Abstract: The invention relates to a surface treating machine which comprises a frame (1) and an undercarriage (2, 3) to enable the machine to move over a surface (S). A head (5) is supported by the frame and includes a drive motor (13) and a tool (6) for directly contacting, scrubbing or treating said surface (S). The tool is rotatably drivable by means of the motor. Cardanic drive and coupling means (16) is connected to the tool (6) in a rotationally fixed manner on one end and connected to the drive motor (13) on the other end. Support and spring means (8, 9, 17) for the tool (6), are forcing the tool (6) against the surface (S) with an controlled uneven pressure distribution around the circumference of the tool (6).

Abstract: An apparatus for cleaning a surface is described. The apparatus has a frame and a cleaning member with a brush that rotates on the frame to clean a floor. The apparatus also has main support wheels drive unit, and an auxiliary drive unit with an auxiliary wheel to improve the mobility of the apparatus.

Abstract: A floor cleaning machine constructed as a carriage equipped with a pole and having at least one motor-driven cleaning implement or tool rotating about a vertical axis and for wet cleaning the floor or the like. From a fresh water supply per unit of time there flows-out a regulatable quantity of fresh water to which there is added a cleaning agent, this mixture flowing-out at the region of the cleaning implement or tool. The machine works the floor or the like with the fresh water-cleaning agent mixture by means of the cleaning implement and the thus resulting soiled water is sucked-up from the floor and collected in a separate soiled water container. The fresh water container which supplies the fresh water is formed by part of the machine housing body, whereas the soiled water container is constituted by a separate, portable container which when assuming its working position is enclosed in the machine housing.
