For years I bought Miele vacuum cleaner bags for my vacuum cleaner. I tried these bags hoping that it fits very well and the only thing is that the full indicator automatically turns so red as if it was full. I have to check from time to time. But considering the price compared to Miele bags I willingly make the effort. Nothing said about the bags, they are thick there even exchange them for small filters. I have a Miele vacuum cleaner Cats and Dog.
