You have to admit the washing machine is one of wonders of the modern world, yet taken for granted. Until they were invented, a wife or servant essentially devoted most of a whole weekday to washing clothes. A washing machine and dryer cuts this to a couple hours a week. Clever people seek to cut this time even further.
Maybe if you're doing a single person's laundry. Our family laundry is a job for more than a couple of hours.
