  • Patent number: 7025835
    Abstract: A floor cleaning machine has one or more barriers immediately behind one or more scrubbing brushes, wherein the barriers capture and control flow of a cleaning solution (and/or other substances) that exits from beneath the scrubbing brush(es) so that such a solution is retained adjacent the scrub brush(es) and recycled underneath the scrub brush(es) for enhancing the floor cleaning effectiveness of the floor cleaning machine. The captured solution is urged back into contact with the scrubbing brush(es) by the same rotating action that urged the solution to be ejected from the scrubbing brush(es). The machine also includes at least one splash guard and a squeegee mounted at the rear of the machine, with each of these latter components serving distinctly different functions from that of the barriers. The machine may also include an exterior top storage area for retaining various items that are useful in cleaning the floor.

  • Patent number: 6131240
    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.
