Segway Navimow i105N

Name: Segway Navimow i105N
Brand: Segway

Wire-free by design: Segway's EFLS fuses RTK positioning with an onboard AI camera so the i105N maps its yard without a buried boundary wire, at the small end of Segway's mower lineup.

Autonomy Ladder

Why Level III.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyCopes with everyday clutter and frees itself, shown by independent testing.
To reach Level IVIndependent testing shows it avoids ordinary obstacles before contact, copes without the space being cleared, and frees itself when stuck.
IIIConditional AutonomyThis robot

Segway Navimow i105N finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control

RTK-GNSS positioning fused with an onboard AI camera for obstacle detection (Segway EFLS 2.0 with Visual SLAM mapping); wire-free boundary set through an app-guided mapping walk, no buried perimeter wire.
Why this level
- Segway documents EFLS, RTK positioning fused with an onboard AI camera, driving unattended mowing runs after an app-guided boundary setup.
- Camera-based recognition targets common yard objects, but published siting guidance also flags dependence on a clear satellite view, a documented constraint keeping this Level III classification below full autonomous obstacle handling.

CapableAt or above 39% of the 432 robots we scoreand 22% of the 109 scored robot lawn mowers

DeficientLimitedCapableStrongExemplary

Measured on 8 of the 9 inputs16% not counted

Our assessment did not establish an independent source for field failure rate on this machine, so that input is left out of the score rather than guessed at, and the rest re-weighted to fill the space. A gap in what we have been able to verify is not evidence against the robot. Where a whole pillar has nothing measured, we publish no number at all.

Operating envelope50−0.7
Task completion68−0.6
Coverage and navigation65−0.5

Capability40% of the score61What it does without you.

Task completion16% of the score68

Evidence

Segway documents EFLS-guided mowing completing a mapped yard on a set schedule without a human closing each session; independent, model-specific completion-rate reporting was not found for the i105N specifically.

Coverage and navigation10% of the score65

Evidence

The Navimow app builds and retains a lawn map from the initial AI-camera and RTK-guided walk, per Segway's own setup documentation; whether coverage is retained through terrain changes without a manual reset was not independently confirmed for this SKU.

Edge-case recovery10% of the score52

Evidence

Segway's support documentation describes the mower halting and alerting the app when it loses its position fix or becomes stuck, rather than resuming unattended; no independent report of self-recovery from these states was found for the i105N.

Operating envelope4% of the score50

Evidence

Segway's RTK positioning is documented to require a reasonably open view of the sky; the company's own siting guidance flags dense tree cover and tall nearby structures as conditions that degrade accuracy.

Dependability40% of the score65Whether it keeps doing it.

Field failure ratenot countedno source verified33

Evidence

No independent field-failure reporting specific to the i105N was found. 33 is the unevidenced-anchor placeholder value, not a measured figure; the input is listed in v4_unevidenced_inputs so the engine excludes it from the composite rather than counting it at full weight.

Software stability14% of the score65

Evidence

The mower updates through the Navimow app's connected firmware channel; no independent report of an update regression was found for this line.

Support longevity10% of the score65

Evidence

Segway sells replacement blades and accessories through its own store and standard retail channels and has maintained the Navimow i- and H-series lines across multiple hardware generations since introduction.

Ownership burden20% of the score72What it asks of you.

Routine maintenance12% of the score70

Evidence

Maintenance is limited to periodic blade swaps, clearing grass buildup from the underside, and wiping the obstacle-detection camera, per Segway's published care guidance; there is no dustbin, mop pad, or dock reservoir to manage.

Consumables8% of the score75

Evidence

The only routine consumable is the pivoting blade set, priced by Segway and third-party retailers as a low-cost accessory replaced on a seasonal cadence (priced by the consumables engine).

Five-year costNot costed

Priced within Segway's entry i-series tier; exact five-year cost is not established for this record.

Data postureCloud-linked

Account required. Maps and telemetry leave the home; core function survives an outage.

What leaves the homeDocumented

The onboard camera processes imagery locally for real-time obstacle detection during mowing. A Navimow account is required to set up the mower, and lawn map geometry, mowing schedule and diagnostic data sync to Segway's cloud through the app. Segway has not published a detailed breakdown of what, if any, raw camera footage is retained or transmitted.

OWNERSHIP

Living with it.

A newer wire-free platform; RTK sky-view dependency is the recurring documented constraint.

Segway's own siting guidance names dense tree cover and tall structures as conditions that degrade RTK accuracy. Independent long-term field data specific to the i105N is limited.

Reliability trendUnprovenowner-reported arc

What goes wrong · not yet documented independently

The independent record is still forming. Failure modes are listed once an outside source reports them.

Upkeep routine

Monthly12×/yr

Wipe down the AI camera lens on the mower body to keep obstacle detection accurate. · Check the underside for grass buildup and clear it away from the blade disc and wheels.

Seasonal4×/yr

Replace the pivoting cutting blades; more often on thick or fast-growing turf. · Clean the charging contacts on the dock and mower before spring startup. · Store the mower and RTK reference station indoors over winter per Segway's cold-weather guidance.

Yearly1×/yr

Check wheel motors and drive belts for wear before the new mowing season.

As neededno fixed schedule

Reposition or re-survey the RTK reference station if satellite accuracy drifts.

Safety notes

CautionSpinning blade beneath deck: Blades stop within seconds of a lift or tilt event, but the underside carries no continuous physical guard.

NotePets and children nearby: Camera-based obstacle avoidance is not guaranteed; supervise pets and young children during scheduled mows.

NoteRTK reference station power supply: The base station needs a permanent outdoor-rated power connection, which constrains where it can be sited.

Common questions

What people actually ask.

5 answered

OperationDoes the Navimow i105N need a buried boundary wire like older robotic mowers?

No. It uses Segway’s EFLS system, RTK positioning fused with an onboard AI camera, to map and hold its mowing area without any wire in the ground.

OperationCan the i105N mow a yard with a lot of tree cover?

RTK positioning needs a reasonably clear view of the sky, so heavy canopy or nearby tall structures are a documented constraint on wire-free RTK mowers generally, not a condition Segway advertises around.

OperationHow much yard can the i105N actually cover?

It sits at the small end of Segway’s i-series lineup; owners with larger or more complex lots are pointed toward higher-tier i-series models or the AWD H-series.

OperationDoes the i105N's AI camera stop it from hitting garden hoses or small toys?

Camera-based obstacle detection is documented to recognize common yard objects, though thin or low-profile items like hoses and stakes are a harder case for any vision-based mower to catch reliably.

CompatibilityIs there a subscription fee to use the i105N's app or RTK positioning?

Segway has not published a required ongoing subscription for the i105N’s core mowing and app functions.
