摘要：
A surface cleaning apparatus (10) comprises a base assembly (12), an upright handle assembly (14) pivotally mounted to the base assembly (12), a fluid distribution system including a supply of cleaning fluid, and a fluid recovery system for drawing dirty cleaning fluid from the surface to be cleaned. The base assembly (12) comprises a fluid supply tank (22) mounted on a base platform (20), and a recovery tank (24) and lid (70) mounted on the supply tank (22). The nozzle (146) assembly is split into three separable sections, and the upper handle (300) is foldable to a storage position. The base assembly (12) further comprises a pivotal brush carriage (210) assembly. A method for renting extraction cleaning machines (10) utilizes a vending machine (600) that dispenses cleaning formulations packaged in single use packages (602).
