Anyone dismantled one of these, or know of any useful links? Had a bit of a Google, but there doesn't seem to be much advice out there. The brushes themselves and the filter are fine, I have dismantled the outer parts but can't see how to get into the brush drive gearbox for the moment. Since the literature says a blocked filter causes slow brushes it sounds like they are driven by a turbine from the vacuum, is this correct?
Anyone had good or bad experience with their service people?
TIA
