The Solar Mower cuts your grass in a random pattern. This may sound like the perfect recipe for leaving certain parts of you lawn untouched, but as the Solar Mower begins working as soon as there is enough light to power it, it can roam up to 20 km on a sunny day. During this time, it has turned around lots of times, and every time it turns, it cuts in a random pattern that is not repeated. And remember, it cuts your grass every day. That means that every bit of your lawn will be cut every second day or so, as long as your lawn meets the requirements told about on the other pages on this site.
