Abstract: Disclosed is a cleaner capable of autonomously traveling while performing a mopping task, the cleaner including: a body which defines an exterior appearance of the cleaner; at least one mop module which has at least one mop provided in contact with a floor, and which supports the body against the floor; and a tilt information acquisition unit configured to acquire tilt information of the body in relation to the floor. At least one specific part may comprise the at least one mop, may be a whole or part of the at least one mop module, and may be defined such that the at least one specific part is provided detachable from other parts of the cleaner except for the at least one specific part and that the body tilts in relation to the floor due to gravity while the at least one specific part is separated from the other parts. The cleaner may further comprises a controller which is configured to: based on at least the tilt information, determine satisfaction or unsatisfaction of a predetermined separated condition that is preset to be satisfied when the specific part is separated from the other parts; and, when the detachments condition is satisfied, control a predetermined mop separation error response operation.
