I am now using a Hoover GUV with a separator. It works fine for a while. The only stuff that gets by the separator is the fine dust, and that clogs the filter pretty fast.
I see a 12a househole cyclone vacuum on ebay. I am thinking (hoping) that the fine dust would settle out in the cyclone, so I will have a good system forever. Anyone try this?
My experience with cyclones is that the heavier stuff drops down into the pre-cannister, so the only thing that gets to the vac IS the finer dust. You're gonna need more filtering, I'm thinkin.
I have never used one but that was was I feared. The Dyson claims it has no filters of any kind. How do they do that?
Actually, the Dyson (at least some models) does have a final-stage hepa-filter. It'd be interesting to see how it does with drywall dust.
I suspect the current best bet for fine dust would be a shop-vac sized cyclone (either the Oneida or the Clearvue) then a shopvac with a Cleanstream (water-washable, HEPA) filter.
I've had a Cleanstream on my Ridgid shop-vac for a couple years now, and really like it. It clogs up with lots of drywall dust but the exhaust air stays clean.

I'll second that - I have a HEPA (Cleanstream IIRC) on my Ridgid shopvac also, and it filters VERY well. A lot of fine dust builds up directly on the filter, and I usually just shake it out inside a garbage bag when I start noticing a suction reduction. (I made a rhyme...) Once in a while I rinse it under the tap and kind of unfold each pleat to let it really clean up. Re. the Oneida vs. Clearvue mini cyclones, have you taken a close look at either one? Do you think they're much different? Thanks, Andy
The Clearvue uses 2.5" ports in and out. The Oneida has a 1.5" intake port and a 2" output port. If you've already got a shopvac that uses
2.5" hoses (Ridgid, Craftsman, Shop-vac, etc.), then the Clearvue is more convenient as you can use all your accessories.The Oneida looks more "professional", and the DIY version of the Oneida is actually cheaper than the Clearvue.
I have no idea how they compare with respect to separation performance.
