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.
