I don't own a cyclone type vac....
Over here there's a company Oneida, that specializes in cyclones. That have a separate, small unit designed to be used with a stand alone shop vac, called a Dust Deputy. Some folks make their own cyclones with good results, a thread here titled "who needs a Dust Deputy" by Kenbo here for example.
eE use cartridge filters here rather than bags because the surface area is so much greater because of the folds. This allows better air flow .... more air out is just as important as more air in. They do get clogged and it's best to remove them slowly and drop them into a sealed bag to be cleaned outdoors. I must have a total of 6 shop vac scattered about my 2 shops, mostly in the upstairs woodshop. I keep them attached to the radial arm saw, and several bandsaw, and the stationary bench top sanders. They are noisy but work well.
Fein makes a super effective shop vac, they call it a dust extractor I believe. My shop vacs are Rigid brand and are more quiet than most others. Do a search for "Quiet Shop Vac" and see what comes up. I don't think your household vacs will have enough air flow to be effective, but I could be wrong. I also think the cyclone will fill rapidly under severe sanding usage, but I donno? Your computer electronics should be enclosed in a fan cooled and filtered box, as heat and dust are "anathema" to computers.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
