I just picked up a fairly clean DC25 All Floors for £20. It was advertised as all working OK except having a jammed wand, which it did-the usual issue with these. However on stripping it down to clean, I found the HEPA post motor filter to be absolutely black with carbon; impossible to wash all of it out, so have ordered a new filter.
The main motor appears to be working fine, along with the brushbar motor, so I can only assume that the motor was replaced, but the HEPA was not changed at the same time. Or is the motor about to expire on me?
Not sure which year the DC25 was released, but quite likely that it was a warranty repair, so how come the HEPA wasn't changed as well?
This is the first ball model I've had, so will reserve opinions on it for now.
