Here is a tip for the Patriot. You will soon find out why it was in a thrift store cheap. Using the open top Stormy bag it is nearly impossible to change bags without having a bunch of dirt fall back into the vacuum. The lid is angled down towards the front of the body. Dirt piles up on top of the bag under the lid from the cyclone effect. When you open the lid dirt falls out on the floor and no matter what you do dirt always manages to fall into the bag chamber as you change the bag. It is the reason I parked mine. I did try their closed top Hybrid bag ( which requires use of a rubber inlet spout extender to poke through the rubber seal in the bag, available from Schoettler ), but it leaked so much dust that I had to rewash the cloth bag after only one use. Terrible bags ! Switching to a VAC USA synthetic bag doesn't solve the problem as the dirt still piles up on top of the bag and falls into the bag chamber and inner bag during bag changes. Mega frustrating!
I am going to try a synthetic dust bag from Ghibli Vortech intended for use in the Vortech XR3000. You can buy these on eBay. They are nice microfiber dust bags with a round card on top like a Miracle Mate bag so it is sealed to the spout in the lid. If these fit then the problem is solved. I also intend to try them on my Miracle Mate.
