Abstract: An improved non-portable cleaning system for performing water-based extraction and related cleaning operations is provided. A system in accordance with the invention is particularly useful for cleaning the carpeting and upholstery of vehicle interiors and can be operated with relative ease by ordinary consumers. In certain implementations, the system can be coin operated. Defoamer chemical can be automatically dispersed into a recovery tank of the system, thereby reducing foaming in the recovery tank. The recovery tank can be automatically rinsed and drained after cleaning operations are completed without requiring additional interaction by the consumer. A vending machine can be optionally provided with the system, allowing consumers to purchase cleaning supplies incident to performing cleaning operations with the system.
