Hoover UK Brochure April 1992.

I wonder why they introduced it with the bag door piston indicator, but then in a very short time blanked this off in favour of a light and sensor which would have cost them more in production costs than the piston indicator?
If I remember rightly, some of the early models had problems with bag doors cracking - could these have been the ones with the piston indicators?

I don't think the piston indicator made any difference to the likeliness for the door to split.

As for why they did it, only Hoover will know.

Based on my conjecture, I'd say Hoover put the piston indicator on the bag door initially as that was the "done thing" at the time with the Electrolux Contour and others, but when they did all the advertising with the U2462 and U2464 Autosense w/ light indicator side by side realised the U2462 looked too basic in comparison.

So they decided to fit an LED light indicator to replace the piston indicator on the bag door and put an emblem where it was so it didn't look plain.

I do believe there were also models manufactured for a short period of time which featured the new bag door but no light indicator and thus no indicator at all.

There aren't many around (if I'm right in saying they ever existed) these days, the reason probably being that people didn't know when to change the bag due to having no indicator to say so (of course the general consumer wouldn't think to physically check or bother to pay attention to suction levels or motor pitch in most cases) and as a result motors burnt out quickly.

Thinking about it, if the bag doors with piston indicators did split more often than ones with the LED lights, then the reason could be that people paid attention to an illuminated light than they did to a piston which could be overlooked and thus changed the bag or cleared a blockage more swiftly.

"...people paid MORE attention to an illuminated light than they did to a piston which could be overlooked" that should read. That's 4 hours sleep and not enough coffee for you.

Bear in mind though that at that point Hoover were also used to LED indicators on their cylinder vacs and then replaced with piston valves - they could well have changed to the LED fixture due to previous bag doors from splitting on other models - and if it had become known as a design fault (handily only promoted by those who bought Which consumer magazine,) Hoover probably changed up to LED lights.

However I do remember my Yellow 900 Special Edition had neither. The LED light position was blanked off and there was no piston valve fitted either.

Does anyone know why they never replaced the turbomaster, My mother had one and it was a far better vacuum than the turbopower 2 which she traded the turbopower in for and then took it back and got the turbomaster repaired.

Well I think it all had to do with the fact that the Turbomaster was a Hoover U.S design. After Hoover U.S parted with Hoover U.K, all other European sales were replaced by European designed vacuums.
