STIGA shipped a STIGA.GO update in July 2025 for its A-series robot mowers, including the A 1500.

Full assessment

AutonomyLIII capabilities expanded

ReadinessReady Now strengthened

ScoreScores unchanged

Owners gained automatic overnight firmware installs, perimeter points adjustable by 5, 10 or 20 centimeters, on-demand border cuts per zone, and a signal checker reading antenna coverage during setup.

WatchingWhether the checker reduces installation-stage RTK dropout reports.

Impact on autonomy

Automatic overnight updates install new firmware during scheduled charging without owner action.
Owners can nudge individual perimeter points by 5, 10 or 20 centimeters in the app.
Force border cut lets an owner trigger a perimeter pass on one zone on demand.

Impact on readiness

A signal checker shows live antenna coverage while positioning the charging dock.
Automatic firmware installs remove a manual update step owners previously had to trigger themselves.
Force border cut runs an unscheduled perimeter pass on a single chosen zone.

Claim check4 claims reviewed

STIGA calls the July 2025 rollout completely free and easy to install

The update ships as an in-app STIGA.GO download; owners still need a compatible app version and network connection to receive it

Automatic Robot Update is presented as hands-off maintenance

STIGA's own description limits automatic installs to scheduled nighttime charging sessions, not an always-on background process

The signal checker is marketed as solving connectivity issues during installation

STIGA describes it as real-time coverage feedback while driving the mower manually; it reports signal strength rather than resolving weak-signal spots itself

Perimeter editing is billed as new flexibility for boundary management

The feature adjusts existing mapped points in fixed 5, 10 or 20 centimeter steps rather than allowing free-form redrawing of the RTK perimeter

Bottom lineThe July 2025 update reduced manual maintenance steps and added diagnostic tools for the A 1500's existing RTK setup, without changing how the mower defines its cutting boundary.

Update Scope: STIGA’s own magazine describes a STIGA.GO app update rolled out in July 2025 for its A-series robot mowers, a lineup that includes the A 1500. Community changelog discussion on Roboter-Forum.com’s Stiga A-series board tracked the same round of app changes.
New Features: Automatic Robot Update lets owners opt into installing new firmware automatically during a scheduled nighttime charging session rather than triggering it manually. A perimeter editing tool lets owners move existing boundary points in 5, 10 or 20 centimeter increments directly in the app. Force Border Cut runs an unscheduled perimeter pass on a single selected zone without waiting for the next scheduled cut. A Signal Checker gives real-time antenna coverage feedback as the mower is driven around the garden, intended to help owners choose a docking station location with adequate signal.
What Did Not Change: The update operates on the RTK-based virtual perimeter the A 1500 already uses; it edits existing mapped points and reports on signal quality rather than changing the underlying reference-station navigation method.

UpdateSoftwareMajor advance

STIGA A 1500 gains zone priorities and obstacle alerts in April 2024 app update

STIGA released a firmware and app update across its A-series robot mowers, including the A 1500, in April 2024.

Full assessment

AutonomyLIII capabilities expanded

ReadinessReady Now strengthened

ScoreScores unchanged

The update added zone priority ordering, temporary stay-away areas, and notifications when the mower registers repeated obstacle hits, all set through the STIGA.GO app rather than the RTK reference station.

WatchingWhether the added notifications cut down on unreported obstacle strikes over a full mowing season.

Impact on autonomy

Obstacle notifications flag three or more consecutive close hits per mowing session for review.
Zone priority ordering lets owners set which of several mapped zones the mower cuts first.
A temporary stay-away setting excludes a selected area for an owner-chosen period without remapping.

Impact on readiness

Zone deactivation lets owners pause a single mapped zone without altering its RTK boundary data.
The obstacle log gives owners three responses: remove, register or continue monitoring the item.
The long exit function reverses the mower two meters before it resumes its cutting route.

Claim check4 claims reviewed

STIGA frames the April 2024 update as new zone control flexibility for its robot mowers

The changes are software-side scheduling and notification features; the physical RTK antenna and reference-station setup that define the mowing zones did not change

The obstacle notification is marketed as detecting hazards for the owner

STIGA's own description triggers the alert only after three consecutive close hits in one session, then surfaces it as a post-session summary rather than a real-time warning

STIGA presents the update as a single April 2024 release

STIGA's own update page describes feature availability tied to app version rather than a single simultaneous firmware push to every A-series unit

Zone priority and stay-away settings are billed as new scheduling flexibility

Both features operate inside zones the owner already mapped with the RTK reference station at installation; neither changes how the boundary itself is set

Bottom lineThe April 2024 update refined how owners schedule and monitor zones already mapped by the A 1500's RTK reference station, without changing the underlying navigation hardware.

Technical notes3 sections

Update Scope: STIGA published its “Autonomous Robot New Firmware” bulletin on April 18, 2024, describing a STIGA.GO app and firmware update for its A-series robot mowers, including the A 1500. STIGA’s companion “April” feature page on its own magazine lists the A 1500 among the models that received the update.
New Features: The update added zone priorities, letting owners reorder which mapped zone the mower cuts first from inside the app. A stay-away setting excludes a selected area between two points for an owner-set duration. Obstacle notification logs sessions with three or more consecutive close hits and lets owners mark each detected object as removed, registered, or under continued monitoring. A long exit function reverses the mower roughly two meters before resuming its route, and a zone deactivation toggle pauses a single mapped zone.
What Did Not Change: The update is software-side. The A 1500’s RTK reference station and the virtual perimeter it establishes were not altered; the new controls operate on zones the owner had already mapped at installation.

NewsAutonomySetback

A 1500 RTK signal loss reports surface across EU owner communities

Owner reports collected across EU lawn-care forums in mid-to-late 2023 documented recurring RTK signal loss on the A 1500 in gardens with significant tree cover or narrow sky view, triggering safety pauses and requiring manual restarts.

Full assessment

AutonomyL3 capabilities reduced

ReadinessPromising progress weakened

ScoreReliability -5

Stiga updated support guidance to flag minimum sky-view requirements for reliable RTK fix.

WatchingWhether a firmware-level fallback behavior or multi-constellation receiver revision addresses the underlying sensitivity gap.

Impact on autonomy

RTK fix loss under tree canopy causes mid-cycle halts, requiring owner intervention
Automatic perimeter re-learning required after extended signal-loss events in some owner reports
Satellite positioning documented as unreliable below approximately 50% open sky view

Impact on readiness

Gardens with mature tree canopy classified as marginal installation environments by support docs
Owner setup guidance updated to include sky-view assessment before purchase commitment
Repeat manual restart burden raises effective supervision requirement above stated spec

Claim check4 claims reviewed

Wire-free setup via RTK satellite positioning

Owner reports document signal loss under tree canopy; wire-free operation is environment-dependent, not universal

2-5 cm positioning accuracy

Accuracy documented at specification under open-sky conditions; performance degrades in low-sky-view gardens per support documentation

Autonomous systematic cutting pattern

Pattern execution interrupted by safety pauses when RTK fix is lost; owner reports describe multiple mid-cycle halts per session in affected gardens

Suitable for gardens up to 2,000 sqm

Area coverage is accurate for open-sky installations; tree-heavy gardens of the same area show materially lower reliability per owner community data

Bottom lineThe wire-free premise holds in gardens with clear sky exposure; the A 1500's RTK reliability drops measurably in the shaded suburban gardens it is frequently marketed toward.

Technical notes3 sections

RTK Signal Behavior: The A 1500 uses a single-band RTK GNSS receiver for positioning. Owner-reported failures concentrated in gardens with conifer or deciduous canopy covering more than roughly half the operating area, conditions where multipath interference and reduced satellite count degrade RTK fix quality. Signal loss triggers an automatic safety stop; the mower does not fall back to a degraded GPS-only mode.
Support Documentation Response: Stiga’s EU support materials were updated to include a sky-view assessment step in the pre-purchase checklist, advising a minimum unobstructed sky angle for reliable RTK convergence. No hardware revision or firmware-level fallback mode was announced in response to this pattern during the 2023 reporting window.
Owner Community Scope: Reports appeared across German, Swedish, and French lawn-care forums and the Stiga community support portal. The pattern was consistent enough that multiple independent threads reached the same diagnostic: sky-view obstruction rather than unit defect. Stiga support responses on individual tickets acknowledged the limitation without offering a unit-level fix.
