Abstract

An upright extractor for delivering cleaning fluid to a cleaning member, removing the cleaning fluid and entrained soil from the cleaning member, and damp wiping dirt and debris off of a surface to be cleaned. A roller assembly for wiping dirt and debris off a cleaning surface is reversible. The roller assembly and a centrifugal pump are driven simultaneously and at independent speeds necessary for preferred operation with a common motor. A vented spray tip assembly delivers cleaning fluid to the cleaning member. An improved accessory tool delivers a variety of metered cleaning chemicals while also extracting the soiled fluid and debris from a surface to be cleaned.
