Well what should I write here? The bag corresponding to the printed design 1: 1 the bag was used in our new Siemens VSZ-3B21 ex works. As our new sucker a so-called. ECO model of energy-Eff. Kl. A is with only 600 watts input power, we had the efficiency of the bag and especially important with increasing degree of filling of the then most threatening Saufkraftverlust. The acquired here Original BSH bag disappoint in this regard at all, rather the bag is changed times ahead because of the increasing with increasing level odors. With an empty bag on the vacuum cleaner is sufficient already to the entire budget to get perfectly clean and even if the bag is full, I had never turn up until it stops half the power. Only one question remains why our last Philips Eco-performer (the thing was really so) 2.400Watt power input for in the end had to have the same suction result.
