Our take

Dyson quotes 115 air watts and up to 50 minutes of runtime, and the sealed whole-machine filtration is the real reason to consider it if anyone in the car has allergies. What is harder to justify is the price. At $274.75 it costs four times the Fanttik and five times the Black+Decker, and it carries the same 4.2 rating the Fanttik does. Buyers are clearly getting something for the money, but the ratings do not show them getting four times more of it. It makes more sense if you also clean a boat or a caravan, which is what the kit is built around.

Best for: Households cleaning more than a car, including boats and caravans
