I get _no_ dust in the vacuum. The cyclone is that efficient. Well,
the tall one is - the older one let some dust through.

I agree, had a problem dust that we needed to keep out of the toxic vac,
made a tub cyclone and 99% gets caught in it, the 1% might be caught by a
taller unit but that won't fit in the location. We've also got a Record 3
motor extractor that could do with a cyclone, but as space is a big
problem we just change the filters regularly, get those wrong and it stops
working as the dust (mainly graphite) shorts the motors out....
