Word on the 'net is that Electrolux is busy making houseshoes that double as vacuum cleaners... meaning you'll be able to walk around your house (or better yet, strap your kiddos into them, and let them run wild) until the place is spotless! There's no word yet on the functionality- like how the shoes will actually pick up and store the dirt, let alone power up, but it seems like a pretty novel idea. Link via Gizmodo.
