Or perhaps we should push technology a lot further and do a lot more with the same or less time.
It took a lot more effort to wash clothing in the distant past. Your father wasn't net saving time versus today, as it takes radically less time to do laundry now. You can do a full load of laundry with five minutes of effort now.
Women particularly were laundry slaves in the distant past, it took up an immense amount of their time and effort. It was unpleasant, labor intensive, and very time consuming.
The old processes were horrible:

Just a hundred years ago, clothing was far more expensive in relation to incomes. Mass manufacturing has brought the cost of clothing down dramatically. People used to wear the same clothing over and over again because it took a long time to do laundry and they couldn't afford 10 or 20 sets of clothes.
It takes me about 30 minutes to do my laundry for the week. That's wearing a full different set of clothes each day.
Do a load of towels every 2-4 weeks? 10 minutes of effort.
And just as to the point, the actual physical labor part of it is almost non-existent. Whereas in the past that was not the case. Women used to physically suffer doing laundry before our modern appliances began to relieve that.
Then you get to the quality of life factor. People overwhelmingly want to wear more than one shirt per week. Not just because it's kind of gross once body oils and countless smells cover your clothing over a week, but it's also about fashion or style (which for many people does matter). Ever go to a restaurant, or maybe just a neighbor's house who smokes, and then have your clothing smell like the place afterward? Wearing that around for a week is gross.
