摘要： Disclosed herein is a cleaning robot capable of allowing a driving apparatus to move along a cleaning apparatus when the cleaning apparatus is separated from the driving apparatus, and a controlling method thereof. In addition, a cleaning robot having a driving apparatus capable of storing a position from which a cleaning apparatus is separated when the cleaning apparatus is separated from the driving apparatus, and capable of moving to the stored position when the cleaning apparatus is mounted to the driving apparatus, and a controlling method thereof. The cleaning robot includes a driving apparatus provided with a mounting groove configured to allow a cleaning apparatus to be removably mounted, and the cleaning apparatus removably mounted to the mounting groove. When the cleaning apparatus is separated from the mounting groove, the driving apparatus stores a position of the driving apparatus upon the separation of the cleaning apparatus and when the cleaning apparatus is mounted to the mounting groove, the driving apparatus moves to the stored position.

摘要： A cleaner includes a first extension pipe connected to a suction portion contacting a surface to be cleaned, and a second extension pipe coupled to a cleaner body having a driver generating suction force, and rotatably coupled to the first extension pipe. The first and second extension pipes operate in a first arrangement configured to allow the second extension pipe to be arranged in a longitudinal direction of the first extension pipe, and a second arrangement configured to allow the second extension pipe to rotate in a first direction from the first arrangement such that the first extension pipe and the second extension pipe are arranged to face each other. Such configuration enables a user to increase cleaning efficiency.
