I've been using a Chinese manually operated washing machine, something like a giant salad spinner, at our village house. It can't handle large loads, the biggest thing I've done in it is one double bed sheet. Very heavy work clothes might be too much for it. For regular garments, it works surprisingly well. The central handle position turns the drum slowly to move water through the clothes, I let them soak for an hour or so, turning the handle every time I go past. Then after they're rinsed and the water drained off via a plug in the bottom, a different handle position on the outer edge of the lid is geared to make the drum spin fast. It does need to be on the floor for than and held down with my feet as it wants to jump around, and it's an arm workout for me, especially with a full load or heavier items like jeans ot towels. But a few minutes spinning will get clothes so they no longer drip.
I don't know how long it's going to last, as it's all plastic, even the gears, but so far it's done thirty or forty loads of laundry with no issues. It's far easier than washing in buckets and hand wringing the laundry. It also means if it's raining I can now hang things in the house to dry without causing a drippy mess (though I intend to set up an undercover drying area for winter and wet days).
I do the laundry in the bathroom, saving the drained water in buckets. Used wash water goes on the garden, rinse water and spun out water goes back to become the next load's wash water. Once the summer kitchen is built I'll probably do the laundry out there. Cold water in fine in summer but in colder weather a little warm to take the edge off makes it a much more pleasant task.
