You control a robot lawn mower with Bluetooth remotely with an app. You connect the mower via Bluetooth with your smartphone or tablet. You can adjust the settings from your home or garden, as long as you're within 10m of the robot lawn mower. For example, start or stop the mower without walking to it. That's useful if you just got comfortable. You can make mowing schedules, so the robot lawn mower does its job at the right moment. This way, the grass stays neat and short. Want to control your robot lawn mower from everywhere? You can expand some lawn mowers with a separate device, so it works with WiFi.
