Hear hear, if Bagged cleaners go all together, I think I'll lose all faith in modern manufacturers.
As for Miele and Numatic, I am certain they will NEVER expand to Bagless technology, as they have both built up such a magnificent reputation for making good Bagged Vacuum Cleaners and by banishing them they would ruin their businesses.
Isn't it strange though, that (with the exception of the aforementioned brands) Bagged cleaners are getting worse as time goes on, with the best ones being from 20 odd years ago ?
You would think it would be the opposite, but it seems not.
On the other hand Bagless cleaners are getting better (in terms of suction sustainability).
It actually makes sense if you think about it.
They are spending less time making Bagged cleaners as good as they used to be, whereas they are spending a lot of time making Bagless cleaners better, for one purpose only. To subtly try to forbear people from buying Bagged cleaners, so they can have an all Bagless market to make things more modern, which is what everybody seems to want to do these days.
I however, shall never proselyte. I believe old technology is the best for the most part - An opinion that I will take to my grave.
