Abstract: A robot cleaner includes a cleaning module having a left spin-mop and a right spin-mop configured to contact a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from above. The robot cleaner also includes a controller that manages the cleaning module such that, when the robot cleaner travels in a zigzag pattern including a first travel, during which the robot cleaner travels straight in a first direction, and a second travel, during which the robot cleaner travels straight in a second direction, which is opposite the first direction, a movement trajectory of the left spin-mop or the right spin-mop during the second travel overlaps a movement trajectory of the left spin-mop and a movement trajectory of the right spin-mop during the first travel.

Abstract: A robot cleaner includes a main body forming an exterior of the robot cleaner, a driving unit configured to move the main body, a cleaning module coupled to the main body and configured to suction dust from a traveling surface, and a dust collector coupled to the main body and configured to collect the dust suctioned by the cleaning module. The cleaning module includes a cleaning module housing that defines an exterior of the cleaning module that is coupled to the main body. A mopping unit is rotatably coupled in the cleaning module housing. The mopping unit is configured to accommodate water therein and clean the traveling surface. A mop is detachably coupled to the mopping unit, and a pump is disposed in the mopping unit. The pump is configured to guide water to the mop as the main body moves.

Abstract: A robot cleaner is provided, including a main body forming a robot cleaner exterior, a driver coupled to the main body to move the main body, a cleaning module coupled to the main body to suck dust from a traveling surface, a dust collector removing dust from air suctioned through the cleaning module, and a wet-mop module coupled to the main body to mop the traveling surface, wherein the wet-mop module includes a wet-mop module housing surrounding at least a portion of the main body and accommodating water in an internal space, a wet-mop module wheel disposed in the wet-mop module housing, a mop disposed between the wet-mop module housing and the traveling surface, and a wet-mop pump connected to the wet-mop module wheel to supply water to the mop in response to rotation of the wet-mop module wheel. Mopping may be performed without applying physical force of a person.
