Abstract
A vacuum cleaner capable of drawing different current levels in vacuum and blower modes is disclosed. The vacuum cleaner comprises at least one electric motor and an impeller disposed in an impeller housing, the impeller driven by the at least one electric motor. A receptacle has an inlet and an orifice in fluid communication with the impeller housing, wherein the impeller creates a low pressure area in the receptacle thereby drawing air into the inlet. An outlet is in air flow communication with the impeller housing, wherein air from the impeller is expelled through the outlet. A switch is associated with the outlet, wherein the switch has a first position in which a first current may be drawn by the at least one motor and a second position in which a second current, less than the first current, may be drawn by the at least one motor. A device is removably attached to the outlet for directing air.
