Abstract
The invention relates to a hand-held extraction cleaner including a cleaning fluid supply system for supplying a cleaning fluid to a surface, a dirt recovery system including a source of suction fluidly connected to the surface through a cleaning fluid recovery tank assembly, and a rotary agitation brush for agitating the surface to be cleaned. The brush is driven by air-powered turbine assembly fluidly connected between ambient air and the suction source.
