We’ve evaluated the best robot lawn mowers for three years. In that time, we’ve considered dozens of models and compared their features, benefits and drawbacks. We believe the Husqvarna Automower is the best model because it is easy to operate, has an innovative blade system, and includes safety and anti-theft systems. It can cover .37 acres, which is more than enough for most residential homes. On a full charge, the battery lasts 70 minutes, then the machine automatically returns to its base to recharge before continuing.
