ABSTRACT:
An extraction machine for cleaning a floor surface has a front and a rear and is movable by an operator relative to the floor surface in a forward direction of travel to clean the floor surface. The extraction machine also has a cleaning solution dispenser capable of dispensing a cleaning solution onto the floor surface and a recovery system for extracting a dirty solution from the floor surface. A towline is connected at one end to the extraction machine and is configured for being supported by the operator at an opposite end thereof such that movement of the operator in the forward direction of travel causes tensioning of the towline. The tension in the towline applies a pulling force to the extraction machine to move the extraction machine in the forward direction of travel.
