It is unfortunate that no one produces portable workshop cyclones.
The reason for this is Dyson owns all the patents on making
small cyclones work, and either he has to licence them to someone
to build workshop versions, or he has to do it himself, neither
of which seem to have happened. I suspect the market is too small
to fund even a fraction of the development work which Dyson does
from his domestic sales. There used to be a ruggedised DC04
(looks identical, but is made from a different plastic),
but it cost a fortune.

This has to be one of the best sites for research into cyclone
collection for the workshop:
