These fit well into the vacuum cleaner and do their job the way that is provided and can be good and relatively dust-free fountains remove afterwards. Otherwise, do not provide benefits, such as over competing products. Inherent in them is only just the disadvantage that it requires just over the main bag. As long as our brave little vacuum cleaner Siemens still holds out (so far already more than 15 years), it is still used along with the bag. After that there will be a bagless Dyson, who has no disadvantages to the high price. Since the bag but nothing for the beutelbenötigende system can and here in packs of three and are much cheaper than in retail, you can just but only satisfied. Therefore, full marks.
