Abstract: A mobile cleaner includes a body, a mop module, and a sweep module. The mop module includes a pair of spin mops configured to rotate and mop a surface. The sweep module is configured to sweep up foreign material on the surface using a rotating agitator. The sweep module includes a dust housing, the agitator, and a wheel assembly. The wheel assembly is configured to support the dust housing on the surface and includes a wheel body that is movable in a vertical direction. A cliff sensor is configured to detect movement of the wheel body.

Abstract: The present disclosure relates to a cleaner station configured to be coupled to a cleaner to capture dust in a dust bin of the cleaner, and a cleaner station according to an embodiment of the present disclosure includes a station main body to which a cleaner is configured to be coupled, the station main body including a dust collecting motor configured to operate to provide a suction force in a dust bin of the cleaner, and a suction flow path through which air discharged from the inside of the dust bin flows, a dust collecting container disposed above the station main body and configured to capture dust flowing together with the air, an impactor flow path tube disposed outside and above the dust collecting container and configured to provide a flow path through which the air introduced through the suction flow path flows, and a discharge air moving part configured to provide a space in which discharge air, from which the dust is separated, is introduced and flows after being discharged from the impactor flow path tube, in which a direction in which the dust moves in the impactor flow path tube is different from a direction in which the suction force is applied to the discharge air discharged from the impactor flow path tube.

Abstract: A cleaner includes a body including an insertion slot facing a floor and an installation space inside the body. The cleaner includes a dust housing detachably connected to the body. The dust housing includes a collection opening surface and a storage space that stores foreign substances collected through the collection opening surface. The cleaner has an agitator rotatably connected to the dust housing and exposed through the collection opening surface. The cleaner also includes a driving apparatus that rotates a driving coupler, which drives a driven coupler coupled to the agitator. The cleaner includes a lever located on either the driving coupler or the driven coupler. The lever selectively attaches or separates the driving coupler and the driven coupler. Manipulating the lever separates the driving coupler and the driven coupler and allows the sweep module including the agitator to be removed through the insertion slot in the body.
