ABSTRACT:
A cleaner that can be operated at motive force of sufficient strength by using a battery voltage as well as by using a AC voltage. The cleaner uses a low-resistance-mode motor to rotate a collecting fan. The low-resistance-mode motor is driven by a motor driver. The motor driver drops a DC voltage converted from the AC voltage, depending on whether the AC voltage is received. Depending on whether the AC voltage is received, the motor driver drives the low-resistance-mode motor using one of the battery voltage and the dropped voltage.
