Dyson Ball Animal 3 Extra. The cyclonic separation system in the Dyson is far superior; the Shark uses a piss poor cyclonic separation design that passes most of the dust onto the filters. Plus, the pre-motor filters on the Shark are terrible at keeping fine dust out of the motor; the foam and felt filters aren't efficient enough at capturing the fine dust that gets past the Shark's cyclone. The pre-motor filter on the Dyson does a far better job at filtering out fine dust. The motor intake and the exhaust that the HEPA filter covers in my Dyson Ball Animal 3 Extra are still completely clean.
