The Roomba vacuuming robot has been around for years keeping carpets clean, and I often wondered why they don't adopt the same technology for mowing grass?  Well finally my prayers have been answered, with the new SpyderEVO LawnBott.

This particular model is designed for the average suburban home using the same kind of technology used for Invisible Fences to mark the perimeter of your yard, this mowing machine can mow 3.5 hours on a single charge and with the optional docking station can recharge on its own.

Having the luxury of sitting back and never having to worry about mowing or bagging again does come with a hefty price, this model starts at $1,799 without the docking station, but there is some good news, on average the cost to run this cutting marvel is only about the cost of one tank of gas for your regular mower.
