Abstract: A vacuum cleaner includes a cleaner main body and a brush-less direct current (BLDC) motor that generates a suction force. A suction unit is in communication with the cleaner main body and sucks air and dust, and a battery provides power for the motor. An inverter supplies power of the battery to the motor, and a controller controls an operation of the motor. The controller determines a status of a floor and controls an operation of the motor based on the determined status of the floor.
