Abstract
A recovery system for use in a floor cleaning machine of the type including a dispensing system and a recovery system. The dispensing system configured for dispensing a liquid cleaning solution onto a floor surface to facilitate the removal of dirt from the floor surface. A recovery system configured for recovering cleaning solution and dirt from the floor surface thereby leaving a cleaned floor surface. The recovery system comprises a recovery tool movable over the floor surface. The recovery tool comprises a body including an interior suction chamber in fluid communication with a source of vacuum. At least one blade is secured to the tool body and depending therefrom for engagement with the floor surface to provide fluid communication between the suction chamber and the floor surface, whereby cleaning solution and dirt are suctioned from the floor surface. The blade is substantially rigid to inhibit deformation of the blade during operation of the floor cleaning machine and is movable relative to the tool body such that the blade remains substantially in engagement with the floor surface while moving relative to the tool body to adapt to contours in the floor surface.
