Review on 👜 LINNIW 20 Packs 3D Airclean GN Bags for Miele Classic C1, Complete C1, C2 - Compatible with S227/S240, S270, S400, S2, S5, S8 Series - Includes 5 Set Air Clean Filters by Kelly Zitzner

I tried two bags, came out the same, there was more dirt in my vacuum than in the bag. It is obvious that the valve in the opening of the bag is not working properly, it could ruin a VERY expensive vacuum cleaner. Although it is written that they are for me, they do not work. As I sucked, I noticed it wasn't sucking as well as it normally would, and then it started sounding like he was struggling to open it to find the mess. Tried another bag, same thing. After vacuuming the inside a second time I put an actual Miele sack inside and it worked great! Everything back to normal, no problems. Lesson learned: It's better to just pay the price for a genuine Miele bag than risk ruining an expensive and great vacuum cleaner.
