The s2 appears to lack the dust chamber edge sealing that the s5 offers, among other things.
Also, as an aside, it seems the HYCLEAN bags have fixed the S5's previous problem of dust leaking through its bags and clogging its HEPA filter, the main reason I've stuck with the Blue Moon for awhile.
Have to admit the S5 maneuvers better than the Blue Moon, though.
Probably true but what about the inner side of the lid on the top where the hose mount is located? The seals may have been put up there that close down onto the bag once the lid is locked down.
The Hyclean bags have been improved - this was already identified in an earlier post where some U.S places are getting "Airclean" bags rather than "HyClean" and in the UK Miele haven't bothered to change the name , only getting rid of the central inner ribbons that pushed dust out past the seal hole.
