Show the Power consumption on a full cottons load at each spin speed.
1200 rpm 3.15 kWh 100 mins
1400 rpm 3.00 kWh 97 mins
1600 rpm 2.75 kWh 89 mins
1800 rpm 2.70 kWh 88 mins

The Miele machines now set the maximum speed for a cycle, however you can select any speed below that, that you choose.
In Australia, 95% of dryers and non condensor and unvented. Most people discharge the exhaust air in the room and leave a window or door ajar. The filters are now as a rule good enough that very little lint makes it out into the room.
