Abstract

An extraction cleaning device housing multiple cleaning solutions that can dispensed by manipulation of a control coupled to the extraction device. Multiple cleaning solution supply reservoirs are coupled to the cleaning device and in fluid communication with a dispensing head. Through the use of the control, an operator can select a specific cleaning solution for a specific application. Manipulation of the control allows for nearly instantaneous conversion between cleaning solutions for different applications. Some embodiments of the cleaning device have a housing with an end that engages the ground during cleaning operations. The housing at least partially contains several cleaning solution supply reservoirs, a rinse fluid reservoir, and an extracted fluid reservoir. A vacuum source can also be housed within the housing.

Claims

1. A spot extraction cleaning device comprising:

a housing,

a head coupled to the housing and adapted for engagement with a surface containing a spot;

a plurality of cleaning solution reservoirs coupled to the housing and in fluid communication with the head, wherein each cleaning solution reservoir contains a different cleaning solution; and

a control coupled to the housing to allow an operator of the cleaning device to selectively control which cleaning solution is dispensed.

2. The spot extraction cleaning device of claim 1, further comprising an agitation brush positioned adjacent the head and adapted to contact the surface during cleaning operations.

3. The spot extraction cleaning device of claim 1, further comprising a rinse fluid reservoir coupled to the housing and in fluid communication with the head.

4. The spot extraction cleaning device of claim 3, further comprising an extracted fluid reservoir coupled to the housing and in fluid communication with the head.

5. The spot extraction cleaning device of claim 4, wherein the cleaning device is automatically controlled, such that when the operator selects a cleaning solution to be dispensed, the cleaning device automatically dispenses the cleaning solution, automatically dispenses the rinse fluid, and automatically extracts the cleaning solution and rinse fluid.

6. The spot extraction cleaning device of claim 1, the control comprises a rotatable dial having a position corresponding to each of the plurality of cleaning solutions.

7. The spot extraction cleaning device of claim 1, the control comprises a plurality of push buttons corresponding the plurality of cleaning solutions.

8. The spot extraction cleaning device of claim 1, wherein cleaning solutions reservoirs are selectively removable from the housing.

9. The spot extraction cleaning device of claim 8, wherein the cleaning device and cleaning solution reservoirs include a lockout device to prevent cleaning solution reservoirs from being improperly placed in the cleaning device.

10. The spot extraction cleaning device of claim 9, wherein the cleaning solution reservoirs are color coded.

11. The spot extraction cleaning device of claim 1, wherein the cleaning solution reservoirs are clear to allow the contents of each reservoir to be viewed.

12. The spot extraction cleaning device of claim 1, wherein the cleaning device is powered via a battery.

13. The spot extraction cleaning device of claim 12, wherein the battery is disconnected from the device to be recharged.

14. The spot extraction cleaning device of claim 13, wherein the cleaning device is coupled to a power source to recharge the battery.

15. A method of removing a spot from a surface, the method comprising:

providing a spot removal device having a plurality of cleaning solution reservoirs, a rinse solution reservoir, an extracted solution reservoir, and a control allowing an operator to select among the plurality of cleaning solutions;

placing the spot removal device adjacent an area with a spot;

selecting among the plurality of cleaning solutions via manipulation of the control;

dispensing the selected cleaning solution onto the area with the spot;

agitating at least a portion of the area with the spot;

applying the rinse solution onto the area with the spot; and

extracting the cleaning solution and rinse solution from the area with the spot.

16. The method of claim 15, further comprising:

selecting a second cleaning solution for treating the area with the spot via manipulation of the control;

dispensing the selected second cleaning solution onto the area with the spot;

agitating at least a portion of the area with the spot;

applying the rinse solution onto the area with the spot; and

extracting the second cleaning solution and rinse solution from the area with the spot.

17. The method of claim 16, further comprising:

selecting a third cleaning solution for treating the area with the spot via manipulation of the control;

dispensing the selected third cleaning solution onto the area with the spot;

agitating at least a portion of the area with the spot;

applying the rinse solution onto the area with the spot; and

extracting the third cleaning solution and rinse solution from the area with the spot.

18. The method of claim 15, wherein the steps of agitating at least a portion of the area with the spot, applying the rinse solution, and extracting the cleaning solution and rinse solution are performed automatically, without operator interaction.

19. The method of claim 15, wherein the step of selecting a cleaning solution further comprises rotating a dial on the cleaning device.

20. The method of claim 15, wherein the step of selecting a cleaning solution further comprises pushing a button on the cleaning device.

21. A spot extraction cleaning device comprising:

a housing,

a head coupled to the housing and adapted for engagement with a surface containing a spot;

a plurality of cleaning solution reservoirs coupled to the housing and in fluid communication with the head, wherein each cleaning solution reservoir contains a different cleaning solution;

a control coupled to the housing to allow an operator of the cleaning device to selectively control which cleaning solution is dispensed;

an agitation device coupled to the head and adapted to agitate the surface during cleaning operations;

a rinse fluid reservoir coupled to the housing and in fluid communication with the head;

an extracted fluid reservoir coupled to the housing and in fluid communication with the head; and

a vacuum source coupled to the housing and in fluid communication with the head and the extracted fluid reservoir;

wherein the cleaning device is automatically controlled, such that when the operator selects a cleaning solution to be dispensed via the control, the cleaning device automatically dispenses the cleaning solution, automatically activates the agitation device, automatically dispenses the rinse fluid, and automatically extracts the cleaning solution and rinse fluid, without operator interaction.
