Not in my experience, indeed a Dyson is the only thing I've
found that actually copes with these. I can normally get 5
or more large canisters full of plaster/cement dust before
swapping a filter. Each canister holds many times the
capacity of a vacuum cleaner bag in any case.

I agree in general, but you need to be more specific about *which*
Dyson. I've got an old DC03 upright (the 'lightweight' one) and
recently had to replace the entire cyclone/canister because the old
one had become internally clogged with DIY detritus. I couldn't find
a way to dismantle that part.

I use a DC04 for DIY. It can swallow the volume/rate of plaster
dust which my plaster chaser (double blade angle grinder) chucks
out, which a Henry couldn't get close to. Henry's initial suck
isn't strong enough to catch all the dust at the plaster chaser
in the first place, and after about 10 seconds, it had virtually
no suck left as the bag was clogged. Tried it bagless and it
just chucked all the muck out the exhaust. Useless.

I recently used a friend's DC07 for plaster dust and sanding dust
(sanding a maple floor with an industrial sander). I noticed
the DC07 (which is next generation fron the DC04) hardly even
got it's washable filter dirty after several emptyings of the
canister, so it would seem that does an even better filtering
job in the cyclone. I also have a DC07, but that's reserved for
housework, whereas the DC04 is used exclusively for DIY.

Nevertheless, Dysons are excellent on the whole and people who
criticise them must either have been unlucky or have an axe to grind.
I was also impressed that I was easily able to buy a replacement part
for such an old machine.
