Segway Navimow i105N
The best all-around robot mower for a small yard, and the easiest to justify at its price. The Navimow i105N combines RTK positioning with a 140-degree VisionFence camera for wire-free setup — you walk the boundary once with your phone instead of burying a cable — and its AI can recognize 150-plus types of common garden obstacles. For a compact lawn up to about a quarter of what its bigger siblings cover, it delivers the modern wire-free experience without the flagship price.

Our Verdict
The best balance of convenience, capability, and price for a small yard. The i105N is fully wire-free — RTK plus a 140-degree VisionFence camera let you map the lawn by walking the boundary with your phone — and its AI recognizes 150+ obstacle types rather than bumping into them. At its mid-tier price it undercuts the other wire-free picks while covering everything a compact lawn needs, which is why it takes the top spot over the more expensive eufy and Mammotion.
Score Breakdown
Pros & Cons
Pros
- •Fully wire-free RTK + Vision setup — no perimeter cable to lay

Cons
- •RTK relies on a clear sky view — heavily wooded lots can lose signal
- •GPS anti-theft tracking requires the optional 4G add-on module
- •Covers small-to-mid lawns, not large properties

Alternatives to Consider
eufy Robot Lawn Mower E15
eufy
The most hands-off setup here, and the pick for buyers who want to skip both boundary wires and RTK antennas entirely. The E15 navigates by pure vision — eufy's V-FSD 1.0 uses stereo cameras and AI to see, map, and mow on its own — and layers on the extras that matter for a robot left outside unattended: built-in GPS anti-theft, automatic recall in rain or low light, and 3D obstacle avoidance. It costs more than the wire-free RTK models, but it's the closest thing to a set-and-forget robot for a simple small lawn.
Gardena SILENO City
Gardena
The value pick and the quietest robot on this list. The SILENO City is a boundary-wire mower — you lay a perimeter cable once during setup — but in exchange you get German build quality, a class-leading 57 dB(A) noise level, and patented streak-free navigation that handles narrow passages and tight city-garden corners reliably. It's the least expensive mower here and the one to buy if you don't mind an afternoon of wire installation to save money and get a proven, low-drama cut.
Mammotion LUBA Mini AWD 800
Mammotion
The premium pick, and the one to buy only if your small yard has real slopes or rough terrain. The LUBA Mini AWD 800 is an all-wheel-drive robot that climbs gradients up to 80% — far beyond what any other mower here attempts — using RTK plus Mammotion's UltraSense AI Vision for wire-free positioning even under trees. It also carries the most complete feature set: 20-zone management, 4G/Bluetooth/Wi-Fi connectivity, and built-in GPS anti-theft. For a flat, simple small lawn it's overkill; for a compact but hilly or uneven one, nothing else on this list keeps up.
Worx Landroid S WR165
Worx
A boundary-wire small-lawn mower whose best argument is the ecosystem around it: its 20V 2.0Ah Power Share battery is shared with every other Worx 20V, 40V, and 80V tool, so existing Worx owners get a robot mower that plugs into batteries they already own. The Landroid S uses a patented AIA algorithm to thread narrow passages and a floating blade disc for clearance on uneven ground. It lands last here because it has no camera obstacle avoidance and, like other bumper-based mowers, can get hung up on rough terrain — but for a clear, simple small lawn it's a capable, brand-consistent choice.
