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 charging apparatus for a mobile robot, including a caster guide for guiding a charging terminal, provided for the charging apparatus, and a corresponding terminal, corresponding to the charging terminal, to readily come into contact with each other, in which by determining a contact position of the two terminals in a longitudinal direction using a first guide surface to a third guide surface, and by determining a contact position of the two terminals in a traverse direction using a caster guide having a wide rear portion and a narrow front portion, the charging apparatus for the mobile robot may guide the two terminals to vertically overlap with each other.

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.
