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.
