19. A vacuum cleaner comprising:
-
a cleaner body including a suction motor, the suction motor being configured to generate suction force; and a suction part in communication with the cleaner body and configured to suction air and dust, wherein the cleaner body further includes; a main body, wheels for moving the main body, and a battery that is detachably provided at a back side of the main body and configured to supply power to the main body, wherein the main body is configured to rotate about a rotation center of the wheels, wherein, based on the battery being detached from the cleaner body, a center of gravity of the main body is located forward of a vertical extension line passing through the rotation center of the wheels, wherein, based on the battery being attached to the cleaner body, the center of gravity of the cleaner body is located rearward of the vertical extension line passing through the rotation center of the wheels, wherein the cleaner body is configured to, based on the cleaner body being moved in a forward traveling direction by the wheels, rotate about the rotation center of the wheels in a first direction such that the battery becomes farther from ground based on the cleaner body travelling in the forward traveling direction as compared to the cleaner body being stationary, and wherein, based on the battery being attached to the cleaner body, a center of gravity of the battery is located vertically lower than the rotation center of the wheels. - View Dependent Claims (20, 21)
