You may think that the world's most expensive vacuum would be a Dyson or some other high-tech cleaning contraption, but that's apparently not the case, at least according to the vacuum authority that is the Guinness Book of World Records. No, the world's most expensive vacuum is apparently this otherwise ordinary Electrolux, which has been adorned with 3,730 Swarovski crystals by Polish designer Lukaz Jemiol and now commands the princely sum of £13,825 (or just under $20,000). That may not help the vacuum's cleaning ability much, but it'll certainly help it hold its own against all the other Swarovski-encrusted products out there, which, last we checked, includes everything imaginable. Better act quick if you're looking to add to the collection though, as this one is strictly one of a kind.

Electrolux has never been one to cling to the usual household appliance conventions, and it now looks to be pushing beyond 'em once again with its new "auto-focus" Inspiro oven, which promises to automatically pick the proper cooking settings based on the contents of the oven. That's apparently done with an array of sensors that determine the exact combination of energy consumption and time needed to bring food to the correct temperature, which Electrolux describes as working in much the same way "cameras now automatically set aperture, exposure time and focus, depending on the light and what's in the frame." Of course, those that like to feel that their smarter than their oven can also make use of a manual mode, although it's not clear when they'll actually be able to do that, with no word on a release date (or a price) just yet.
