Abstract: A cleaner may include a main body configured to be ascendable and descendable with respect to a suspension assembly provided to absorb shocks applied to a wheel assembly, thereby enabling the suspension assembly to continuously absorb shocks even when the height of the main body is adjusted. The cleaner may further include a charging terminal configured to connect to an external docking device to charge the cleaner and provided on a bottom surface of the main body, a drive assembly including a wheel assembly to drive the main body, a height adjuster coupled to the main body to ascend or descend together with the main body and mounted to the drive assembly so as to be ascendable and descendable, and a controller to ascend the height adjuster and raise the main body when the main body is set to be docked with the docking device.
