1. A vacuum cleaner comprising:

  • (a) a cleaner head adapted for movement over a surface and having a fluid nozzle positionable adjacent the surface;

    (b) a handle for moving the cleaner head over the surface;

    (c) a casing housing a cyclone chamber having a cyclonic flow region in communication with the fluid nozzle;

    (d) means for introducing a fluid flow to the cyclone flow region;

    (e) means for removing the fluid flow from the cyclone chamber;

    (f) particle receiving means disposed beneath the cyclone flow region for receiving particles separated from the fluid flow;

    (g) separation means for essentially isolating the particle receiving means from the cyclone chamber except for transporting means associated with the separation means for connecting the particle receiving means in flow, communication with the cyclonic flow region such that, in operation, particles pass through the transporting means to the particle receiving means.
