A floor working machine for the treatment of the surface of floors and more especially a floor sanding machine comprises a work plate which rotates during operation. The work plate is connected in a manner transmitting rotation with a holding part arranged above it coaxially, such holding part bearing against the work plate with at least a part of the weight of the machine and being driven by the machine's motor. The holding part is supported adjacent to the center of rotation on the work plate. In this respect work plate is able to be pivoted with a freedom of movement similar to that provided by a ball joint to allow for possible unevenness of the floor. Work plate is arranged furthermore outside the support point opposite to the holding part at a distance allowing the pivotal motion of the work plate and is attached at several attachment points to the holding part, in each case with the necessary degree of axial play.
