Is a 10kg capacity washer-dryer too big?
Our current machine has 5kg maximum for cottons cycle and 2.5kg max for easy-care cycle. A little bigger might be useful for bedding and towels, but with clothes we rarely have enough laundry of one sort (darks/whites/etc) to need to do two consecutive loads of the same sort. Plus you need the hanging space.
Is it wasteful to do half-loads? The machines we like all have very high capacities.
