ABSTRACT:
A cleaning machine is disclosed having an adjustment apparatus that allows a selected cleaning depth to be maintained, even where the cleaning apparatus has been raised to facilitate transport of the cleaning machine from one area to be cleaned to another. The adjustment apparatus therefore eliminates the need to reset the cleaning depth where the carpet being cleaned is of the same depth as the last area that was cleaned. The disclosed cleaning machine also features a vacuum housing having an integral seal, which provides for a more reliable seal, and simplifies assembly of the housing.
