I'm not one for drama either... I have enough of that in my life already--vacuums help me regain my sanity a lot of the time.
I do agree with both of you-- Jeff and David.. It was partly pilot error... but I also think the design could have been improved--or not even used at all.. Hoover has always been good at over-engineering things, too. I mean, the spring. Classic. Just makes sense. And Hoover must have had reports of folks snapping handles. But, I also see what Hoover was doing; as they have always looked for ways to make the TOL model just that: TOL.
They're stil doing it today, look at the little things; 24' cord vs. 31' cord; the Embedded Dirt Finder; a 2-year warranty; 15" cleaning path vs. a 13" cleaning path; a blow-molded hose vs. a stretchy hose.. It would make a lot of people's lives easier if we just had a few models to choose from.
The "diving board" machines that I have, have no signs of handle cracking whatsoever, and operate just swimmingly. Now, if I over-filled the bag, ran it into furniture, and was rough with them, I'm sure it'd be a different story.
I also have a few machines that have the "foreskin" still intact. That was kind-of a silly design, but it worked. If the user over-filled the bag, too, that part could become stretched out. The desintigration of that piece could also be caused by the climate in which the vacuum is/was stored. Dry climate=it will dry out. Damp climate=it won't. Finding them still operational is fun. But again, a simple spring works without a problem...
The headlight lens falling out could probably be attributed to pilot error also on some level--I mean, sure... ram the machine into a sofa hard enough, and it will pop out. I wonder why they didn't fix that problem until well into the 70's..?
Just my two cents.
