The Super Vac Cloud 9 produces huge amounts of pure white smoke with no breathing discomfort. Other units frequently clog, leave slippery residue on surfaces and produce only rapidly dissipating smoke that also burns when inhaled. Super Vac has solved all these problems with the easy to use and transport, mineral oil based Cloud 9 Smoker featuring an automatic clean cycle that runs every time the machine is operated as well as using fluid that is less expensive.
