Low cost RTK and camera mower for small, flat lawns
Researched by Riley Hart · updated Oct 30, 2026
Is the Anthbot M9 worth it? The M9 is one of the cheapest RTK mowers with camera obstacle avoidance, and both testers found it quiet, easy to set up and neat on a tidy lawn. It costs $699 as of Nov 4, 2026, and 2 independent reviewers tested it.
The M9 is one of the cheapest RTK mowers with camera obstacle avoidance, and both testers found it quiet, easy to set up and neat on a tidy lawn. It struggles in thick or tall grass, leaves a border strip and can lose its way after a mishap. Buy it for a small, flat, well kept lawn; skip it for rough or overgrown yards.
Best for: small flat lawns on a tight budget. Skip if: your grass is thick, tall or hilly.

What independent reviewers found
- Tested in Maine alongside a Lymow One Plus. Quietest mower the reviewer tested at about 60 dB at 1 m; setup took about 20 minutes. Stalled on thick, tall or wet grass, left a 15 to 20 cm border strip, lost position after driving off a ledge and could not dock. Expert score 82.
- GadgetReview · 85 True Score
- Hands on test found setup took about 10 minutes as claimed, tight turns and straight lines, and no trouble with shadows or a clothesline pole. A test section used about 10% of the battery. Thick, stubborn grass got a less even cut; not suited to overgrown lawns or yards with roots.

Questions buyers ask
Is there a subscription?
Only if you use NetRTK over 4G. GadgetReview reports $39.99 a year after the free trial. The included RTK base station works without it.
Can it cut overgrown grass?
Not well. GadgetReview says the app advises getting the lawn under 7 cm first, and both testers saw it struggle in thick grass.
Does it mow to the edge?
No. GadgetReview found a 15 to 20 cm band left uncut along borders.
