I end up with Windtunnels just by desperation at not finding any other vacuums, or I see a good deal on store salvage or Amazon return salvage and snag them. Most of mine are all new models from the past 10 years. I do have the twin chamber Windtunnel that got snapped in half in shipping, and I also have the first model Windtunnel that was later recalled due to the on/off switch melting and catching fire for reasons unknown, Hoover offered a free replacement/repair at the time. Mine has never been tampered with. I also have the recalled T-Series that was recalled for cord overheating inside the rewind housing.
