>>814i think they were the first with the cyclonic bagless which was novel at the time but now its just normal
they never filter as well as a bagged and the filter always blocks up quicker
theyre also loud
the thing with modern bags is they are not just paper they are special polyester fabric that work a lot better and protect the final filter
miele's are made in germany and i used one once and it was pretty nice
i mean bags are a cost but not that much really
