TurfNav is buying intelligence for robotic lawn mowers — navigation, fixes, and parts, without the sales pitch. Spec-by-spec comparisons across the $999–$5,000 range, symptom-first troubleshooting, and the blade, battery, and winter-storage protocols that decide whether a mower lasts.
Read the 2026 Buying Guide My mower lost its place — start hereMost robot-mower content is a ranked list written to sell you something. Ours is organized the way owners actually think: Which one fits my yard? Why did mine stop knowing where it is? How do I make it last?
Mammotion, Navimow, Husqvarna Automower, Worx, ECOVACS and more — compared on the specs that actually eliminate options: navigation fit for your trees and walls, coverage vs. real daily throughput, slope ratings converted to both % and degrees, and the 5-year parts bill.
"No loop signal," flashing yellow lights, "antenna moved" errors, docks that won't charge. The positioning-failure family — the category's #1 stop-work fault — diagnosed in order, cheapest and most likely first, for both wired and wire-free machines.
Razor-blade cadence, battery storage charge, contact care, and the winter-storage protocol — including the cold-garage-at-0% mistake that kills more mower batteries than mowing ever does.
Pools had corded vs. cordless. Mowers have a four-way split, and it decides what you buy, how it fails, and what it costs to keep. This is the category's mental model:
| System | How it bounds the lawn | Signature failure modes | Who uses it |
|---|---|---|---|
| Boundary wire | Buried or stapled loop wire + guide wire; the station drives a loop signal | Wire breaks, corroded couplers, "no loop signal," interference near metal or buried cables | Husqvarna Automower (classic), Worx Landroid (classic), Gardena |
| RTK-GNSS | A local antenna/reference station + satellite fix, centimetre-level | Weak or lost fix under trees and near walls, antenna siting errors, "antenna moved," multipath drift | Navimow (EFLS), Mammotion LUBA 2, Husqvarna EPOS, Sunseeker |
| LiDAR / vision | 360° LiDAR and/or cameras; no antenna, no wire | Low-light and featureless-lawn drift, dirty sensors, mapping errors | ECOVACS GOAT, Dreame, Mammotion LUBA 3 (fusion), Navimow i215 (fusion) |
| Cloud / network RTK | Correction data streamed over 4G/internet; no home antenna | Connectivity dependence, coverage gaps | Worx Vision Cloud, Mammotion NetRTK, Navimow X4 |
Two buyer-confusion facts we build on: brands mix slope units freely — 80% is 38.6°, Husqvarna's 45% is 24.2° — and coverage ratings are maximum-area figures under ideal conditions, not the smaller daily throughput your lawn actually gets. Every TurfNav comparison normalises both. The buying guide runs the full elimination.
Free articles get you oriented. The paid guide goes all the way: the full eliminator system worked for your yard, model-family shortlists with the specs that rule each in or out, and 5-year total-cost tables. Priced below one professional wire installation ($850–$1,000) — and below the cost of buying the wrong navigation system once.
A configurator-style buying system: navigation fit by tree cover and sky view, coverage vs. daily throughput, slope in normalised units, cutting system and edge behaviour, and parts/service channel — with model-family shortlists and a 5-year TCO table per finalist class. Chapter 1 (the navigation eliminator) is free inside the buying guide.

It's October — this is the one job that can't wait for spring. Storage charge levels by brand, indoor storage rules, what to do with the station, the wire ends, and the RTK antenna, and the spring recommissioning checklist.
Read the station first, then work the wired path, the RTK path, and the vision path — including the AM-radio wire-break trace and the idle-voltage trap that makes a dying power supply read healthy.
Ragged grass tips mean dull razor blades — the #1 owner-discovered maintenance fact. The full cadence table: blades, batteries, wire, docks, and what each costs per year.
One short email when it matters: new model releases and price moves in the $999–$5,000 band, seasonal reminders (winterize, spring recommissioning, blade cadence), and new troubleshooting guides. No daily spam, no selling your address.
