ABSTRACT:
A scrubbing machine is provided in which cleaning solution, usually mostly water, is cleaned and recirculated. The machine includes a frame supported on wheels with at least one scrubbing brush supported by the frame. A squeegee and vacuum hose are located behind the scrubbing brush for removing water from the surface which was supplied to the surface near the scrubbing brush. A recovery tank and a supply tank are supported on the frame with the vacuum hose communicating with the recovery tank. An exhaust blower also communicates with the recovery tank and draws air and water through the exhaust hose and into the recovery tank, exhausting air therefrom. The recovery tank has baffles which form a tortuous path to separate the air and dirty water as they travel through the recovery tank in the path from one end to the other. The recovery tank is separated into two chambers with most water and dirt received in the first chamber in which the dirt settles to the bottom, and cleaner water flows over an upper edge of a separating wall into the second chamber. The water in the second chamber can then be pumped to a dirt separator located in the first chamber and from there back to the supply tank from which water and a detergent, if used, are supplied to the vicinity of the scrubbing brush.
