Wringer Washing Machines?
My mom had one. She did not have to wheel it into our kitchen like the photo below because we actually had a "service porch" inside the house, between the kitchen and the bathroom and the "service porch" had a big sink in it. Funny we did not call it the "laundry room".
Mom would put the "pieces of wood" into a laundry basket and carry them outside to the clothesline in the back yard and hang everything on the line to dry in the sun all day.
This is what our clothesline looked like.
