Abstract: The present invention relates to the field of floor treatment machines for scrubbing, polishing, sanding or burnishing floors, and in particular machines in which one or more driven rotatable work heads (such as scrubbing brushes) are provided for agitating the floor surface.

Abstract: The present invention concerns the field of floor treatment machines such as scrubbers, finishers or polishers. Floor scrubbers typically have rotating work heads equipped with bristles for working the floor to remove dirt. The invention provides a hand-guided floor treatment machine comprising a handle portion connected to a base portion, which base portion is provided with a rotatable generally disc-shaped floor-facing work head having a substantially vertical axis of rotation, the machine being provided with drive means for rotatably driving the work head, wherein the rotational axis of the work head is slightly tilted away from the vertical in a direction which has a transverse component and a rearward component so that the work head is biased into contact with the floor in a region rearwardly and to one side of the work head, whereby in use rotation of the work head through the biased region provides propulsion predominantly in a forward direction.
