Many bags of brand manufacturers have been already at about 1/3 full bag a significant loss of suction because of the fine dust clogged the pores of the bag. Not so with these bags for Sebo Felix. The bags are significantly larger than all the bags that I've seen so far (for other vacuum cleaner) and when the bag is filled to 2/3 (and there really much fits in), there are still no perceptible loss of suction, which in addition to the material presumably is due to the large surface area through which the air can flow. If there is to be a Dyson (the only viable Bagless), but a bag vacuum cleaner, a Sebo Felix is vermutich the best choice, if you like the retro design, but especially because of this ingenious bag.
