We operate as before a Siemens 915 class vacuum cleaner from the 90s. Since the now sold by Swirl S64 Mikrofaserbeutelchen not fit 100% (must be buckled), the suction power is modest and the bags are exorbitantly expensive for their capacity, I have tried this on the off chance the paper bag here.
They are originally sold for the model original bags in every way, the total volume of the suction box is usable again and the suction power available until the end.
