I agree with you, Atheist. We have a Vax bagless machine which is lovely to use but needs emptying after every use. On the adverts , you just open them up and all the debris just drops out into the bin. That is not so! You have to literally scrape it out into the bin and, consequently become enveloped in clouds of dust! Horrible.
However, the convenience and ease of use or the the machine overrides the mushroom cloud of dust. I just try to stand back or get Mr T to do it. :-)
