Stihl iMow 6 EVO

The 6 EVO is the size step above the 5 EVO, not a change of approach: same wire boundary, same mulching cut on free-swinging blades, same app. What the extra money buys is area, a 28 cm cutting width, and a slope rating that a factory kit lifts to 55 percent. Anyone hoping the EVO generation moved STIHL off the perimeter wire will not find it here.

Autonomy Ladder

Why Level II.

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 AutonomyHandles new obstacles and re-plans in real time; rare in consumer products.
IIIConditional AutonomyFinishes whole jobs in familiar spaces; struggles at the edges.
To reach Level IIIMost sessions finish without intervention. Rescue is occasional, not routine.
IIAssisted AutonomyThis robot

Stihl iMow 6 EVO runs preset routines on its own, and the owner is its recovery system.
Why this level
- The mower keeps a schedule, detects obstacles, and docks itself, but the perimeter is a wire a person buries, coverage is not systematic, and there is no persistent map.
- Obstacle sensing improves the execution inside a hand-defined boundary rather than removing the need for one.

Capable

DeficientLimitedCapableStrongExemplary

Measured on 8 of the 9 inputs14% not counted

Our assessment did not establish an independent source for software stability 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 it reaches 30% of the rubric we publish no number at all.

Capability40% of the score66What it does without you.

Task completion16% of the score76

Evidence

derStandard tested the machine and reports it handling fully automatic mowing of large private lawns, with three free-swinging blades in a disc-cut arrangement producing a clean cut pattern. testberichte.de and a comparison test at drohnen.de reach the same reading across the iMOW 5, 6 and 7. The lawn is finished without a human closing the loop in normal conditions, which is at the 75 state.

Coverage and navigation10% of the score70

Evidence

The machine navigates on a dual arrangement of GPS and a guide wire, which is a more conservative design than satellite-only and is not subject to the reception failures that dominate the wire-free category. No missed-area complaint appears in the German test coverage read here. Systematic and retained with occasional misses is the 75 state, placed just below it because no source read here reports a measured coverage figure.

Edge-case recovery10% of the score45

Evidence

German testers name a specific and repeatable stranding mode: the machine is heavy, and reviewers report that the smallest edges can quickly become an insurmountable obstacle for it. That is a documented condition in which it stops and has to be freed rather than recovering. It halts cleanly rather than damaging itself, which sits between the 25 and 50 states. Software problems reported for the iMOW 5 EVO are a different model and are not read across to this record.

Operating envelope4% of the score72

Evidence

Rated to 3,000 square metres and to slopes of 45%, extendable to 60% with the upgrade kit, and reviewers describe it as small and manoeuvrable enough for twisted gardens and tight spaces. That is a wide envelope by the category's standards, held back by the edge-climbing weakness documented above. Just below the 75 state.

Dependability40% of the score66Whether it keeps doing it.

Field failure rate16% of the score62

Evidence

On sale since September 2023, so the under-twelve-month cap does not apply. No failure pattern for this model appears in the German test coverage read here. The supply difficulty reviewers mention, at a price of 3,299 euros, is a distribution problem and not a reliability one, and the software faults reported for the iMOW 5 EVO belong to a different model. A normal field record with no job-stopping pattern established sits at the 70 state; this is placed below it because the evidence is review text rather than a field study, which the anchor caps at 65.

Software stabilitynot countedno source verified—

Evidence

The only software-fault reports found in this model line attach to the iMOW 5 EVO, which is a different machine, and reading them across would be exactly the sibling substitution this record has to avoid. Nothing independent describes the 6 EVO's update behaviour or any regression. The input carries no value and is excluded from the composite. This states what our assessment established, not that no such reporting exists.

Support longevity10% of the score72

Evidence

This input scores vendor-published terms as commitments. STIHL sells and services the iMOW through authorised dealers who take official STIHL training, offers dealer installation and ongoing service for the robotic line specifically, and releases genuine parts and service manuals to those dealers, with iMOW blades and accessories separately orderable and spare parts themselves carrying a one-year warranty. A servicing-dealer channel is a stronger guarantee of a long service life than a mail-in warranty, and is the reason this scores above the category. Recorded with its terms so a later revision can score conduct against them.

Ownership burden20% of the score69What it asks of you.

Routine maintenance12% of the score62

Evidence

Blade changes and keeping the deck clear are the routine, ordinary for a mower covering this area. The app handles cutting height and scheduling without the owner going to the machine.

Consumables8% of the score80

Evidence

Three pivoting blades are the recurring part, inexpensive against a 3,299 euro purchase price and on an interval measured in months. No bag, filter or fluid. A low ongoing cost.

Common questions

What people actually ask.

3 answered

OperationDoes the STIHL iMOW 6 EVO use a boundary wire?

Yes. The EVO range is wire-guided. Ultrasonic sensors and obstacle detection work inside that perimeter; they do not replace it.

OperationHow is the 6 EVO different from the 5 EVO?

Size. The 6 EVO is rated to a larger area with a wider cut. The boundary method, the mulching cut, and the MY iMOW app are shared across the range.

OperationHow steep a slope can it manage?

STIHL rates it to 45 percent as sold, and to 55 percent with the gradient kit fitted.
