You guys do realize, don't you, that the Dyson Big Ball HAS a post-motor filter. It's not designed to be washed or cleaned - but there is a filter. Plaster dust will come through the Dyson Cinetc's cyclones, and clog the post motor filter, which is why they say not to suck it up.
As far as the Rainbow, until 1998 there were no filters at all, just water. Plaster dust (and fire place ashes) can't be wet easily by water. However, Rexair made a chemical (similar to Jet Dry for dishwashers) that made the water "wetter" and allowed the machine to pick up these kinds of materials. Dyson has no such thing to allow the Cinetic to be used for lots of fine dust.
