The Miele WWE 660 W1 TwinDos automatically chooses the right quantity of detergent, so you don't have to adjust the dosage yourself. The washing machine does this automatically with TwinDos, a reservoir that's situated at the bottom of the washing machine. For special treatment of fabrics such as wool or silk, you can use a CapDosing laundry capsule. Simply put it in the hatch of the detergent drawer. With the drawer, you can also use your own detergent or fabrics softener. The washing machine washes 8 kilos of laundry very energy-efficiently with an A+++-10% energy label. Via the app, you can see exactly how long it will take for the cycle to finish. Ran out of detergent? You'll get an automatic notification on your smartphone or tablet, and you can order more using the app.
