I regret to say directly: The tensile strength of the bags is niht very good. I have the vacuum cleaner with the filter bags used and unfortunately have to remove 1/3 filling an open "something" out of the suction tank each of the first four sacks at ca solely for accumulating dust and chips. Therefore Conclusion: dustbag as "dust bag" used but not as Tasächlicher coarse dirt bag
