Typical, heavier cottons loads aren't really an issue.
LG has that "speed bump" kind if design in the new machines and as long as laundry is heavy enough to have enough friction between drum and itself, the centrifugal forces are enough to lift the laundry up enough to at least tumble the loads.
Once you get smaller loads or lighter items (like curtains, etc.), the weight of the laundry is so small that friction between drum and laundry gets so low you need really high drum speeds to have any effective laundry movement.
And if the items you want are delicate, you can't really use those high speeds.
And then you are SOL.
You could often compensate for that in certain ways, like higher water levels, so you could fast drum movement and still get relatively gentle washing.
But it doesn't sound like Miele would do that.
