room on their own? I've got a project to do involving me creating an advertisement for a useless product, and this came to mind. If you need more explanation I believe the vacuum was on a television infomercial at one time, and it looks like a small saucer. It will continue to move across your floor without any assistance and vacuums as it goes. I'm not sure if there were multiple versions of this thing, I'm just looking for one name or brand that has it.
