Abstract
A vacuum cleaner includes a suction inlet, a motor, and an impeller connected to the motor and operable to generate suction through the suction inlet upon operation of the motor. The vacuum cleaner further includes a power connector mounted to the vacuum cleaner and selectively connectable to a direct current (DC) power source and an alternating current (AC) power source. The power connector includes external terminals accessible from an exterior of the vacuum cleaner. The external terminals are configured for removable mechanical connection to each of the DC power source and an AC power supply cord such that the DC power source and the AC power supply cord are selectively and mechanically connectable to the same external power connector terminals.
