Frequently asked questions

Do I need to install a boundary wire?

Older mowers use a perimeter wire; newer wire-free models use RTK-GPS and/or vision to map the lawn — check the navigation spec above.

Can it handle slopes?

Yes, up to the max-slope rating shown. All-wheel-drive models climb the steepest inclines; standard models handle gentler grades.

Is it safe around kids and pets?

Robot mowers have lift/tilt sensors and bumper stops that halt the blades instantly, plus PIN locks and theft alarms.

How big a lawn can it mow?

See the coverage spec. Most models cover their rated area on a single charge, then return to the dock to recharge and resume.
