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.
