What, you’re supposed to get through a full 6-hour workday without gorging on a bag or three of cheese doodles? Of course not. But now there are orange crumbs all over your office floor. Problem solved with the Vroomba, the autonomous vacuum/roadster. With its 175 horsefly-power engine, just wind it up, let it go and watch it grind those crumbs deep into the carpet fibers so that they’re hardly noticeable anymore.
