    • 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. In one aspect there is provided a walk-behind floor treatment machine comprising: a base portion provided with and supported by at least one rotatable work head for treating the floor, a handle portion for steering or guiding the machine along a working direction of travel and adapted to be pivotable with respect to the base portion, drive means for rotating the work head with respect to the base portion, floor-engaging wheel means for supporting the handle portion, the wheel means having a substantially transverse axis of rotation so as to permit travel in the working direction, the wheel means being coupled to the base portion by a linkage which permits vertical travel of the base portion and associated work head or heads with respect to the wheel means, but which provides transverse constraint to limit or prevent yawing of the base portion with respect to the wheel means, wherein a lower region of the handle portion is pivotably connected to the wheel means via an articulated joint, the arrangement being such that the handle portion may be manipulated to act on the wheel means so as to yaw steer the wheel means about a yaw axis defined by the floor-engaging contact of the wheel means, the yawing of the wheel means causing the base portion to yaw in response to yaw steering. The wheel means may comprise a wheel, roller or ball, preferably a single wheel, roller or ball, disposed at a lower region of the handle portion. The wheel means preferably has a fixed transverse axis of rotation.

    • 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 floor treatment machine comprising a base portion provided with two or more rotatable generally disc-shaped floor- facing work heads which are arranged side-by-side on the floor and each having a generally vertical axis of rotation, the machine being provided with drive means for rotatably driving the work heads in counter-rotation with respect to one another, and wherein the rotational axes of both work heads are tilted transversely from their respective verticals so that the axes are convergent or divergent in opposite transverse directions thereby causing the work heads to adopt dihedral or dihedral configurations when viewed from a front of the machine, which configurations in use provide propulsion of the machine over the floor surface, wherein the respective work head axes are also both tilted backwards away from the vertical so that both work heads are tilted-up at front end regions thereof and depressed at rear end regions thereof with respect to the floor surface.
