Searching this group for the old "soot in loft" problem has turned up
a recommendation for the Earlex Combivac (seems to be about 39 quid at
Argos).

I've scooped up most of the soot by hand (slowly to stop it spreading
too much) and I would like to get rid of as much as possible of the
remainder.

Does anyone have first hand experience of this sort of job? Does much
soot get blown about by vacuuming? I assume that soot is not
considered an "explosive dust" (Earlex say not to use the Combivac
with coal dust).
