<p>A floor treating machine has a frame (5) and a housing (6) connected rotatably to the frame (5) according to a main rotation axis. At least three heads (15) are suspended rotatably with respect to the housing (6) according to respective rotating axes, which are generally parallel to the main rotation axis, as well as a number of drive motors (12,29) which is at least equal to the number of heads (15). Each head (15) is connected to its own respective drive motor (12).
To provide a high quality finishing operation, an orbital drive is provided between the frame (5) and the housing (6) for making the housing (6) rotate with respect to the frame.
