ABSTRACT:
A combined floor scrubbing/floor burnishing apparatus comprises a machine frame (16) supporting a motor-driven surface-working head arrangement (27), a device (10) for selectively varying the pressure exerted by the head arrangement on the surface, and a unit means (40) for selectively varying the speed at which the head arrangement is driven by the motor so that the higher operational speeds required of the surface-working head arrangement can be readily achieved at the reburied lower application pressures and vice versa.
