I'm curious to this. They claim to "never lose suction" only a filterless Rainbow is likely to achieve this such as a D4, the Dyson filters will clog. Assuming you were to empty both basins when full the Dyson will eventually clog, the Rainbow will still work, probably without cleaning the seperator. Removes more dirt? I'd love to know the test methodology when it can't outclean a Fantom Thunder based on the same cyclone technology. The brush roller is not aggressive enough for certain carpet types.
I've got nothing against Dyson or the technology James Dyson developed (I own 4) but some of their advertisements are simply untrue.
