Bought this a few years ago to avoid constantly emptying my dust collection bag. My best result, so far, is to have the secondary can with this lid approaching 1/2 full before the D/C bag is stuffed full and suction is gone. I'm heading out to get a dust deputy or similar as this is really not working out. Doesn't even separate the fine/big bits of debris. Both make it through to the main bag for that messy cleanup I was trying to avoid/mitigate.
