Since 2002, we suck with Miele appliances and have in the past several anther other manufacturers tried. Although some of them were not bad (there are huge differences in quality!), But we always come back to the Original Miele bags, because they have a higher degree of filling and must be changed frequently. That the suction power even when almost full Miele bag is still outstanding should not go unnoticed. Never us an original bag has burst, other manufacturers does. . When yearly requirement for an average household of perhaps 5-6 anthers a 4.5 liter capacity into perspective, the savings potential through purchase of third-party goods anyway to less than 1 euro per month - it is not worth it "to go foreign."
From me there is therefore a strong buy recommendation and 5 star review.
