The vacuum cleaner bag from Swirl, M50 fit, seams or gaps in my Miele vacuum cleaners. Due to the high quality processing of these dust bags, the dust is trapped even with a nearly full bag not through the bag through, and from there into the device or possibly in the air. When removing the bag close again automatically after what works wonderfully and allows a clean disposal. No reason to complain and no rating trigger. Strong buy recommendation!
