The Cinetic Big Ball, the one that has No filters to Wash or Replace' has TWO filters you DO need to REPLACE! They are located, one on either side, of the motor, i.e. the BIG BALL! Good luck finding them.
I run a well-established, 70+ brick & mortar warranty & repair center for vacuum cleaners. I do know that of which I speak. Dyson lies a lot!
Bottom Line: No, I would not recommend this to a friend
