Your Air-Storm, Tri-Star, Patriot, and Miracle Mate vacuums are every one offered in people's homes across the USA. All these machines are essentially premium canister vacuums with a unique technique to keep the cloth container (which has a paper bag inside) from clogging up.
The most important claim to fame that the Miracle Mate, Tri-Star, and Air-Storm has is that the dirt bag in fact never clogs up, and you never lose your power. The only way to lose any power is to fill the container so packed that the dirt and pet hair is backing up into the hose. That is almost impractical to do. The air goes into the paper filter bag at an angle that forces the air stream to continually blast the back of the bag. Keeping it unclogged to permit unspoiled airflow.
Additionally, you'll stumble on several added vacuums that utilize that air flow technique. The Tri-Star, Miracle Mate, Air-Storm, and Patriot vacuums use the similar method of forcing the air over the dirt vs through the dirt. The benefit that the Miracle Mate has, is how the paper liners are sealed at the top, and the lid of the bag compartment has a short nozzle that opens the seal at the top of the paper filter bag, when the lid closes. If you dispose of the packed paper liner to throw it away, the dirt and pet hair is trapped in the container and will not leak out into the room.
Your Tri-Star and Miracle Mate shells are manufactured out of metal, and the Air-Storm is manufactured from a high impact resin material. All the shells are almost shatterproof.
Your main shell of the Miracle Mate is warrantied for a 30 year period and 3 years on everything else. That is a quite exceptional warranty. The Air-Storm warranty is three years, The Tri-Star warranty is 25 years on the shell and five years on everything else. The Patriot has a 35 year shell warranty and 5 years on everything else.
All these vacuums utilize sealed HEPA filtration. None of these machines leak dust.
So the vacuums filter the air as you sweep. All these models can assert accurately that they filter the surrounding air as you use them to vacuum.
All these vacuums have power nozzles to use on carpeting, brushing the dirt and pet hair from the carpet fibers. All use premium attachments for dusting and vacuuming upholstery.
These vacuums all retail for more or less the equivalent price. The Patriot, Tri-Star, Air-Storm vacuums are manufactured in the USA. The Miracle Mate vacuum cleaner is manufactured in both the USA and Canada.
