“Express” or “Quick” wash cycles simply perform the agitation mode of the wash cycle for a shorter period, and may skip a 2nd rinse/drain cycle as well. And this is fine, if your clothes are only lightly soiled/dirty.

Laundry centers generally stack a dryer on top of a washer in one integrated unit. Because of this, a laundry center has the footprint of one appliance but is much taller, but they perform similar to traditional American washers and dryers. On the other hand, washer-dryer combos combine washing and drying in one box.
