A Miele washer dryer combination is useful when you want a Miele washing machine and dryer in one. If you don't have enough space for 2 separate machines, for example. Do you have a household of 1 or 2 people? Buy a Miele washer dryer combination with a 7kg load capacity. If you have a household of more than 2 people, buy a 9kg model. A Miele TwinDos washer dryer combination automatically doses your detergent, so you'll never use too much detergent. That way, your clothing will look like new longer. PowerWash saves water and energy.
