Yes my Vax is like this, the brush bar simply has a kind of paddle

does not turn the brush due to crap in the bearings after a while
reducing the suction as well. There are screws in my head so I removed
them, cleaned out the bearings but however I put it back together it
was never as free as when it was new. I bought a second one and
itsuffered the same fate, so I bought a more sensible vacuum, a Bosch
and a Henry, neither have brushes but seem not to need them as the
suction is ten times better.

I think you're referring to the brushbar in the mini head that attaches
to the hose (gave up on that long ago!)
What I'm talking about is the large brushbar in the main cleaner head
that is driven by a toothed belt connected to the motor.
Most Vax models seem to have this at the end of the brushbar and a
removable cover to service it, but this model's drive belt is near the
middle of the bar, as I've seen on Dyson uprights. But the Dyson
brushbars I've seen can easily be pulled out. Apparently not this one

I found it works quite well, especially on stairs, but does need attention
regularly to clear hair from the bearings.
