You can't keep Dyson's canister vac down

Dyson's rolling its newest vacuum innovation to the US. On display at the IFA trade show in Berlin, and on sale starting today at Dyson.com, the Dyson Cinetic Big Ball follows you diligently as you clean with the attached wand, and should it fall, it'll pick itself back up.

A vacuum that rights itself certainly sounds like science fiction, but Dyson keeps all components of the canister inside of a sphere with a low center of gravity. Should the canister get jostled and tip, it'll naturally work itself back to its upright position.

As usual with Dyson products, you'll need to pay an exorbitant price to take advantage of this cool feature. The Cinetic Big Ball costs $600 or £450. Again, it's available today at Dyson's US and UK sites. In Australia, it's available in a bunch of different models starting at AU$699. Starting September 18, you'll find it at major US appliance retailers.

If you're in the UK or Australia, the self-righting Big Ball is already on sale. Dyson introduced it in those markets, where canister vacuums are more popular, back in April. It's £450 in the UK and AU$1,000 in Australia.

Like the Cinetic Big Ball Animal Allergy we reviewed last year, the new Cinetic Big Ball ditches the need for a filter. The Cinetic technology breaks down dirt as it sucks it in, so you don't need to hassle with filter maintenance and it never loses suction. I was skeptical of this innovation when Dyson debuted it a year ago, but after rigorous tests, I'll confirm Dyson Cinetic tech works, and it's cool.

Between the filter free approach and the canister that takes care of itself, the Dyson Cinetic Big Ball might have enough going for it to convince Americans to give up their uprights. The price, though, is still a lot to stomach, and the one sticking point we've been unable to justify in all of our Dyson reviews to date. Maybe this vac can change our minds when we put it to the test for a full review.
