I've probably said this before but Sebo vacs beat Dyson hands down. Sure, they don't have the geek-appeal of the Dyson and from their website you can't really appreciate their ingenious but simplistic engineering. Oh, and I love the design-appeal of Dyson gear

Regarding the official testing: We (me and SWMBO) were all for buying a Dyson until 'she' got to try a Sebo. After trying two Dyson's and then a Sebo the Sebo was declared the winner

We now own one: It eats pet hair and its self-levelling thingy keeps it against the floor pretty reliably. Ok, it uses bags, unlike the Dyson, but given its superior cleaning ability it's worth a little extra on consumables IOHO.
