It was Panasonic who bought the DAM patents when Hoover dropped the cleaner in 1979. Back then there were really only two "clean air" vacuums on the market, the DAM and the Kenmore Duo Power. Hoover dropped the DAM in favor of the open fan design for its uprights, as the open fan design cleaned better.
They also said they'd never make another clean air upright.
They ate their words in 1997 when the Windtunnel was brought out. By then all their major competition(Dirt Devil, Eureka, Regina, Kenmore) had clean air uprights in their lines, and here was Hoover saying their BOL Elite cleaned better. People were breaking Elite fans like crazy, and buying other cleaners.
Hence the Windtunnel.
MrClean: I've done the speed thing with Convertibles, it improves suction, but also makes the cleaner hug the carpet too much, and its very hard on the motor. I once had a Decade 80 that I replaced the powersurge switch with a regular one, using the cleaner in HI all the time. The motor started to deteriorate right away, and eventually threw bars off the commutator.
Today I would never abuse a Convertible in such a way. I leave it on low speed for carpets, the way God intended it to be!
