I must say I am surprised that a new vacuum cleaner today has a light. My Father worked for Hoover from 1948 to 1978, then he opened his shop selling and repairing all makes of vacuum cleaners. I followed in his footsteps and remember the 70's.
Hoover introduced the “Dirt Searcher” vacuum cleaner in 1974 and on TV it looked great. The ads for it showed it searching out and cleaning dirt you and I never would have found without the light.
My Dad Pat Mackle (sadly deceased) said “What a lot of nonsense, when I hoover, I clean everywhere I can reach, not just the bits of dirt I can see”
Though I remember the Hoover Dirt Searcher Add on TV and I have to say it looked good (but then that is the whole point of adverts)
Often it is said “There is nothing new under God and the Sun” So I can only think that the new vacuum cleaner you have bought is doing exactly what every manufacturer does. Take a good idea, market it, let it rest for a while, then do it again.
Adding a light to a vacuum cleaner is no real help to those of us who clean well, but for those who are lazy cleaners, maybe cleaning where the light shows dirt is a great short cut.
Shame really because there are types of lights these days which actually kill germs (Uv and ozone) which would be a great addition to a vacuum cleaner.
As My Dad used to say in the 70's when he was selling them. “Mrs, now you can clean in the middle of the night with the lights out and really irritate your Husband”
