Abstract: A mobile robot includes a body and a mop module with left and right rotating plates rotatably installed on the body and each including a water supply space. The mobile robot also includes a water distribution module for providing water to the water supply spaces of the left and right rotating plates, and a water supply module for supplying water to the water distribution module. The water distribution module includes a water-supply counterpart portion connected to the water supply module and configured to receive water. Left and right water supply distribution pipes are connected to the water-supply counterpart portion to supply water to the water supply spaces of the left and right rotating plates, wherein the length of the left and right water distribution pipes are the same.

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.

Abstract: A robot cleaner includes a rolling cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while in contact with a floor, a sensor unit, and a controller configured to detect a change in position of the robot cleaner and a change in load current of a motor connected to the rolling member based on data detected by the sensor unit. When there is a change in position and a change in load current, a specific area of a floor is determined to be a contaminated area.
