The Anthbot M9 is a robot lawn mower that can be controlled entirely from an iPhone, using RTK positioning technology instead of traditional perimeter wires. After testing for over a month, the reviewer found it has completely replaced manual lawn mowing, maintaining the yard like a "golf course" with zero effort beyond initial setup.

Setup requires less than 30 minutes - positioning the RTK reference station (which sticks into the ground with a forked pole), placing the charging station near a power outlet, and mapping the yard through the app. The robot detects rain and pauses automatically, can mow in darkness using headlights, and handles the reviewer's entire front and back yard from a single station.

Priced at $899 (currently $819 on Amazon or $769 directly), it requires no subscription. The only maintenance is flipping blades every 3-6 months and replacing them every 6-12 months ($19 for a 15-pack). The mower operates almost silently, lets you set custom mowing patterns and schedules through the app, and includes anti-theft alerts. For those with the budget, this robot eliminates lawn care entirely.
