A new synthetic bag which lasts up to 50% longer than a normal paper bag. If you continue to vacuum with a bag that is over half full, your cleaning efficiency will soon be reduced. Not so with our new generation of synthetic dust bags. The bags are specially designed to provide long-lasting vacuum cleaning performance up to the moment the dust bag is full and ready for disposal. And now, thanks to its new innovative folding, its capacity is 15% higher than a flat synthetic bag!
