BTW, the only reason why consumer vacuum cleaners are so loud is because consumers associate loudness with suction power.
"Backpack" style commercial vacuum cleaners have more suction, and are barely audible in comparison.

There does not have to be an increadibly loud functional industrial vacuum cleaner, for figuratively everyone to get your analogy, because the Herculean reality of vacuum cleaners is that you cannot clean an augean stable of lego on the floor, without a lot of noise. If you get my analogy.
The point is, when it comes to consumer behavior, I don't think anyone has a clue what to expect. It would not surprise one bit if vacuum companies make louder vacuums because the consumer thinks it works better.
