Two more things I've picked up since re-reading this thread. There is mention of a Co-Op exclusive Turbopower Junior bing made around the year 2000. Can anyone comment on this as I am not sure which one this would be. The only one I know of was deep red in colour and something in my head is saying it had a more powerful motor, maybe the 650w motor. But that was a mainstream cleaner, not an exclusive.
Jmurray, when you speak of the Turbopower 1000 being a spur of the moment cleaner, with the Turbopower 1,2, and 3 being planned, it is immpossible to know what went on inside the minds of those at Hoover, but I would be inclinded to disagree with you in a way. The original Turbopower (which as I said earlier only took the title of Turbopower 1 towards the very end) was probably very much planned. However this cleaner was never ever designed to have on-board tools, and it is my suggestion that when the Turbomaster was designed, the tool caddy and hose caddy was made in such a way that it would fit both the Turbomaster and the existing Turbopower. Had the Turbopower been designed for on-board tools from the start, I cannot think for a moment that Hoover would have intentionally made a cleaner where the hose caddy and hose end at the cleaner entry-point overhung the side of the machine in the way that it did on the Turbopower Total Sytem. That was a terrible design flaw, causing damage to both cleaner and anything in the home which it scraped against.
Also, the whole design of using the height selector to shunt a valve across to use tools was poor. In all it had the hallmarks of an after-thought.
The Turbopower 2 and 1000 were also quite likely to have been well planned out. It is the idea of selling practically identical machines (which they were apart from the wattage, as there were models in both ranges with identical features) which totally confuses me. It would seem that someone at Hoover also saw this for what it was, and therefore the Turbopower 3 was launched instead. There may have been no plans for it way back in 1992, but certainly it meant that the ranged now 'flowed' rather smoothly, and obviously it featured a new full-length stair cleaning hose, which really did seperate the Turbopower 2 from the Turbopower 3, as cleaners with on-board hoses had always been known for their short hose. A stair cleaning hose was a must-have feature for many customers, and one which they'd willingly pay more for. Electrolux and Dyson were doing the same, so it made sense that Hoover had to add a longer hose in order to compete.
I suppose all products are planned, it is where they end up and what bits come & go during their production run that makes the product take on a more random nature.
