As far as I'm concerned nothing beats my little Roomba Robot Vacuum, since I don't have to do anything, but a hovering vacuum is something else. Now this technology is nothing new, Hoover made a floating canister vac back in the 50's and this is simply a modern update of a space-age classic. Check out the cool new and improved Hoover Constellation - Stainless Steel Hovering Canister Vacuum. This thing has everything you would expect from a good vacuum; HEPA filter, assorted brushes and tools, turbo power nozzle & a nice stainless steel finish, but it doesn't come with what you usually expect, Wheels! It uses a powerful 12 amp motor to not only deep clean, but to hover and float smoothly on a cushion of air. Everyone hates lugging around a vacuum through the house, this one is effortless. Pretty cool eh? Now, will someone please invent the Hoverboard already!
