eufy Robot Lawn Mower E15
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.

Our Verdict
The most hands-off setup on the list: pure-vision navigation skips both the boundary wire and the RTK antenna, and it adds the extras that matter for a robot left outside — built-in GPS anti-theft, rain auto-recall, and 3D obstacle avoidance. It ranks second rather than first because it costs noticeably more than the Navimow and its camera-only navigation is the most likely here to get confused on a complex or irregular lawn.

Alternatives to Consider
Segway Navimow i105N
Segway
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.
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.
