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

Stiga A 1500 finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control

RTK satellite positioning with app-defined virtual boundaries and autonomous systematic cutting pattern
Why this level
- RTK satellite positioning with app-defined virtual boundaries and a systematic cutting pattern qualifies as Level III, Conditional Autonomy.
- The robot navigates the mapped property to centimeter-level accuracy against a reference station supplied in the box, without a physical wire perimeter.
- Smartphone setup and monitoring are required, but once configured the robot executes multi-session mowing autonomously across as many as 10 zones.
- Accuracy is conditional on satellite visibility rather than on any external service.

Capability40% of the score63What it does without you.

Task completion16% of the score72

Evidence

Testberichte.de's graded verdict (1.4, 14.03.2023) lists as strengths that it "maeht zuverlaessig und auch hohes Gras" (mows reliably, including tall grass), a good ratio of working to charging time (150 minutes of work to 120 minutes of charge), and "nur selten Stoerungen" (only rare faults). The same verdict lists as a weakness "breite Randstreifen bleiben stehen": wide perimeter strips are left standing, so a human finishes the edges after it.

Coverage and navigation10% of the score70

Evidence

Testberichte.de describes AGS satellite guidance that schedules work for when the GPS signal in the garden is strong, and four selectable systematic cutting patterns (north-south, east-west, checkerboard and dense grid), so coverage is planned rather than random. The recorded miss is consistent and structural rather than occasional: wide uncut edge strips remain after every pass.

Edge-case recovery10% of the score48

Evidence

Gardens Illustrated, after six weeks of testing, found the mower does not extract itself: "If you leave things in its way it will try to go around them, but it's likely to get stuck," and "this mower isn't going to be able to make its way in the world all on its own." The same test records one occasion when "the mower inexplicably stopped working and I had to cont[act]" the supplier, so the resume step is human either way.

Operating envelope4% of the score50

Evidence

Gardens Illustrated names the constraint plainly: "In an ideal situation it would be in a garden that is fairly uniform in shape." It "did the job of mowing my central lawn (64 m2) very well, but the mower would have found the section of my lawn with apple and pear trees in it too confusing," so a treed or subdivided garden falls outside what it handles.

Dependability40% of the score70Whether it keeps doing it.

Field failure rate16% of the score64

Evidence

Four seasons since the April 2022 EU launch, so no cap applies, with no recall and no documented failure mode of any kind on file. The constraint is that there is almost no evidence in either direction: the record carries no owner-report source at all, its two press items are unlinked and marked ongoing, its three manufacturer documents are unlinked, and product_status is provisional. Absence of a failure record is absence of evidence, not a clean record.

Software stability14% of the score82

Evidence

The machine is 4G-connected with cloud-held boundaries and scheduling and Stiga bundles connectivity for the robot's lifetime, so an update channel exists and is in constant use. No regression is reported, and the record carries no firmware source of any kind: no changelog, no release history, no independent account of what any update changed. Essentially the ordinary silent-record case, marked just below it because the record documents a standing service dependency that disables operation during outages, which is a live software-side exposure rather than a settled one.

Support longevity10% of the score63

Evidence

One genuinely unusual commitment sits on this record and it is vendor-established, which is what this input scores: Stiga states its autonomous mowers come with free connectivity for the lifetime of the robot at no extra cost, so the 4G link the machine depends on carries no renewal cliff. The reference station ships in the box rather than being a separate purchase, and approved replacement blades are available. Against it, distribution is EU-focused with very limited North American availability, and the record warns of import restrictions, warranty voids and support gaps outside Europe.

Ownership burden20% of the score62What it asks of you.

Routine maintenance12% of the score46

Evidence

Wire-free is not chore-free here, and three of the six recurring items are on the positioning system rather than the deck: weekly verification that the app boundary map still matches the physical yard, a monthly confirmation that the reference station is powered and securely mounted, a seasonal recalibration with a full perimeter re-walk, and an annual inspection of the station mount, cabling and power supply. Around those sit weekly deck clearing, blades every four to six weeks and a monthly dock contact wipe. The weekly map check is the heaviest single item in the wire-free tier.

Consumables8% of the score86

Evidence

Blades are the only consumable, Stiga-approved and replaced as cutting quality declines rather than sharpened, and there is nothing else recurring at all: no wire, no splices, no filter, no reference station to rent, and the record is explicit that there is no correction subscription to buy or renew because the station is your own. Held below the top by the four to six week blade interval, which is on the short side for the set, and by the absence of any published set price.

Five-year cost$2,210

Middle for robot mowers, and the purchase figure is the record's own estimate rather than a list price. About 1,630 dollars converting the middle of the 1,200 to 1,800 euro range the record marks as estimated, plus roughly 400 dollars of blade sets over five years at the four to six week interval and one replacement battery pack. Nothing else: the RTK reference station ships in the box, there is no correction subscription, and Stiga includes the 4G connectivity for the lifetime of the robot at no extra cost.

OWNERSHIP

Living with it.

Satellite navigation is novel for consumer mowers; GNSS signal loss and regional service gaps are documented friction points. RTK accuracy depends on infrastructure, not product design.

Launched in 2022; ownership and reliability data remain thin. EU early-adopter forums report successful deployments where GNSS correction is robust; signal loss in areas with tree cover or building shadow causes navigation drift. No major recalls or design defects documented yet.

Yearly1×/yr

Inspect the reference station mount, cabling and power supply before the season starts; check drive wheels and the blade disc for wear.

Safety notes

CautionSpinning blade during scheduled autonomous operation: Mowing occurs on programmed schedule without human presence. Blade contact risk for pets or objects in the yard.

NoteRTK signal loss disables position verification: Unlike wire-guided systems with a hard boundary, RTK signal loss allows the robot to drift; boundary violation is possible during service interruptions.

Common questions

What people actually ask.

5 answered

OperationDoes the Stiga A 1500 require a perimeter wire, or does it use GPS for boundaries?

It uses RTK (Real-Time Kinematic) satellite positioning for wire-free boundary definition. Virtual boundaries are set via smartphone app by walking the property perimeter. No physical wire installation is required, but RTK correction service availability is critical to accuracy.

OperationDoes the A 1500 need a GNSS correction service subscription?

No. The reference station that supplies the corrections ships in the box and is part of the required setup, so the correction source is your own station rather than a regional network. Stiga states that its autonomous mowers come with free connectivity for the lifetime of the robot at no extra cost; the link between mower, station and cloud is 4G. There is no correction subscription to buy or renew.

OperationHow accurate is the RTK positioning, and can it get lost like a wire-guided mower?

RTK positioning is typically accurate to within 2-5 cm with a clear satellite view and the reference station in range. Heavy tree cover, roof overhang or building shadow degrade the fix, and the mower cannot hold its mapped boundary without one. There is no buried wire acting as a physical backstop, so any area that never gets a reliable fix is an area the machine will not cut.

OperationWhat is the maximum yard size the Stiga A 1500 covers, and how many charge cycles does a full lot require?

Stiga rates it at up to 2,500 m² (about 0.62 acre) across as many as 10 cutting zones. Runtime is 150 minutes per charge with a 120 minute recharge, so a full-size lot is covered over several sessions depending on grass density and the programmed pattern. Systematic mowing rather than a random pattern reduces total coverage time.

OwnershipIs the Stiga A 1500 available in North America, and what is the warranty coverage?

North American availability is very limited; distribution is primarily EU-based. North American customers may face import restrictions, warranty voids, and support gaps. Verify availability with regional Stiga distributors or authorized dealers before purchase.
