Abstract
An extraction machine for cleaning a floor surface, such as carpeting, has a cleaning solution dispenser capable of dispensing a chemical cleaning agent onto the floor surface, and a source of chemical cleaning agent carried onboard the extraction machine and defining an interior space for holding chemical cleaning agent. The container has an opening and a closure for the opening, with the closure having a passage extending therethrough in fluid communication with the interior space of the container. A chemical delivery line provides fluid communication between the passage and the cleaning solution dispenser for delivering chemical cleaning agent from the container to the cleaning solution dispenser. A metering device is disposed generally adjacent the container closure in fluid communication with the passage for metering the flow of chemical cleaning agent from the source of cleaning agent.
