It's funny how bagless vacuums have been around for decades.
For example my aunt got Hitachi C-V160GN vacuum cleaner for wedding present around the mid 70's.
It had very large filter and filter had cleaning mechanism where you rotated the handle to clean it. It worked just okay. Most effective way to clean the filter was banging it against outside wall or something.
She still had it in the early 90's. Very good quality vacuum. She really liked it alot.
I don't remember any loss of suction problems or dust building up around other parts of the machine.
So there is alot of "cyclonic" vacuum cleaners out there that performs much worse.
