CLEANER AND DRIVING METHOD THEREOF

摘要

A cleaner is provided to be operated through enough power by a commercial alternating current voltage and a voltage of a battery. A cleaner contains a motor(20) of a low resistance mode for rotating a fan(22) for collecting dust, a voltage conversion portion converting a commercial alternating current voltage from a battery(12) power source into a direct current voltage and a motor driver(18) pressuring selectively a voltage of a battery and a direct current voltage operating a motor to a voltage pressured selectively according to an input state of the commercial alternating current voltage.
