The invention claimed is: 1. A hopper opening mechanism of a hopper in a suction sweeping machine of the type comprising a cyclone unit having stationary, angled, blades for forming a cyclone effect, the opening mechanism comprising an actuator mechanism for opening the hopper for cleaning of the hopper, wherein the actuator mechanism also rotates a mesh screen for cleaning of an inaccessible surface of the mesh screen, wherein the mesh screen is part of a filter for the cyclone unit. 2. The hopper opening mechanism of claim 1, wherein a base of the cyclone unit is attached to the mesh screen, the opening mechanism thereby also opening the cyclone unit. 3. A hopper for a suction sweeping machine, comprising a cyclone unit having stationary, angled, blades for forming a cyclone effect and an opening mechanism for the cyclone unit and hopper, the opening mechanism comprising an actuator mechanism for opening both the cyclone unit and the hopper for cleaning of the cyclone unit and the hopper, wherein the actuator mechanism, upon actuation, will rotate a base of the cyclone unit to open the cyclone unit. 4. A hopper according to claim 3, wherein the actuator mechanism also rotates a mesh screen for cleaning of an inaccessible surface of the mesh screen, wherein the mesh screen is part of a filter for the cyclone unit. 5. The hopper of claim 4, wherein the actuator mechanism is attached at one end to the inside of the hopper. 6. The hopper of claim 4, wherein the actuator mechanism is attached at one end to a lid or door of the hopper. 7. The hopper of claim 4, wherein the actuator mechanism is attached at one end to the base of the cyclone unit. 8. The hopper of claim 4, wherein the actuator mechanism is attached at one end to a mesh screen, the base of the cyclone unit being attached to the mesh screen. 9. The hopper of claim 4, wherein the actuator mechanism is attached to a lid or door of the hopper via a linkage mechanism. 10. The hopper of claim 4, wherein the actuator mechanism is attached to the base of the cyclone unit via a linkage mechanism. 11. The hopper of claim 4, wherein the actuator mechanism, upon actuation, will open the lid or door of the hopper by rotating it. 12. The hopper of claim 4, wherein there is a single actuator in the actuator mechanism. 13. The hopper of claim 4, wherein the cyclone unit is inside the hopper. 14. The hopper of claim 4, wherein the cyclone unit is one a pair of cyclone units and the actuator mechanism is positioned between the pair of cyclone units. 15. The hopper of claim 4, wherein the hopper comprises a tipper mechanism for tipping the hopper for emptying any contents thereof through a lid or door of the hopper once the lid or door of the hopper has been opened by the actuator mechanism. 16. A suction sweeping machine comprising a cyclone unit having stationary, angled, blades for forming a cyclone effect, a hopper and an opening mechanism comprising an actuator mechanism for opening the hopper for cleaning of the hopper, wherein the actuator mechanism also rotates a mesh screen for cleaning of an inaccessible surface of the mesh screen, wherein the mesh screen is part of a filter for the cyclone unit. 17. The suction sweeping machine of claim 16 the opening mechanism being for opening both the cyclone unit and the hopper. 18. The suction sweeping machine of claim 16, comprising a cyclone unit having stationary, angled, blades for forming a cyclone effect and an opening mechanism for the cyclone unit and hopper, the opening mechanism comprising an actuator mechanism for opening both the cyclone unit and the hopper for cleaning of the cyclone unit and the hopper wherein the actuator mechanism also rotates a mesh screen for cleaning of an inaccessible surface of the mesh screen, wherein the mesh screen is part of a filter for the cyclone unit. 19. The suction sweeping machine of claim 16, further comprising a centrifugal fan to suck up road dirt and to blow if through a hose into the hopper, the blow from the fan causing air flow through the cyclone unit to cause the cyclone effect to separate dirt from the air flow. 20. A method for tipping a hopper of a suction sweeping machine of the type comprising a cyclone unit having stationary, angled, blades for forming a cyclone effect, a hopper and an opening mechanism comprising an actuator mechanism for opening the hopper for cleaning of the hopper, wherein the actuator mechanism also rotates a mesh screen for cleaning of an inaccessible surface of the mesh screen, wherein the mesh screen is part of a filter for the cyclone unit, the method comprising: providing a hopper with a lid or door for tipping any contents of the hopper therefrom, the hopper being positioned towards the rear of the suction sweeping machine, the hopper comprising a tipping mechanism; and actuating the tipping mechanism to tip the hopper about a hinge point positioned substantially towards the top and rear of the suction sweeping machine. 21. The method of claim 20, wherein the cyclone unit is within the hopper as it is tipped. 22. The method of claim 20 wherein the hopper, to tip out its contents, is rotated by about 110°. 23. The method of claim 20, wherein, upon starting to tip the hopper, the hopper is moved rearwardly and upwards, while being rotated, to move it out of the suction sweeping machine such that, in its tipped position, it will hang substantially upside down, above and clear of the suction sweeping machine. 24. The hopper of claim 4, wherein a base of the cyclone unit is attached to the mesh screen, the opening mechanism thereby also opening the cyclone unit. 25. The suction sweeping machine of claim 16, wherein a base of the cyclone unit is attached to the mesh screen, the opening mechanism thereby also opening the cyclone unit. 26. The method of claim 23, wherein, upon starting to tip the hopper, the hopper is moved rearwardly and upwards, while being rotated, to move it out of the suction sweeping machine such that, in its tipped position, it will hang substantially upside down, above and clear of the suction sweeping machine. 27. The method of claim 21 wherein the hopper, to tip out its contents, is rotated by about 110°.
