### Instruction: How does a Husqvarna automatic lawn mower operate.
### Response: The Husqvarna Automower operates very similarly to a Roomba automated vacuum cleaner. However the main difference is that you have to lay down a wire perimeter about two inches below the lawn to guide it and it requires electrical power, usually low voltage. Once it is set up, the lawn mower can be scheduled to operate every evening on a schedule that works for you. It will cut about 1mm of grass per night and those cuttings will feed your lawn.
