A 29-cm cutting disc and two lithium batteries, the capacity to mow surfaces of up to 3000 sqm, even on slopes of 45%. The Runner XK model offers outstanding performances in terms of reliability and resistance; its special sensors recognise when the grass has been already mowed, thus allowing the robot to return to its station without wasting energy and, above all, preventing unnecessary wear and tear. The two lithium batteries grant power and reliability, while an alarm system makes this one of the most evolved robots in its class. Its facilities make this model the top of the range.
