The TP 2, 3, and 1000 are not bad cleaners at all. If you compare them to their competition, the quality was far superior to the Electrolux contour cleaners, and on a par with the Panasonic. The downside, as mentioned already, was the weight. However the build quality exceeded that of the original Turbopower immensely. Let me put it to you like this, you would go a long way to find a TP 2, 3, or 1000 with a broken or worn chassis, or main body unit. The whole design of the original TP was flimsy to say the least, although I strongly suspect a lot of it was designed that way so as to limit the life of the cleaner.
One thing which I did not like about the TP 2 and 1000 was the narrow bore hose, which would clog up a lot. Great for people like me who were paid to unblock them, but bad news for the user. Hoover did change this to a wider hose, I have said so many times and am sorry to repeat myself (well I don't mind if you don't), this in the fullness of time was changed again when Hoover reverted to the original narrow bore hose towards the end of production of the TP2. Also the back wheels of all these cleaners were very thin, the whole wheel was no bigger or thicker than a crunchy style biscuit and combined with the weight of the cleaner would sink into the carpet pile, making turning the cleaner more difficult than it might otherwise have been.
To some extent comparing the TP 2,3, and 100 to the original TP is like comparing apples to oranges, as the two ranges had only the names in common. Though I am not saying I personally lust after such features, it always surprised me greatly that none of the TP 2, 3, and 1000 cleaners ever had a head lamp or automatic flexwinder. This effectively made the cleaners a 'lesser' range when compared to both the original TP line up and the Panasonic cleaners which competed with the Hoover.
