Suppose you could wish a washing machine!
"Wouldn't you wish for a machine that would never require you to put your hands in hot, sudsy water to rinse, blue, or dry ?"
--The Columbia Evening Missourian, March 11, 1922
The ad on this page explains pretty much how it works.
You'd still have to hang the laundry on the line, of course. I saw an ad for a 1920s dryer once, but out in Arizona I'm sure they did not sell well.
As a woman who hates cleaning, I've got to say I'm glad it's not 1922.
