I use an Easy from 1934 -- it's more work than an automatic, you can't just throw your clothes in and read a magazine till it's done. To do a white load, you need to fill the tub (using a hose or a bucket if your machine doesnt have a pump), add soap, run the washer for five minutes or so, wring, drain the tub, refill with rinse water, add bluing and vinegar, rinse for for five minutes or so, wring, drain the tub, and then hang the washing on the line.
If you do a mixed load, you separate the white and the colored, wash the white load first, wring and put it aside. Then wash the colored load in the same water, wring, and drain. Do the same thing with the rinse water .
Using a wringer machine puts you right up close to the job -- and if you empty the tub by draining into a pail, you can forget about needing to join a gym to tone your arms. And it uses a *lot* less electricity and water than any modern automatic.
