Hi. I work with spares myself, and was interested to hear you describe the cloth dust bags as being reusable. Would you say that's true for all types of cloth bags, such as the Numatic ones for their Henry models, and the Miele G/N and F/J/M types? Are users expected to just pluck the debris out of the bag, as there doesn't seem to be a way to open and close them otherwise... These are well-structured and basic videos, I'll be referring people to them for certain!
