It is very uncommon for a robot lawn mower to be stolen from your garden as there are a number of anti-theft features on most devices. Primarily, your mower may be fitted with an alarm as well as GPS tracking, so even if the person did manage to run away without you noticing, you would be able to locate the mower on your app. Moreover, a lot of robot lawn mowers require the user to input a PIN code, so even if they are stolen, the thief wouldn’t be able to use them. Most people know this and so know that stealing a robot mower isn’t going to be a lucrative crime.
