I'm all for, but you make it sound like it's easy as pie. Proper cyclone modelling requires a few factors to be taken into account doesn't it? Like the suction pressure, size of the air inlet and outlet, and a few other parameters. It's enough mind abusing that people sometimes managed to write over 100 pages <http://monarch.qucosa.de/fileadmin/data/qucosa/documents/5333/data/diss.pdf> about this topic. And here is another dude <http://billpentz.com/woodworking/cyclone/cyclone_plan.cfm> that details the build process of a sawdust dust collector that uses cyclonic separation (the very object of inspiration for the dyson products). However I have never heard of orcy, neither seems google. Is it similar to the technology of those industrial cyclonic separators used to clean gas using a fluid that's injected into the cyclone? Anyways, I have two 1000W vacuum turbines that were pulled out of an industrial vacuum (a numatic I believe). I got them for a dust collection project I have in mind, don't know if a portable dust collector/vacuum can be designed to make use of them. If it does, it would mean more shelf space for me, a fun project to collaborate on, and a proper cleaning equipment for the lab ... However to reduce the noise, maybe as suggested earlier by Armin, a centrifugal fan would make meeting the requirements easier.

few junk parts to build a wet spill attachment <https://www.youtube.com/watch?v=GrgSlbnjy-U> for the vacuum we already have?
when I heard about the issue in more detail now, I thought: why don't we build a much better vacuum cleaner ourselves? Actually I would want a cleaner with wet-capability myself. There is a good design, that employs liquid cleaning / gas washing of the air called "Orcy", that was presented to me.
I envision a design, that combines the idea of the Dyson, a cyclone, for the coarse mud with the idea of the Orcy, a gas washer, for excellent fine filtering, if it's done right. For prototyping of the air-nozzels 3D-printing will work nicely and a sketch is in my head...
Other requirements: *) very quiet *) robust & repairable *) relatively cheap
By designing a good centrifugal fan and strapping standard vacuum cleaner tubes/hoses and floor-nozzles to a newly engineered body, this should be achievable.
