ANTHBOT M9 Review
The balanced choice in the ANTHBOT range: 1,000 m², full-band RTK with a vision backup, equal charge and mowing windows, and the strongest anti-theft set in the family.
- Full-band RTK plus network RTK with dual 150° HDR cameras
- Rated to 1,000 m² (1/4 acre) with 30 zones on the manufacturer table
- 90 min mowing per charge against a 90 min charge time
Best for: Mid-size lawns up to a quarter acre · Specifications last checked September 24, 2026
Overview
The M9 is the sensible middle of the ANTHBOT range. It is rated for 1,000 m² — a quarter acre — and its headline balance is unusual in this category: 90 minutes of mowing for 90 minutes of charging. Most machines here either charge faster than they mow or mow much longer than they charge; this one is matched, which makes its schedule predictable rather than lumpy.
It positions itself the conventional way for this generation, with full-band RTK backed by network RTK and two 150° HDR cameras. The cameras matter when the satellite view fails: under a canopy or tight against a building, ANTHBOT switches to visual positioning rather than stopping. The RTK reference station is included in the box, unlike the Navimow i105N where the antenna kit is the setup task you inherit.
Two caveats worth knowing before you buy. ANTHBOT publishes 30 mow zones for the M9 on its comparison table but 20 on the product page, and we print both rather than choose. And the 45% slope ceiling, shared across the ANTHBOT range, is the middle of this field — enough for most domestic lawns, well short of what the Mammotion or ECOVACS will climb. If you want the shelter for the dock, the same machine is listed separately with it.
More angles
More from the manufacturer's product listing. These include the brand's own annotated graphics as well as plain product shots. We reproduce them unaltered, so any performance figure printed inside an image is the manufacturer's claim — it is not a measurement of ours, and it is not why a model ranks where it does here.

Pros
- 90 min mowing per charge against a 90 min charge time — an unusually even cycle
- Full-band RTK with network RTK and dual vision, with the reference station included
- Three-year warranty with the fullest anti-theft set in this comparison
- GPS tracking, out-of-boundary alarm and Find My as standard
- 1,000 m² rating with up to 30 zones on the manufacturer table
- Lighter and smaller than the N8 and every competitor except the Navimow
Cons
- The manufacturer publishes 30 zones on one page and 20 on another for the same machine
- 45% slope ceiling is mid-field, and half of what the Mammotion claims
- 150 m²/h is below the Mammotion and ECOVACS coverage rates
- Only three months of 4G included, where the N8 includes a year
- The listing title and its own description disagree on lawn size, stating both 1/4 acre and 0.3 acre
- No self-emptying bin, so it is a mulch-only machine
Who it's for
- Lawns of about a quarter acre with several distinct zones
- Anyone who wants RTK accuracy with a vision fallback for tree cover
- Buyers who want anti-theft tracking as standard rather than an add-on
- Households that value a predictable charge-to-mow cycle
Who should skip it
- Lawns beyond about a quarter acre, where the N8 or ECOVACS cover more
- Steep ground beyond a 45% gradient
- Anyone who wants clippings collected or a bin that empties itself
- Buyers who need a confirmed zone count before purchase
