Abstract: Provided is a vacuum cleaner. The vacuum cleaner includes a cleaner body including a moving device for moving, a suction device connected to the cleaner body to suction dusts and air and guide the suctioned dusts and air to the cleaner body, the suction device including a handle, a detection device for detecting a distance between the handle and the cleaner body, and a controller determining whether movement of cleaner body is necessary on the basis of the distance between the cleaner body and the handle, the controller controlling the moving device when the movement of the cleaner body is necessary. The controller controls the moving device to allow the cleaner body to avoid an obstacle when it is determined that an operation for avoiding the obstacle is necessary while the moving device operates.

Abstract: A vacuum cleaner may include a cleaner body having a suction motor and a suctioning portion configured to be in communication with the cleaner body and to suction air and dust. One of a battery assembly having a battery or a cord reel assembly having a power cord may be installed in the cleaner body. The vacuum cleaner may also include a controller to control the suction motor by modifying a pulse width modulation (PWM) duty cycle of an inverter providing power to the suction motor based on whether the battery assembly or the cord reel assembly is installed in the cleaner body.
