Keeping with the automated robot theme, we found another little guy, however this guy is useful outside of your house. Automower, by which it's called, is something different than all the rest. This automated mower can recharge itself. First you set your yard boundaries with a wire system that tells the mower where the end of the grass is. Next you let it go. You can let the Automower mow and wander around 24 hours a day 7 days a week rain or shine. Once the Automower gets tired it will stop at one of it's recharging station around the yard and will get juiced back up. It snips off the top layers of your grass so your grass won't get too dry and allowing it to fertilize as it moves. It uses the same amount of power as a light bulb and is virtually silent.
