Abstract

Disclosed is a floor-treating machine having a frame with actuating means. A housing is attached to the frame such that it can rotate about a substantially vertical axis. At least three heads are mounted in the housing and each can rotate about a substantially vertical axis. The heads are provided on their bottom surface with treating means and/or coupling means for treating means to be coupled to. A shaft of the motor is concentric with respect to the vertical axis of the frame. The shaft is in driving interaction with the housing and the heads by means of respective transmissions. The transmission for driving the housing includes an auxiliary shaft that runs parallel to and at a distance from the axis of the frame. The auxiliary shaft is connected to the motor shaft via a first auxiliary transmission and to the housing via a second auxiliary transmission.
