Thanks guys.
Yeah I know, KISS and all that, but there might have been a piece of information I am ignorant of, that's why I thought I ask.
Steve, I think that idea would work in a large communal darkroom that sees a lot of people, but in a small place like mine where I am the only user, I think I would better go with a small hand held dust sucker.
I was just wondering if there are any things to look for in a good dust fighter, that's why I asked if there is something like an anti-static one.
I would never think of keeping the body of the vacuum cleaner outside. Would it create dust? Doesn't it suck the whole dirt inside? What's the rationale behind that suggestion?
