I did an archive search for this and found only one thread reference and no comments on its performance. At the risk of being redundant, does the Cyclone vacuum tube and hose attachment in fact equalize the pressure between the cyclone and dust bin units sufficient to keep the bag from being sucked up into the cyclone? Has anyone modified their existing cyclones to try this out? Parenthetically, I don't see other manufacturers jumping on board with this feature which makes me wonder about whether it works or not.
