Can you mow the lawn in your sleep? If you have a Robomow Robotic Lawnmower, you very well could. Get this for your favorite lawn maintenance guru, and you'll all have more time to play on the weekends. Once the Robomow has been set up, it independently leaves its docking station, mows the lawn, and then returns to charge up for the next mowing. You can literally set it and forget it! Available on Amazon; $799.
