Earlier this year, I replaced my battery-powered push mower with an iPhone-controlled robot lawn mower. That machine creates a virtual map by letting you manually steer it around the perimeter of your yard. Once everything is configured, it takes over mowing duties on a schedule.

More recently, I’ve been testing another system called the TerraMow V1000. It takes a substantially different approach to navigation, and after several weeks of testing, I think it may be the more user-friendly option for a lot people.

The biggest difference between the TerraMow V1000 and the Anthbot M9 I reviewed earlier this year is how each machine understands your yard.

Anthbot M9 uses an RTK reference station for positioning. Its setup process had me manually steering the mower around the perimeter from my iPhone to create the initial map.
