All robot lawn mowers. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | Automower 405XE NERA | Navimow i2 LiDAR Pro |
|---|---|---|
| Yard size | ||
| Under ¼ acre | Good405XE NERA handles sub-0.25-acre yards efficiently; setup time under 2 hours; full coverage per mow cycle. | GoodSegway rates the i210 for 1,000 m², about a quarter acre, and Notebookcheck tested it on 300 m². |
| ¼ – ½ acre | GoodDesigned for 0.25–0.5-acre range. Manufacturer specs document full coverage in single runs at this scale. | GoodSegway rates the i220 LiDAR Pro for 2,000 m², close to half an acre. |
| Over ½ acrethey differ | DependsOver 0.5 acres requires longer run times and mid-cycle returns to charging station. Coverage may need multiple days or extended schedule. | PoorLawns over half an acre exceed Segway's 2,000 m² rating for the larger i220 LiDAR Pro. |
| Terrain | ||
| Mostly flat | GoodFlat or gently rolling yards are ideal for EPOS and wheel traction. No slope-related coverage issues. | GoodNotebookcheck saw straight paths, full coverage and an even cut on open lawn. |
| Gentle slopesthey differ | DependsRated to 25% gradient. Owner reports suggest traction loss above 20% on wet grass; performance degrades in rainy seasons. | GoodAll-wheel drive and front-wheel steering gave Notebookcheck's unit off-road capability on uneven lawns. |
| Steep / hillythey differ | PoorSlopes above 25% exceed manufacturer spec. Steep terrain causes wheel slip, uneven cutting, and increased motor strain. | DependsIt climbed a 55% artificial-turf ramp for Notebookcheck, but no test on real steep grass was found. |
| Grass type | ||
| Typical lawn grass | GoodStandard cool-season and warm-season turf are the design baseline. Manufacturer specs confirm reliable mowing on common lawn grasses. | GoodNotebookcheck found the cutting deck produced an even cut on open lawn areas. |
| Mixed / tall growth | DependsTall fescue, St. Augustine, and overseeded lawns require more frequent blade swaps (every 3-4 weeks vs. 6-8 weeks). Motor load increases. | DependsNo test of the i2 LiDAR Pro in long or overgrown grass was found. |
| Thick (Bermuda / Zoysia) | DependsDense or thick turf (Bermuda overseeded, dormant thatch) can clog discharge and strain motor. May benefit from rougher blade angle adjustment. | DependsNo test in thick or dense turf was found for its 22 cm six-blade disc. |
| Boundary setup | ||
| Wireless required | Good405XE NERA is wireless-first; EPOS virtual boundary is the primary use case. No wire-setup friction. | GoodIt maps and navigates with LiDAR, network RTK and vision, with no wire or antenna. |
| Wire required | Poor405XE NERA does not support perimeter-wire operation. Owner wanting traditional wire boundary should choose wire-based Automower models. | PoorSegway sells it as wire-free only, with no boundary wire installation option listed. |
| No preference | GoodNo boundary preference? 405XE NERA's wire-free design eliminates installation work and ongoing wire maintenance. | GoodIts wire-free setup meets a buyer with no boundary preference. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
What the score is built from.
Nine inputs across three pillars, each weighted as shown and each scored so more is better. A robot can lead on one and trail on another, which is the point of showing them apart.

What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Husqvarna Automower 405XE NERA
Wire-free setup sounds low-friction, but EPOS requires line-of-sight satellite visibility to maintain the virtual boundary. Dense tree cover, metal structures, and weather patterns affect reliability in ways traditional perimeter wire does not.
Seasonal blade maintenance remains mandatory every 4-8 weeks of active mowing (spring through fall). No self-sharpening; dull blades harm grass health and increase motor load.
Segway Navimow i2 LiDAR Pro
LiDAR navigation keeps it on course under trees without an antenna, but there is no edge deck and about 20 cm of border stays uncut.
Quiet in use, below 55 dB in Notebookcheck’s measurement, yet about 13 W on standby lifts its monthly energy use.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Husqvarna Automower 405XE NERA
- Properties with steep slopes or dense boundary vegetation
- Husqvarna publishes two slope figures for this model: 30 percent maximum inside the installation and 20 percent maximum at the boundary. Those are gradients, not degrees, so 30 percent is about 16.7 degrees and 20 percent is about 11.3 degrees. The boundary figure is lower because turning at the edge is where traction is lost, and it governs where the wire or the virtual boundary can be routed on sloping ground. Heavy tree canopy also degrades satellite reception where EPOS is used.
- Buyers expecting virtual boundaries at the base price
- Husqvarna lists the 405XE NERA and the 405XE NERA with wire free technology as separate products, the wire-free version costing roughly 400 pounds more, and a NERA machine also needs the EPOS Plug-in module fitted to the back of the mower. Buying the base configuration and expecting an app-drawn perimeter means a boundary wire installation instead.
- Yards with persistent WiFi-free zones or GPS dead zones
- EPOS requires consistent satellite visibility. Signal loss forces return to charging station; unreliable coverage makes autonomous operation unpredictable.
- Budget-conscious buyers seeking lowest-cost robotic mower
- $2,400 MSRP reflects wire-free premium. Entry-level wire-guided Automowers and alternatives exist at substantially lower price points.
Segway Navimow i2 LiDAR Pro
- Owners who want crisp lawn edges
- Notebookcheck found an unmowed border of around 20 cm where there is no ground-level transition, and no edge-cutting deck.
- Owners focused on energy use
- Notebookcheck measured about 13 W on standby and nearly 12 kWh a month for a 500 m² lawn mowed three times a week.
- Lawns larger than 2,000 m²
- Segway rates the i220 LiDAR Pro for 2,000 m² and the i210 for 1,000 m².
- Lawns scattered with small balls
- Notebookcheck saw a neon-yellow tennis ball usually run over or touched, though larger objects were avoided.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Husqvarna Automower 405XE NERA
- Weekly: Check the blades for dents and dulling; clear cut grass from the deck and around the blade discs. The Automower mulches, so there is no discharge chute or collector to empty.
- Every 4-8 weeks during the mowing season: Replace the blades along with their screws. Husqvarna states Automower blades are single-use and must never be sharpened, because sharpening weakens the blade’s safety coating and can lead to blade breakage. The mower carries two discs of three blades; Husqvarna Classic blades sell in packs of 9 or 45, from about £21 for the 9-pack with screws included.
- Monthly: Inspect and clean charging-station contacts to prevent corrosion.
- Seasonally: Charge the battery fully, clean the machine, and store it indoors above freezing over winter.
- Annually: Apply firmware updates as released and verify the boundary installation before the first run of the season.
Segway Navimow i2 LiDAR Pro
- Weekly: Trim the roughly 20 cm border the mower leaves along raised lawn edges, per Notebookcheck.
- As needed: Clear tennis balls and small toys before mowing.
- As needed: Replace the blades on the six-blade disc; six spares come in the box.
- As needed: Edit mowing areas and restricted zones in the Navimow app map editor.
- Annually: Renew 4G data at 29.99 euros a year after the first free year if remote control is wanted.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
| Robot | Evidence status | Sources reviewed | Last assessed |

| Segway Navimow i2 LiDAR Pro | Provisional | 4 | Sep 2026 |
Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
