controls driving of the driving wheel by using the calculated average rotation angle.

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.
