Here is a little more information I lifted from a Web page. haven't edited it as thoroughly as Ray does.
For more information, Google is your friend. Top Rated What the Research Says . Lawnbott Evolution (*est. $2,500) >> Where to buy Best robotic lawn mower. The Lawnbott automatic mower can handle lawns up to about 3/4 acre (or twice that if a second battery is added), automatically recharging itself whenever needed. Reviews say this is the most sophisticated robotic mower available, since it's able to program itself to keep your lawn at your favorite cutting height. Once you run wires around the perimeter of the mowing area, this automatic mower rarely needs any human intervention. The Lawnbott Evolution robotic mower is small, sleek, and lightweight at 22 pounds, so it fits into tight spaces and is easy to handle. An included remote control allows you to steer it through tight spots. Its lithium-ion battery, unique among automatic mowers, is long lasting and environmentally friendly. The Lawnbott has a two-year warranty. . Friendly Robotics RoboMower RL1000 (*est. $1,600) >> Where to buy For half-acre lawns. The RoboMower RL1000 handles lawns up to about half an acre. Reviews say that using optional low cut blades (*est. $65), the RL1000 mower mulches fall leaves better than the Lawnbott Evolution. However, the RoboMower RL1000 is noisier, heavier and cuts more slowly. It can handle more than one zone, but has to be guided to the starting point with the remote control. You also have to program it to mow on the schedule you select, giving the lead-acid batteries time to recharge overnight. A 6-hour fast charger is an option (*est. $155). The RoboMower isn't as convenient as the Lawnbott Evolution, but it costs almost $1,000 less and comes with a two-year warranty. (compare prices) . Friendly Robotics RoboMower RL850 (*est. $1,200) >> Where to buy Best automatic mower for smaller lawns. The 21-inch RoboMower RL850 is similar to the RL1000, but doesn't drive itself to the starting point or return to its charger automatically after it finishes mowing, and the mowing times can't be programmed. So you have to use the remote control to guide it to the starting point, let it mow, then guide it back to its charger. The RoboMower RL850 is designed for yards up to about 10,800 square feet.

Now that retailers like Sears and Wal-Mart are carrying them, robotic mowers have hit the mainstream. Also called automatic mowers, these lawn mowers are designed to save time and effort, not only for people with disabilities, but for anyone who wants to use their time for something other than mowing the lawn. Robotic mowers can only mulch clippings; they don't side-discharge clippings and can't be used for bagging clippings. Standard gas-powered mowers, electric mowers and manual mowers (which cost far less) are covered in our main report on lawn mowers . Riding lawn mowers are covered in our report on lawn tractors . We found the best review of robotic mowers on a retail site, Bamabots.com, where Kerry Clabaugh provides in-depth reviews of the two main competitors, the RoboMower RL1000 (*est. $1,600) and the Lawnbott Evolution (*est. $2,500) along with a detailed comparison of the two. An older comparative review at Popular Mechanics compares two other robotic mowers, including the third main competitor, the Husqvarna Auto Mower, but doesn't document any testing.
