re: Went from a 5 micron bag to a 1 micron cannister.

Jeff the regular price on this one was 250.00 with the 15% off, dropped it down to 212.00. The handle is attached to to a steel shaft that runs down the center of the cannister. Attached to the shaft are two rubber tipped paddles that hit the flaps and cleans off the attached dust down into the bag when you rotate the handle. I read a lot of reviews and I have a friend who bought one a couple of months ago and he loves it. Here is a pic of the interior.
