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,

wherein cleaning solutions reservoirs are selectively removable from the housing, and 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.

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

3. 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.

4. 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.

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

6. The spot extraction cleaning device of claim 5, 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.

7. The spot extraction cleaning device of claim 1, wherein the cleaning solution reservoirs are color coded.

8. 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.

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

10. The spot extraction cleaning device of claim 9, wherein the battery is disconnected from the device to be recharged.

11. The spot extraction cleaning device of claim 10, wherein the cleaning device is coupled to a power source to recharge the battery.

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