ABSTRACT:
A brush pressure system for a cleaning or sweeping machine, particularly of the pedestrian type, has elements for biasing the brush or brushes against the surface to be cleaned or swept, at a desired value and preferably at a controllably variable value. Long springs mounted in spring tubes which are compressed by an electrical actuator are the preferred option. With a controllable brush pressure the cleaning or sweeping machine is more adaptable, can be used for both heavy duty cleaning or scrubbing tasks and light sweeping tasks without the need to for resetting the machine in the factory and without wearing out the expensive brushes or damaging the floor surface.
