Hi there. I was about to re-make my original comment that the Turbopower 1000 went on sale in 1992 and not 1994 as someone suggested, but I see that in one of those excellent pictures in this thread that there is a 1993 model pictured. I have a personal memory for the date, because I'd been running my shop for a good few years by then, and my late wife worked in the electrical buying office for Great Universal Stores. The Autumn & Winter catalouges featured three very new cleaners, one being the Hoover Turbopower 2, the other being the Turbopower 1000, and the other being the Dyson DC01, which I have to admit to finding highly hysterical to look at. I really thought it was going to be one of many types of things that one would only ever see in a catalouge and would not be around for long. Well it just goes to show. The Dyson was not avaliable until the spring of 1993 but I do believe orders came in to GUS.
My wife also had a Turbopower 3. She bought it from new in the new year of 1997 as the House of Fraser group were doing them on some sort of end of line deal. That woman was House of Fraser barmy. It was model 2881, which was a very late production model and was the exact same cleaner as the 2880 but in this case the boost setting had to be activated every time the cleaner was switched on, unlike the 2880 where the boost button was locked in place for the duration. This drove my wife insane as she did not ever use or want to use the cleaner in autosense mode. If she had paid full price and chosen the cleaner, it would have seemed stupid not to want the autosense, though I expect a good many people paid for the feature and never used it. In any case, she put up with having to reboost the cleaner each time until I eventually happened upon a scrap cleaner which had the old style switch and fitted that panel to her cleaner. She ended up keeping it for quite a long time.
The strange thing was that in the years which passed, I had a 2880 in for repair which had the 2881 style switch panel. I didn't think to check the date. Whether this machine had recieved a replacement panel at some point, I have no idea.
