I bought the machine in MM. These and many other machines from Bosch and Siemens in this price range have a drum structure that avoids problematic in my opinion, with laundry. The drum inside many small "pimples", flows through the water. Unfortunately, the edges of these studs are felt sharp. Already before buying I had concerns. After about 6 months now I always use more small holes fixed in my underwear. That alone TShirt what I'm wearing has 2 front holes, a total of more surely. In knitting partly arise even "nodules".
With my old machine I had never as good as holes in the laundry.
I will now try a washing bag, but the drum should I just not in machines for about 600 euros do the laundry broken.
