It seems that replacing the bag on the MIDI is not always sufficient to restore the dust collection to the tool in use. I find it helpful to unclog the hose for maximum dust collection. Who knew???? [big grin] [doh]
Same advice works with the Mini, CT-22 and CT-36. Been there on all of them. With the old 22 bags, you could plan on a blowout before you got the bag out of the CT.
