Hi - i found the forum courtesy of Manchester Vacs. They supplied me a new roller brush for Sebo x4 extra. The brush was/is tip top but i have figued out that the problem is the spindle won't rotate: lots of noise but no rottaion.
I found a video on the site about motor strip down... I'm thinking that the motor might be OK and the problem is with the drive.
Just ocurred to me that this should be a separate post, once i havce said hello. I'm pretty sure you'll tell me
... grateful for where i should post this
