Robot lawn mowers in Australia

Wire-free or boundary wire, how big a mower you need, and how they cope with Australian grasses.

The specs that matter

Spec sheets are full of numbers. These are the ones that change how the robot works in your home, with the units to look for.

Rated aream²: Buy a mower rated at least 30% above your lawn size. Ratings assume flat, open lawn.
Navigationwire · RTK-GPS · vision: Boundary wire is cheap and reliable but must be buried. RTK uses a satellite base station, no wire. Vision uses cameras and struggles with poor light.
Slope% or degrees: Check your steepest section. Many mowers handle 35–45%; wet grass lowers that.
Cutting heightmm: Buffalo and kikuyu like it higher than couch. Look for app-adjustable height.
Weather ratingIPX: IPX5 or better for summer storms. Many models return to base when the rain sensor trips.
SecurityPIN · GPS · alarm: Theft alarm, PIN lock and GPS tracking matter for front yards.

Do robot mowers work on buffalo grass?

Yes, but thick buffalo needs regular cutting and a higher height setting. Mowing little and often suits robot mowers.

Is RTK better than boundary wire?

RTK saves the install and lets you change zones in the app. Tall trees and buildings can block the satellite signal, so check your yard first.

Can they handle slopes?

Most handle moderate slopes. Very steep batters are still a job for a person with a whipper snipper.
