Abstract (en)
[origin: EP1262138A1] The invention relates to a surface treating machine, comprising: a frame (1) and a chassis (2, 3) to enable the machine to move over a surface (S) such as a floor. A head (5) is supported by the frame and comprises means (6) for directly contacting, scrubbing or maintaining said surface. The head (5) is freely movable up and down with respect to the chassis (2, 3) and is loaded downwardly by a pressure to adapt to the level of the surface. At least a part of the pressure on the head (5) is derived from the weight of the machine itself. Preferably, the head (5) is connected to a first lever arm (8) of a two armed lever (7) A second arm (9) of the lever (7) is connected to the chassis (2, 3), whereas a pivoting point (10) of the lever (7) is fixed to the frame (1) of the machine. In this way, the pressure on the head is not only provided by the weight of the machine, but the head is also easily adapting to ramps and descents in the surfaces, while the pressure on the head is maintained.
