Hi Sebo fan, which DC04 in green do you speak of? Only none of the DC04 range had clutches added - they all had them - but after a short while Dyson bought out a Dyson in grey & green which had the clutch removed. Well, what I mean is, it never had a clutch. You are right that certain tools were needed to change the belts on the clutch models (not to mention time) but the tools were not exclusive; just a few screwdrivers and star-heads, and a set of circlip pliers. Probably not the sort of thing your average Joe would own, but nothing out of the ordinary really.
