Abstract

A mobile unit, such as a cart, for transporting a portable vacuum system is disclosed. The cart may have one or more compartments and areas for storing cleaning supplies and the like. The unit may also have a debris containment compartment for receiving and storing debris collected by the portable vacuum system. Additionally, a battery charging circuit may connect one or more batteries carried on the cart for selectively charging the batteries.

Claims

1. A mobile unit for a portable vacuum system, comprising:

a cart having a plurality of wheels to enable the cart to be moved;

at least one debris containment compartment in said cart; and

at least one portable vacuum system docking station on said cart;

wherein said at least one debris containment compartment and said at least one portable vacuum system docking station are connected to each other.

2. The mobile unit of claim 1, wherein said cart has a plurality of storage bins for selectively receiving cleaning supplies.

3. The mobile unit of claim 1, wherein said cart has at least one handle, said handle can be manually grasped for moving said cart on said plurality of wheels.

4. The mobile unit of claim 1, wherein said docking station has a slidable door.

5. The mobile unit of claim 4, wherein said docking station door provides access to an interior portion of said debris containment compartment.

6. The mobile unit of claim 1, wherein said docking station opens toward one side of the top portion of said cart.

7. The mobile unit of claim 4, wherein said slidable door has at least one handle to manually pull and to push said slidable door open and closed, respectively.

8. The mobile unit of claim 1, wherein said debris containment compartment of said cart is selectively removable from a side of said cart.

9. A mobile unit for a portable vacuum system, comprising:

a cart having a plurality of wheels to enable the cart to be moved;

a plurality of battery charging receptacles located on said cart;

at least one battery charging circuit electrically connected to said plurality of battery charging receptacles; and

at least one portable vacuum system station on said cart.

10. The mobile unit of claim 9, wherein said battery charging circuit comprises at least one charging circuit, a logic circuit, and said plurality of battery charging receptacles, wherein said charging circuit provides a battery recharging voltage to said logic circuit, which provides a recharging voltage to one or more batteries located in said battery charging receptacles until said logic circuit determines that said one or more batteries is fully charged.

11. The mobile unit of claim 9, wherein said plurality of battery charging receptacles are located on a top portion of said cart.

12. The mobile unit of claim 9, wherein said plurality of battery charging receptacles are complementary shaped recesses to the shape of said one or more batteries.

13. The mobile unit of claim 9, wherein said at least one portable vacuum station is a shelf located on a lower, open portion of said cart.

14. A mobile unit for a portable vacuum system, comprising:

a cart having a plurality of wheels to enable said cart to be moved;

at least one debris containment compartment in said cart;

a plurality of battery charging receptacles on said cart; and

at least one battery charging circuit electrically connected to said plurality of battery charging receptacles.

15. The mobile unit of claim 14, wherein said cart has at least one portable vacuum system docking station connected to said at least one debris containment compartment.

16. The mobile unit of claim 14, wherein said battery charging circuit comprises at least one charging circuit, a logic circuit, and said plurality of battery charging receptacles, wherein said charging circuit provides a battery recharging voltage to said logic circuit, which provides a recharging voltage to one or more batteries located in said battery charging receptacles until said logic circuit determines that said one or more batteries is fully charged.

17. The mobile unit of claim 15, wherein said portable vacuum system docking station has at least one door for providing selective access to an interior portion of said debris containment compartment.
