I do know you can buy a quite functional vacuum cleaner for about $100, which is considerably less than you would have had to pay for an equivalent in 1952.
BTW, I haven’t bought a vacuum in many years. I just pick up discarded ones at the curb and check them over. About half the time the only thing wrong is a clog (usually as from sucking up things like pennies or hair pins), a jammed brush or a belt needing replacement. If people can’t operate a piece of equipment, quality isn’t going to do them much good.
I have an old Rainbow a friend was going to toss out. All it needed was a new cord. It's a great vacuum cleaner, but no way would I pay for a new one. I think they ask around $2,000 for them these days.
