Anyway, Turbopowers.
Whilst I've always felt that the Turbopowers were excellent carpet cleaners (and even more so with the Turbomaster), compared with what Hoover made previously and with what was on the market at the time, it wasn't half over priced and very flimsy. Pretty much everyone was offering something more sturdy at the time. You'll hear many models being refered to as "glass" models because the plastics were so britle, they were forever splitting, cracking and shattering. Most notoriously, the TOL 2nd generation U2336.
I always found that the Softbag TP's cleaned better, due to the outer cloth bag giving a larger surface area for the exhaust air, so it kept the airflow more constant in comparison with the hardbag models.
Everyone seemed to be copying eachother in the 1980's - the Turbopower was essentially a rip off of the Moulinex Major and the Goblin Commander was a rip off of the Turbopower (although less so, since it was designed by the same person). It's amusing looking at the catalogues and brochures of the time, watching them all try to out-do eachother.
However, despite being flimsy and overpriced, they sold and sold and sold and sold in their millions. The rarer models tend to be between 88 and 91 when Hoover sales were in decline, but after the Free Flights fiasco, they were common as muck. People were buying the cheapest Turbopower's that they could just to get a free flight ticket, so they were absolutely everywhere once again.
I was never a fan of the Turbopower 2, 3 and 1000's. I loathe the autosense feature with a passion and the cleaners were very top heavy to use. Even though they were far sturdier than the TP1, they seemed to have more issues with narrow hoses and air channels blocking and the bag doors splitting. They didn't groom as well either - the activator was much better when attached to the slower 400w motors of the TP1. It span too fast to actually groom on the TP2/3/1000 and instead just skimmed over the carpet fibres.
