Abstract
The invention relates to a surface treating machine which comprises a frame () and an undercarriage () to enable the machine to move over a surface (S). A head () is supported by the frame and includes a drive motor () and a tool () for directly contacting, scrubbing or treating said surface (S). The tool is rotatably drivable by means of the motor. Cardanic drive and coupling means () is connected to the tool () in a rotationally fixed manner on one end and connected to the drive motor () on the other end. Support and spring means () for the tool (), are forcing the tool () against the surface (S) with an controlled uneven pressure distribution around the circumference of the tool (). The spring-like means () is distributed around an axis of rotation () of the support means (), and is loaded such that the spring-like means () substantially remain biased during their rotation around the axis of rotation (), in order to created a controlled uneven pressure distribution around the axis of rotation of the tool.
