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.
