I just wanted to add that, although they look really similar, the dc02 and fantom have very different filtration systems. The fantom lightning has a smaller, single entrance inner cyclone, no pre motor filter aside from a metal mesh screen, and the post filter is different. You can see where fantom modified the plastic molds to make these modifications. As a result of these changes, none of the parts or filters are interchangeable. As was quoted above, fantom did this to make the post filter (and consequently the motor) to load up with dust faster.
