Is this likely to be the clutch that needs replacing?
It might just be one of the clutch belts that need replacing - would work out cheaper than replacing the whole clutch if so.
It's a cost vs. convenience scenario here really. If it's the brushbar belt that needs replacing (the more difficult of the two), it can be a bit of a fiddle but there are tutorials available on the web showing how it's done. A new clutch would pretty much just slot on in there!
Before you go spending out any money - does the brushbar spin freely?
