Why vacuum for yourself when a robot can do the job for you? Competent cleaners like iRobot's Roomba series and Neato Botvacs will roam your halls and keep your floors clean so you don't have to. 

We haven't tested a robot vacuum that can match the power of a full upright, and the whole category of devices is pretty expensive, with prices ranging from $300 for older models to over $1,000. Still, the good ones can spot-clean well enough that you have a legitimate excuse to put off your own pass at the floors for a while longer.
