Installing a robot lawnmower used to involve crawling on your knees for two days to bury a "boundary wire." In 2026, wires are obsolete. The new generation of mowers uses satellites to know exactly where your grass ends and your flowerbed begins.
The market disruptor is the Segway Navimow H-Series, offering wire-free technology at a price that actually makes sense for homeowners. The undisputed king is the Husqvarna Automower NERA (with EPOS plug-in), a machine built by a company that has been making mowers for 100 years. Do you trust the scooter company or the forestry giant?
The Navigation: EFLS vs. EPOS
Both use RTK-GPS (Real-Time Kinematic), which is much more precise than the GPS in your phone.
Segway Navimow (The Value Visionary)
It uses EFLS (Exact Fusion Locating System) combined with a camera called VisionFence.
How it works: If the satellite signal gets blocked by a tree, the camera takes over to see the grass edge. It is incredibly smart at transitioning between open sky and shaded areas. You map the lawn by driving it around like a remote-controlled car via your phone.
Husqvarna NERA (The Precision Pro)
It uses the EPOS (Exact Positioning Operating System) module (sold separately or bundled).
How it works: It requires a reference station on your roof. The connection is rock-solid. It handles complex, multi-zone gardens better than any machine on earth. It can navigate narrow corridors that confuse the Segway.
The Cut and Terrain
Husqvarna Wins on Slopes.
The NERA series has a pivoting front axis (like a Jeep). It can handle 50% slopes without slipping. If your garden is hilly or uneven, Husqvarna is the only safe choice. Segway is better suited for flatter lawns (up to 45% theoretically, but struggles in wet mud).
Segway Wins on Edges.
Because of its camera and offset blade design, the Navimow cuts closer to the edge of the wall than the Husqvarna, leaving less work for your string trimmer (weed whacker).
🎯 Target Audience: Who is this for?
Buy Segway Navimow IF:
- You have a relatively flat, open garden without dense tree cover.
- You want great value. It includes the GPS tech in the box for half the price of the Husqvarna setup.
- You love gadgets. The app interface and "VisionFence" camera feed are very tech-forward.
Avoid Segway Navimow IF:
- You have a garden surrounded by very tall walls or dense forests (GPS signal might drop).
- You have rough, potholed terrain (it might get stuck).
Buy Husqvarna Automower NERA IF:
- You have a complex, hilly property with separate zones.
- You want a machine that lasts 10 years. Parts availability and dealer service networks for Husqvarna are legendary.
- You want it to work in pouring rain (it is built like a tank).
Avoid Husqvarna Automower NERA IF:
- You are budget-conscious (The mower + EPOS kit + Installation is very expensive).

FAQ: Does it run over toys?
