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

Kress KR172 Mission RTKn finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control

RTKn satellite positioning with inertial navigation and odometry fallback under weak signal. The US KR172 is listed without the OAS obstacle avoidance system.
Why this level
- RTKn positioning holds centimeter-level accuracy inside Kress's network coverage, and inertial navigation and odometry carry the run when the signal weakens under shade.
- The US KR172 is listed without the OAS obstacle avoidance system, so obstacles are handled by contact and loose items have to be cleared first, which rules out Level IV.

Our assessment did not establish an independent source for edge-case recovery, field failure rate on this machine, so those inputs are 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.

Capability40% of the score78What it does without you.

Task completion16% of the score75

Evidence

Mowing Magic's tested review of the Kress RTKn line (the KR172's platform; the page covers the line rather than naming the SKU) reports it "mows in straight parallel lines" and "remembers exactly the line it left off on and continues back on that same line", with floating cutting heads giving "a near-perfect cut regardless of the terrain or undulations". Held at 75 because the owner cannot close the loop alone when the yard changes: "for anything major, the installer will need to come out again" with a mapping cart.

Coverage and navigation10% of the score82

Evidence

Systematic paths inside a boundary walked once at setup and retained across the season, and the dead-reckoning fallback matters here for a reason that is not precision: when the correction signal weakens under shade the machine holds its routing on inertial navigation and odometry rather than abandoning the lane, so coverage survives conditions that halt other satellite mowers. Held below the systematic-and-retained anchor because a changed yard means walking the boundary again and no independent account of the in-boundary pattern exists on this record.

Edge-case recoverynot countedno source verified74

Evidence

It genuinely self-recovers from one of the two documented failure modes of the category: signal loss is bridged by inertial navigation and odometry and the schedule continues, which is the anchor's self-recovery clause rather than a halt. The other mode is unaddressed. With no OAS on the US variant, obstacle handling is contact-only, boggy ground and thick grass end in retrieval, and the only escalation path the record names for persistent positioning trouble is contacting Kress support.

Operating envelope4% of the score80

Evidence

Forty percent slope, up to 0.7 acre, and shade handled by dead reckoning instead of being a disqualifier, which is a broader envelope than EPOS or satellite guidance can claim on the canopy axis. Against it sits a constraint none of them have: the property must sit inside Kress's own RTKn correction footprint, and the record names a property with no network coverage as the case that rules the machine out entirely. Soft, boggy ground and dense annual grasses cost traction independent of positioning.

Dependability40% of the score74Whether it keeps doing it.

Field failure ratenot countedno source verified70

Evidence

Shipping since mid-2023, with no recall and no systemic defect reported. The record carries no failure modes section and lists press reviews and owner reports as source types with no links behind either, so there is no inspectable outcome evidence. No independent source reports on failures for this machine, so the input is left out of the score.

Software stability14% of the score82

Evidence

The machine carries a 4G modem and an app, so updates certainly ship, and no owner reports a regression pattern. Placed just below the ordinary-case anchor because this record carries no firmware or release-notes source of any kind, where other mower brands at least cite a support portal that publishes what-is-new notes. Absence of a changelog is not stability.

Support longevity10% of the score63

Evidence

A Positec brand with a published US MSRP, a dealer channel and blades sold in multipacks, which are commitments vendor material establishes, and no support term published in years. The specific risk that holds this down is structural rather than about parts: the correction signal comes from Kress's own network, so unlike a base station the owner possesses, the machine's core positioning ends if Kress stops operating that network or drops the region from its footprint.

Ownership burden20% of the score92What it asks of you.

Routine maintenance12% of the score87

Evidence

A light published schedule: monthly dock contact cleaning, blade inspection every three to six months, blade replacement every six to twelve, seasonal winterization and a spring app check. No boundary wire ever, so none of the weekly continuity chores the wired Automowers carry. The unlisted item is the pre-run lawn clearing the missing OAS forces, which I weighted lightly here since it is already scored in task completion.

Consumables8% of the score100

Evidence

Blades on a six to twelve month interval against four to eight weeks on the wired Automowers, sold in multipacks and replaced rather than sharpened, which is roughly $40 to $60 a year on a $2,500 machine. No wire, pegs or splice connectors. Kress's US materials disclose no separate fee for network access despite the correction signal coming from Kress infrastructure, which is an inexpensive positioning arrangement if it holds.

Reported, not scoredneither measures how well the robot works

Five-year cost$3,000

Middle of the range for wire-free robot mowers, with a low running cost. $2,499.99 at published US MSRP, roughly $250 of blades across five years on a six to twelve month interval, and one replacement battery pack. No boundary wire, no reference station and no antenna to buy, because the correction signal arrives over the machine's own 4G modem from Kress's network. The assumption a reader should see: this record contradicts itself on whether that network carries a fee, with the FAQ stating Kress's US materials disclose no separate charge while two other passages describe a subscription. The figure above assumes no fee, on the more specific statement; a subscription at typical category rates would add several hundred dollars across five years.

OWNERSHIP

Living with it.

Antenna network stability is the bottleneck; mower hardware and blade mechanics perform predictably in documented conditions.

Stableowner-reported arc

The record so far

RTK positioning reliability documented across 2+ years of European deployments; network availability and signal strength remain the limiting factor. No major firmware regression reported; blade wear accelerates in dense turf. Seasonal storage required in temperate climates.

What goes wrongnot yet documented independently

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

Questions

What people actually ask.

5 answered

OperationDo I need to bury a perimeter wire for the Kress KR172?

No. RTKn uses satellite positioning instead of boundary markers. You define the mowing area through the app; the mower respects virtual boundaries without physical installation.

OperationWhat if my property loses RTK signal temporarily?

The mower switches to inertial navigation and odometry and keeps working until a clear satellite connection is available again. Kress lists this dead reckoning as the mechanism for mowing under shade, so a canopy that interrupts the signal does not end the run. Sustained absence of network coverage, rather than a passing gap, is what stops autonomous operation.

CompatibilityDoes the KR172 need a base station, an antenna or a network subscription?

No. Kress delivers the RTKn correction signal over its own network, which is why the machine ships without a customer-side antenna, beacon or base station, and Kress’s US materials disclose no separate fee for network access. The published US MSRP is $2,499.99. The mower carries a 4G modem for that connection and an anti-theft system with GPS tracking.

OperationCan the KR172 handle slopes and thick Bermuda grass?

Kress rates the machine to a 40 percent maximum slope. Thick grass and wet conditions reduce traction; standard turf fares better than dense annual grasses.

OwnershipWhat parts need seasonal maintenance on the KR172?

Blade replacement (6-12 months depending on use), charging station cleaning (monthly), and winterization in cold climates (perennial storage indoors or under cover).
