In the picture above you can see a nineteenth-century prototype of the current washing machines, in practice a machine Wood who washed the laundry through a crank.
The operating system of this rudimentary machine to revolutionize everyday family life was very simple, but he had the merit of helping not just the women in regard to the task of almost daily laundry.
it worked like this: a kind of wooden basket was placed in a larger box, also made of wood, filled with soapy water and the whole was driven by a crank which made rotate the smallest box in the water.
There followed a little later a further change, the roller wringer.
The washing machines were manual until the advent of’electricity.
