I can also testify that Dysons are one of the worst cleaners for losing suction after owning 4 of the pieces of that crap and use one in my part time job,
all different models suposedly improvements on the previous model and all have failed miserably.
Dyson did the only thing he could to make his cleaners look like they do something by using clear plastic bins and a cyclonic system that fluffs up dirt and triples it or more in volume.
While folk may fill their Dyson with each use the collected fluff is hardly compressed, which is why you empty the dust cannister so often.
Bagged cleaners compact the dirt hence why the bag dosnt need changing so often.
Im sure if bagless was the way then Miele would have used it a long time ago.
Not to mention that dysons brushrolls are useless at removing grit embedded in carpets.
Only today did I use my Miele cylinder in my part time cleaning job where I usually use a Dyson upright (which I also maintain regularly by washing the filters monthly or suction drops so dramtically)
The Miele literally wiped the floor with the Dyson and I ended up with 1/3 dustbag of grit and another 3rd of fluff.
Im now old and wise enough to know that a house cleaned with a Dyson is a dirty house.
~One day bagged cleaners will regain popularity when they are seen as a new and more hygienic way of managing dust.
BAGGED ALL THE WAY YEE HAW!!!!!
