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.
