Abstract: The present disclosure relates to a cleaner. Since the cleaner includes: a pitch member configured to rotate the main body about the pitch axis; a yaw member configured to rotate the main body about the yaw axis; and a roll member configured to rotate the main body about the roll axis, and limits a rotation of the roll member when the main body is in a first location, and allows a rotation of the roll member when the main body is in a second location, the cleaner secures excellent operability when the cleaner is in the first location which is higher, and excellent straightness when the cleaner is in the second location which is lower.

Abstract: A cleaner is disclosed. A dust storage container according to an embodiment of the present invention includes a winding member. The winding member rotates in the dust storage container to wind debris having a shape which is thin, long, and compressible, such as fur of an animal or fiber introduced into the dust storage container. Accordingly, a space occupied by the debris in the form of fur or fiber in the dust storage container is reduced. Therefore, the dust storage container can receive a large amount of debris so as to increase an operable time of the cleaner. Consequently, the convenience of a user can be improved.
