Abstract

A dirt collection region of the vacuum cleaner is removably positionable in air flow communication with an inlet port of an apparatus in which the openable door of the dirt collection region of the vacuum cleaner is positioned interior the apparatus. The apparatus has an air treatment member. When the apparatus is standing on the floor, the apparatus has an upper end which has the inlet port. When the dirt collection region of the vacuum cleaner positioned in flow communication with the inlet port of the apparatus and when the system is in the emptying mode of operation, a motor and fan assembly of the vacuum cleaner moves air from the dirt collection region of the vacuum cleaner as dirt, which has been accumulated in the dirt collection region of the vacuum cleaner, travels to the air treatment member of the apparatus.

Claims (28)

1. A system comprising a vacuum cleaner comprising a dirt collection region and an apparatus for receiving dirt from the dirt collection region of the vacuum cleaner, the dirt collection region has an openable door, the apparatus comprising:

(a) an air flow passage from an inlet port to a clean air outlet, the dirt collection region of the vacuum cleaner is removably positionable in air flow communication with the inlet port wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port, the openable door of the dirt collection region of the vacuum cleaner is positioned interior the apparatus; and,

(b) an air treatment member positioned in the air flow passage downstream from the inlet port, the air treatment member comprising an apparatus dirt collection region,

wherein the apparatus is configured to be free standing on a floor and, when the apparatus is standing on the floor, the apparatus has an upper end which has the inlet port, and

wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port and when the system is in an emptying mode of operation, a motor and fan assembly of the vacuum cleaner only sucks air from the dirt collection region of the vacuum cleaner as dirt, which has been accumulated in the dirt collection region of the vacuum cleaner, travels to the air treatment member of the apparatus.

2. The system of claim 1 wherein at least a portion of the vacuum cleaner is insertable into the apparatus.

3. The system of claim 1 wherein a garbage bag is removably positionable in the apparatus.

4. The system of claim 1 wherein, when the apparatus is standing on the floor, the inlet port faces upwardly.

5. The system of claim 1 wherein the dirt collection region of the vacuum cleaner comprises an end wall and the end wall comprises the openable door of the dirt collection region of the vacuum cleaner.

6. The system of claim 5 wherein the openable door of the dirt collection region of the vacuum cleaner comprises all of the end wall of the dirt collection region of the vacuum cleaner.

7. The system of claim 1 wherein the upper end of the apparatus is cylindrical.

8. The system of claim 7 wherein the upper end of the apparatus comprises an annular housing having the inlet port.

9. The system of claim 7 wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port and when the system is in the emptying mode of operation, an additional motor and fan assembly of the system produces a downward flow of air that conveys dirt out a lower end of the dirt collection region of the vacuum cleaner downward to the air treatment member of the apparatus.

10. The system of claim 7 wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port and when the system is in the emptying mode of operation, an additional motor and fan assembly of the system produces a downward flow of air that conveys dirt out a lower end of the dirt collection region of the vacuum cleaner.

11. The system of claim 1 wherein the inlet port is provided in an upwardly facing surface of the apparatus.

12. The system of claim 11 wherein the inlet port comprises a majority of the upwardly facing surface of the apparatus.

13. A system comprising a vacuum cleaner comprising a dirt collection region and an apparatus for receiving dirt from the dirt collection region of the vacuum cleaner, the dirt collection region has an openable door, the apparatus comprising:

(a) an air flow passage from an inlet port to a clean air outlet, the dirt collection region of the vacuum cleaner is removably positionable in air flow communication with the inlet port wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port, the openable door of the dirt collection region of the vacuum cleaner is positioned interior the apparatus; and,

(b) an air treatment member positioned in the air flow passage downstream from the inlet port, the air treatment member comprising an apparatus dirt collection region,

wherein the apparatus is configured to be free standing on a floor and, when the apparatus is standing on the floor, the apparatus has an upper end which has the inlet port, and

wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port and when the system is in an emptying mode of operation, a motor and fan assembly of the vacuum cleaner sucks air from the dirt collection region of the vacuum cleaner and expels air to ambient as dirt, which has been accumulated in the dirt collection region of the vacuum cleaner, travels to the air treatment member of the apparatus.

14. The system of claim 13 wherein at least a portion of the vacuum cleaner is insertable into the apparatus.

15. The system of claim 13 wherein, when the apparatus is standing on the floor, the inlet port faces upwardly.

16. The system of claim 13 wherein the dirt collection region of the vacuum cleaner comprises an end wall and the end wall comprises the openable door of the dirt collection region of the vacuum cleaner.

17. The system of claim 13 wherein the inlet port is provided in an upwardly facing surface of the apparatus.

18. The system of claim 13 wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port and when the system is in the emptying mode of operation, an additional motor and fan assembly of the system produces a downward flow of air that conveys dirt out a lower end of the dirt collection region of the vacuum cleaner downward to the air treatment member of the apparatus.

19. The system of claim 13 wherein, when the dirt collection region of the vacuum cleaner is positioned in flow communication with the inlet port and when the system is in the emptying mode of operation, an additional motor and fan assembly of the system produces a downward flow of air that conveys dirt out a lower end of the dirt collection region of the vacuum cleaner.

20. The system of claim 13 wherein, in the emptying mode of operation, air after passing through the motor and fan assembly of the vacuum cleaner, exits the system in the absence of passing through a pre-motor filter.
