Yes but for the same argument's sake, the best Miele bag for the British pound is the bigger GN series, so you're spending more on either an outgoing S5 model to use that bag, or the cheaper S2 compromising on the lack of an internal tool storage and slightly longer cord and less power, to the new S8 successor model which is more expensive.
Therefore you could eliminate the S6 altogether for having the FJM bag which costs the same as the GN but losing out on the smaller dust bag capacity.
As highlighted before SEBO only make vacuums, so comparing another brand like Panasonic isn't really that fair - fine if it was Numatic - they and SEBO are together in terms of unique vacuum cleaner brands - after all they don't really make anything else that competes with the bigger brands, let alone Panasonic.
Frankly Steve, if you are of the opine that a thin synthetic dust bag that Panasonic supply (interestingly they share the same kind of consistency with both the K series, Felix and now new X bags) are not as good as multi layer, then you clearly don't know the mechanics of air flow and the mechanics of the vacuum cleaners in question.
Miele's vacuums have higher filtration layers because they've always done multi-layer and in some markets the AAC and HEPA filter cartridges are not available as single purchases. Therefore, lower models down the range only benefit from the Super Air Clean filter/standard filter and thus require the higher filtration layers to depend on.
SEBO's current synthetics have tightly packed layers that are not visible to the eye unless you cut the bag open and examine the layers in question. You'll have fun trying to pick it out amongst all the white fuzz, I can assure you!
Panasonic's synthetic dust bags actually have 5 layers of filtration. Coupled with the HEPA filter on board for a lower economical 1200 watt vacuum compared to Panasonic's standard (and May I just say) lower 3 ply paper bags for the 1900 watt uprights is more than sufficient.
You are trying to compare like with like, but what you forget is the high price of the SEBO K series, plus it being a cylinder vac with an air driven turbo brush at best or even the PN, means you're likely to spend more to actually buy the vacuum in question.
Though I paid £114 at the time for my Panasonic upright, the price of nearly 50% off now really isn't that much to moan about. I can't see any Miele or SEBO brand new going for £70, can you?
And whilst we are on the subject of synthetic dust bags, has Hoover launched any for their Purepower/Enigma uprights?
