We have had a DC02 for quite a few years, and the only thing that has failed is the mains lead inlet into the body.

The MAJOR failing of similar designs, is that it is an upright, and can, will, and does fall over, possibly breaking the handle (not that ours has yet). When I park the cleaner, I always have it with its back to the wall, so preventing damge should it tip backwards, as it is prone to do if nudged heavily.
