While it will set you back around $2,000 (€1,559), the Robby Garden XP robotic mower has some unique features that somewhat justify the price. Unlike other robomowers which require you to install a perimeter fence so it doesn’t wander into flower beds, gardens and children’s sand boxes, the Robby uses a grass sensor to distinguish between your lawn and other areas you don’t want shredded. Apparently it’s not perfect, and works best when there’s a distinct separation between grass and garden, like a row of decorative rocks or shrubbery, but it’s better than having to lay underground wires.
The Robby Garden XP also shreds and mulches the trimmed grass as it roves your property, essentially creating a fertilizer that should in theory help your lawn flourish. And to conserve battery power the grass sensors are also able to tell how tall the grass is, automatically adjusting the speed of the cutting blades when there’s less work to do, which also makes it less noisy. It seems pretty safe too, since simply touching the mower will automatically stop the cutting blades, and a single button on top allows you to easily turn it on or off at any time.
