Abstract
A cleaning machine is provided with a recovery tank for containing recovered liquid from a floor or other surface that is being cleaned. The recovery tank has a chamber that houses the recovered liquid and within the chamber are a recovery inlet and a vacuum conduit. The recovery inlet carries the recovered fluid for discharge into the chamber and the vacuum conduit is used in creating a desired vacuum to cause the recovered liquid to be drawn into the chamber. The recovery tank is disposed on a cleaning tank for containing a liquid cleaning solution that is applied to the surface for cleaning purposes. The recovery tank covers an access opening in the cleaning tank for receipt of the liquid cleaning solution. A vacuum motor produces the vacuum and is located next to the cleaning tank below the recovery tank. Sealing members insure a proper seal at the junctions for the recovered liquid and the vacuum when the removable tank is joined to the cleaning tank.
