Hi Ellen
I have the same setup as you, and I give you a +1 on the use of compressed air. I use about
50 psi and a pointed air nozzle. I’ve found that our setup gives a good indication that the can is full
as the suction becomes noticably less.
I think that Wynn recommends the use of compressed air. It is WAY less messy and the dust is
captured in the bag.

I also agree with Mike that some dust in the filter is a good thing.
I hope this is of help. Cheers!!!!
