Under communism, how do we clean our clothes?

• It's not really efficient for every housing unit to have its own washing machine let alone dryer
  • some people can dry clothes on lines but some can't
• Washing clothes by hand sucks
• Laundromats suck
• Industrialized clothes washing? I have no direct experience with this

And it needs so much water.

To my mind laundry is one of the most intractable issues.
