Abstract: Provided is a vacuum cleaner including a motor configured to generate a suction force, an inverter configured to convert a DC power of a DC terminal capacitor into an AC power to output to the motor, and a controller configured to apply a control signal of the inverter to drive the motor, in which the controller is further configured to detect an event while the motor is driving, and generate the control signal to generate operation noise of the motor corresponding to the detected event. According to example embodiments of the present specification, it is possible to provide information to a user without a separate element by controlling the driving pattern of the motor in the vacuum cleaner.
