Mine is a Friendly Robotics Robomow RL-2000. Friendly Robotics is an Israeli company. They know robotics.
I actually have several. I don’t know why everyone doesn’t have one. I work on other things while the robot mows the lawn.
Maybe some are afraid of the robot uprising and having a robot armed with blades in your backyard is enough to frighten them away?
Or the cost is really high and it’s tough to afford for many on something like this.
