Maybe called the "Green Machine", this is a low-tech human- powered vacuum cleaner that uses pedal power both to drive a fan which sucks dirt through an aimable nozzle, and motivates the unit like a tractor-mower.

       Even more fun - can you make me a pogo stick version? (+)

       The most likely problem with this Idea is that electric motors in vacuum cleaners are far more powerful than mere humans (say 5 horsepower vs 1/3 HP). To compensate, the sucking end of the vacuum would have to be perhaps 1/15 the area that they normally are.   

       Worse, humans can't maintain 1/3 HP output for very long, so you need an even smaller suck-area of the vacuum, to allow a more leisurely and longer-lasting effort. Perhaps a 20 times longer-lasting effort, to vacuum a carpet....

       I read this in the professors' voice from Gilligans Island.   

       Afraid I have to bone this, for the reason explained by Vernon above. There just isn't enough power.

       Ha! I can't get my wife to vacuum or ride a bike. You want her to do both? [+] for being optimistic As for having enough power just add a battery and a voltmeter that tells you when you have 5 min worth of vacuuming stored. Too bad this can't be powered by my wife's ability to watch TV while reading.

       Legislate a limit on the power of electric motors in vacuum cleaners. That'll teach'em.

       Brian, in my house the men do the vacuuming and the cycling.
