No vacuum cleaner is perfect. Almost every vacuum cleaner has design flaws that create problems. Maybe the biggest problem is that, as the filter bag fills with dirt, there is less airflow and suction. This problem is even shown in bagless vacuums because the filters clog up as the container fills with dirt, dust, and pet hair.
The worst feature that most vacuum cleaners have that they have bags that eventually clog up and restrict air flow. All bags and filters are porous. All bags, cloth or paper, have tiny air holes that allow the air to flow through them. When there is a dirt particle larger than the air hole, the particle clogs the hoe and restricts the free flowing of air. Eventually the entire surface of the bag or filter is coated with this dust. The airflow is slowed dramatically, and that is why your vacuum cleaner loses suction as the bag or filter clogs up.
That restricted air flow is what causes motors to overheat. The Air-Storm vacuum cleaner has an airflow system that constantly keeps the bag surface clean, allowing for constant airflow and no loss of suction. As the air is pulled into the bag chamber, the angle of the airflow actually blasts the back of the bag clean, allowing unrestricted air to reach the motor and flow out the exhaust. The Air-Storm vacuum cleaner casing is made out of a near indestructible resin material that will never warp when heated.
The metal motor in the Air-Storm is a pleasant surprise. Metal is more durable than plastic, and is a conductor of heat. As the heat is generated in the motor, it is dissipated away from the inside of the motor. This keeps the bearings from drying out. Metal motors are far more durable than plastic motors. Most vacuums made, and all that you buy in discount stores have plastic motors.
Remember that Hoover vacuum your grandmother had for 50 years? It lasted because it had a metal motor and metal parts. Most vacuum cleaners are no longer made as well.
The Air-Storm cleaning system also has two HEPA filters that prevent any dust from escaping the exhaust. One of the HEPA filters is optional, and isn't included in the standard package.
The Air-Storm tools have air holes drilled in the, called “venturi air vents” that allow for constant airflow at the tools. This is especially useful if your upholstery is coated with Scotchguard. If your tools shut of the airflow, you won't be able to pick up any dirt at the tool. Other vacuum cleaners also have similar air vents at the tools; Riccar, Tri-Star, and Carpet Pro also use some form of air vets at the tools.
The Air-Storm vacuum cleaner is American made in California, and it's the most well designed vacuum cleaner we have seen. My only complaint is that the Carpet tool, or power nozzle (as it is called) is from a manufacturer that has parts unavailable to most retailers. At $1,895 retail, it's not cheap, but. The Air-Storm gets our recommendation.
I have seen the Air-Storm sold for less online, but a local dealer would be able to provide service far more easily than an internet seller. You always want to buy from an authorized dealer to guarantee warranty service will be provided.
