We imagine anyone who buys a robot lawnmower already has a great lawn to run it on, but what if your tract of grass is wilder than normal? The $3,000 Lymow One could be what you’re looking for. Not only is it outfitted with tank-like tracks — called, no kidding, the Savage Traverse System — it includes mulching blades that are strong enough to macerate leaves, fruit, pine cones and small branches. A centrifugal fan disperses the matter and prevents clogging. Your curious pets should be safe, though, because the Lymow One has obstacle recognition and avoidance tech.
