Abstract: The present disclosure relates controlling a robot cleaner that moves based on a rotation of a spin mop. The controlling the robot cleaner includes determining a control command; operating the spin mop and performing a reference motion by the robot cleaner; detecting a movement of the robot cleaner which performs a reference motion by a motion detection sensor; and controlling travel of the robot cleaner to achieve the control command.

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. The controller is configured to determine 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, and determine that a specific area of the floor is a contaminated area when there is a change in the position and a change in the load current.

Abstract: A washing apparatus washes a cleaner having a mop unit formed at a lower portion thereof. The washing apparatus includes a tray configured to form a space to receive the cleaner and washing water. A washing unit is disposed at a lower portion of the inside of the tray in contact with the mop unit. The washing unit includes a first spinning mop protrusion line configured to protrude upwardly, an upper end of the first spinning mop protrusion line being inclined downwardly in a first direction.

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.
