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: A cleaner includes a rotation prevention assembly which selectively fixes a first rotation member that rotates the body about a first rotational axis and a second rotation member that rotates the body about a second rotational axis. The rotation prevention assembly includes: a catching groove in the first rotation member; and a fixing member rotatably coupled to the second rotation member and inserted into the catching groove. The fixing member extends in the direction of gravity and freely rotates. When the angle between the second rotational axis and the ground is greater than a predetermined angle, the fixing member is caught by the catching groove, preventing rolling, and yawing allows the cleaner to be operated. When the angle between the second rotational axis and the ground is less than a predetermined angle, the fixing member is not inserted into and caught by the catching groove, and rolling prioritizes over yawing.
