ABSTRACT:
A vacuum apparatus includes a housing that includes a vacuum assembly with a base. A rechargeable battery is mounted within the vacuum assembly and is electrically coupled to the blower of the vacuum assembly which creates suction through the base when the blower is turned on. A plurality of first mating charge contacts is mounted on the housing and are electrically coupled to the battery. The first mating charge contacts are engageable with second mating charge contacts mounted in an upper surface of a charging station. A power cord is electrically coupled to the second mating charge contacts to supply power to the second mating charge contacts. The battery is charged when the first and second mating charge contacts abut each other and the power cord is plugged into an electrical power source.
