Dyson with a difference.....

I have found the later DC07's to be good with filtration. DC01's dont really let hair get to the filter, just dust mainly.
My DC14 lets dust and hair get to the filter, and it's quite annoying and I do agree with Blakaeg here regarding the Dual cyclone and root cyclone technology to be equal in filtration

One reason the DC03 had good separation was because the bin was comparatively tall, so the whirling dust at the bottom was well out of the way of the shroud. Contrast that to the DC05, for example, which had a rather squat bin. On mine, the odd clump of dust and hair would often glom onto the shroud during use, and some would inevitably make its way through, which probably explains why the pre filter tended to soil more quickly than I would have liked.
