I'm sure some of you have looked at robo mowers as Roombas for your yard but, sadly, many of them require you to install a boundary wire around the perimeter of your lawn. And any product that requires you to dig a trench is the opposite of what "low effort" means to me. That's why I was interested in trying Segway's Navimow i105, its 945 (around 1,200) GPS-equipped mower which eliminates that busywork. And keeping your lawn neat and tidy is a job that's all busywork. Ask a gardener and they'll tell you the secret to a great lawn is to seed a piece of flat land and then mow it into submission.

Segway is moving into the robot mower market with the Navimow. What sets this model apart from many others is that you don't need to install a boundary wire. Instead, Navimow uses GPS and other sensors to stay within the perimeter of your lawn. A so-called Exact Fusion Locating System can maintain Navimow's position accurate to within two centimeters, according to Segway. If the GPS signal ever dips, the company says the device's array of sensors and data ensure it will still work.
