Abstract

A vacuum cleaner, includes a first compartment for receiving air-entrained dust particles drawn therein by a fan, and a second compartment for receiving debris delivered thereto by a motor-driven bristle bar past which the fan draws air.

Claims

1. A vacuum cleaner, comprising:

a first compartment receiving air-entrained dust particles drawn therein by a fan, and

a second compartment receiving debris delivered thereto by a motor-driven bristle bar past which the fan draws air.

2. The vacuum cleaner of claim 1, wherein the first compartment is located within a suction housing and the second compartment is located in a floor-traversing cleaning head that is pivotally interconnected with the suction housing.

3. The vacuum cleaner of claim 2, wherein the bristle bar is rotatably mounted within the cleaning head, and further comprising a deflector plate for deflecting the debris from the bristle bar into the second compartment.

4. The vacuum cleaner of claim 2, further comprising a first electric motor housed within the suction housing and wherein the fan is driven by the first electric motor.

5. The vacuum cleaner of claim 2, further comprising a second electric motor housed within the cleaning head and wherein the bristle bar is driven to rotate by the second electric motor.

6. The vacuum cleaner of claim 5, further comprising a drive belt extending between an output pulley of the second electric motor and the bristle bar.

7. The vacuum cleaner of claim 5, wherein the first and second motors receive electric power from discrete battery packs located in the suction housing and cleaning head respectively.

8. The vacuum cleaner of claim 5, wherein the first and second motors are activated by discrete switches—

one of which is located on the suction housing and the other of which is located on the cleaning head.

9. The vacuum cleaner of claim 5, wherein the first and second motors are activated and controlled by a single switch.

10. The vacuum cleaner of claim 1, wherein the first compartment is located within a suction housing and the second compartment is located in a floor-traversing cleaning head that is pivotally interconnected with an intermediate housing to which the suction housing is detachably connected.

11. The vacuum cleaner of claim 1, further comprising a nozzle extending from the first compartment into the intermediate housing.

12. The vacuum cleaner of claim 2 further comprising a handle detachably connected to the suction housing.
