ABSTRACT:
A cleaner that can automatically respond to a change in an AC voltage and a voltage of a battery. In the motor, a motor for rotating a collecting fan is driven by a motor driver. The motor driver drives the motor using a voltage from a voltage selector. The voltage selector switches between a low-level voltage of the battery and a high-level voltage derived from the AC voltage to be supplied to the motor driver.
