Vacuum with rechargeable battery

1. A vacuum cleaner that has:

a tank that has a bottom and an inlet for receiving debris;

a base;

a motor assembly that is disposed adjacent to the tank and is adapted to draw debris into the tank through inlet;

a battery pack that is disposed, in the base, adjacent to the bottom of the tank;

a connection from the battery pack to the motor assembly that is adapted to carry current between the battery pack and the motor assembly;

at least one battery in the battery pack that supplies power to the motor assembly;

a conductor assembly mounted in the base; and

a cable that extends from the conductor assembly to an outlet receptacle in the base and terminates at an outlet in the outlet receptacle.

2. The apparatus of claim 1 , wherein at least one battery of the battery pack is rechargeable.

3. The apparatus of claim 1 , wherein the connection from the battery pack to the motor assembly includes a cord at least in part connecting the battery pack to the motor assembly.

4. The apparatus of claim 1 , wherein the battery pack is detachably disposed adjacent to the tank.

5. The apparatus of claim 1 , further comprising a battery charger adapted to receive and recharge the battery.

6. The apparatus of claim 1 , further comprising a base disposed under the tank and supporting the tank, the battery being detachably disposed in the base.

7. The apparatus of claim 6 , the base further comprising a dolly and a tray, the battery slidably received in the tray beneath the dolly.

8. The apparatus of claim 1 , further comprising a second cord with a first end extending from the motor assembly and terminating in a plug at a second end, the plug being releasably disposable in the outlet.

9. A vacuum cleaner that is adapted to be powered by a battery pack and has:

a tank that has an inlet opening;

a motor that is disposed in fluid communication with the tank and draws air into the tank through the inlet opening;

a conductor assembly that has an insulating bar and first and second prongs that extend from the insulating bar;

a cord that extends from the insulating bar on a first end, terminates at an outlet on a second end, and at least in part electrically connects the conductor assembly to the motor; and

a tray that is positioned adjacent to the bottom of the tank and the conductor assembly, has a longitudinal axis, and is adapted to slidably receive a battery along its longitudinal axis such that the battery is in electrical communication with the conductor assembly and supplies electrical power to the motor through the cord.

10. The apparatus of claim 9 , further comprising a second cord extending from the motor at a first end and terminating at a plug at the second end, the plug adapted to be received by the outlet.

11. The apparatus of claim 9 , the tray including an outlet receiver adapted to secure the outlet.
