I have found that in order to reduce laundry times to something like this, you have to very deliberately make very specific tradeoffs in the types of clothes you wear and purchase. It is perfectly possible to have a wardrobe that is very low-maintenance (such as by opting for synthetics or synthetic blends for all your clothing), but more likely you have some special cases such as wool, linen, and cotton (which may require air drying and/or ironing or steaming), clothing with small stains that require spot cleaning with stain remover, delicates that need to be hand-washed, whites that need to go in their own load with bleach, or other specific cases.
