Now to me the second bag is already torn and the whole filth has spread in the vacuum cleaner. It works like this: First, the vacuum cleaner sucks (Bosch BSG81466) well. But gradually clog the pores of the dust bag. The pressure in the dust bag increases and the sachet tears - a crack at the non-woven seam, the other at the bonding to Pappadapter. The bags are simply not strong enough. Unfortunately, I have very many of them concerned (it should, two years range), but this bag I will not buy it again.
