Abstract
An upright vacuum cleaner includes a cleaning head having a suction opening defined along a bottom thereof, a handle assembly connected to the cleaning head, a motor, and a blower connected to the motor and operable to generate suction through the suction opening upon operation of the motor. The vacuum cleaner further includes an electrical connection interface selectively connectable to a direct current (DC) power source and an alternating current (AC) power source. The electrical connection interface is electrically connectable to the motor via an electrical path such that an AC current is supplied to the motor when the AC power source is connected to the electrical connection interface, and a DC current is supplied to the motor when the DC power source is connected to the electrical connection interface.
