I am a big fan of both Air-Way and Rainbow, and sell them both. I still have trouble figuring out what makes any of the European canisters special, other than a protected profit for their dealers. This includes Miele, Bosch, Sebo, etc. I am constantly approached by these companies to sell their products, but have not done so. They are all very well built machines, but of very conventional technology. I love the Air-Way for the fact that it is built the way it always has been. Incredible, all metal, hand built quality. If a customer needs a vacuum that performs only the traditional functions of a vacuum cleaner, Air-Way is the way to go.
Now the Rainbow is a completely different situation. They have completely overcome the objection of being difficult to set up and use, with the new e2. The e2 is A.H.A.M. certified as an air cleaner, and designed to be used like any other air cleaner, running continuously around the clock 24/7. To accomplish this, a new motor, which has no carbon brushes (to produce emissions or limit motor life) has been developed. On low, air cleaning, speed, the machine is virtually silent. The user lets it run all the time, cleaning the air, which it does with better than HEPA results. When you want to vacuum, you simply connect the hose, and turn the switch on to high speed. When finished, pour the dirty water down the toilet, refill the basin with clean water, and turn the machine back on, on low speed, and let it run. I have talked to customers whose machines have run 24/7 for two and a half years, since this model was introduced. The machine also picks up water, enabling it to scrub the kitchen floor, and clean carpet. The new AquaMate II shampooer is very convenient, and does such a good job that there is no product I carry on which I have received as many compliments on the job it does. And these machines have a history of running for 40 or 50 years without problems. What is also amazing is that in the US, the Rainbow is the second largest selling canister cleaner on the market. Only the combined number of Kenmore and Panasonic (who build the Kenmores for Sears) is greater. And according to surveys conducted by Nordhaus and Associates of Southfield, MI, and The Schoenwald Group, of New York City, the Rainbow has the highest owner satisfaction rating of 98%.
