Yarbo

Yarbo M20

Name: Yarbo M20
Brand: Yarbo

A smaller take on Yarbo's modular yard robot, built on tracks rather than wheels and rated for 70% slopes. Crowdfunding raised over $3.6 million, and backer deliveries slipped past their August target.

Autonomy Ladder

Why Level IV.

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.
To reach Level VWorks across task types and environments it was never configured for.
IVEnvironmental AutonomyThis robot

Yarbo M20 sees ordinary obstacles before contact, copes without the space being cleared, and frees itself when stuck.

Navigation and control

NetRTK positioning with AI vision cameras, no base station
Why this level
- Yarbo documents wire-free NetRTK positioning with no outdoor base station, AI vision cameras watching for obstacles, and auto-charging that resumes the job where it stopped across multi-hour runs.
- Backer units have not shipped, so the assessment rests on that documentation.

IIIConditional AutonomyFinishes whole jobs in familiar spaces; struggles at the edges.

Human Readiness

Pre-release.

One question: what does buying this robot today walk you into? The state is computed from the record, and recomputed daily.

Pre-releaseThis robot

Yarbo M20 has not shipped to consumers, and a readiness rating is a claim about buying today.

Until consumer shipping starts, the Pre-Release Assessment carries the evaluation; the readiness clock starts at general availability.

PromisingAt or above 90% of the 91 robots we assess before release

SpeculativeConceptPlausiblePromisingReady

The hatched tail is unreachable by construction. A projection does not publish as a full mark, because the evidence that settles it does not exist yet: whether the thing ships and works in ordinary use. Those 10 points are what shipping has to earn.

Held below its arithmetic76 → 75

Capped at 75: demo match has no source outside the maker, and the top band requires evidence that it does.

The reading

Plausible: a scaled-down version of the modular tracked platform Yarbo already sells, crowdfunded with prices and a delivery target. Deliveries have slipped once and the final unit is unobserved in use. Pending shipping evidence.

Still open

Whether Core and Mower bundles actually ship in September 2026
Cutting width and confirmed cutting height range
Whether the M20 or only the M20i carries LiDAR
Real runtime per charge against the 110-minute figure
Whether 70% slope handling holds on wet grass with the mower module
Retail price and channel after crowdfunding

Three signals the number rests onweighted, then capped76What can be judged before anyone owns one.

Track Record50% of the assessment68

What this asks

Has this maker shipped what it demoed before, on schedule, with the promised capability?

What it rests on

Yarbo's earlier Y series reached retail, with its mower sold through Amazon and Lowe's; the M series has already slipped its August delivery to mid-September 2026, per BackerGuardian.

Engineering50% of the assessment84

What this asks

Are the demonstrated capabilities achievable in shipping form, or do they need breakthroughs not in evidence?

What it rests on

A tracked Core with swappable modules is the same approach Yarbo already sells in the Y series, scaled down; the new pieces are the smaller chassis and a two-stage snow blower module.

Demo Matchleft outNot judged

What this asks

What has been shown to work, against what is claimed in marketing.

What it rests on

Yarbo's release says IFA visitors could try the final version, but Talk Android and other coverage describe no observed mowing or slope climbing.

30% of the assessment has no source outside the maker and is left out; the number rests on what remains.

This is a projection from pre-shipping signals, not a measurement. When the robot ships, the assessment is archived, a first Robovations Score is computed from the field record, and the change is logged on the tracker rather than appearing as a new number.

Common questions

What people actually ask.

5 answered

OperationWhen will the Yarbo M20 ship?

Kickstarter backers were promised August 2026. BackerGuardian reports Core and Mower bundles slipped to mid-September 2026, with snow blower bundles targeting mid-November.

OperationHow does the Yarbo M20 differ from the M20i?

News reports and Yarbo dealer Zippy Lawnz say the M20i adds 360-degree LiDAR to the M20’s NetRTK and AI vision; one reviewer lists LiDAR on the M20 too.

OperationDoes the Yarbo M20 need a boundary wire or RTK base station?

No. Yarbo describes wire-free NetRTK positioning with no outdoor base station.

OperationHow heavy is the Yarbo M20?

A hands-on review and news reports put the Core at about 88 lb (40 kg) alone, before a module is attached.

OwnershipWhat did the Yarbo M20 cost on Kickstarter?

Launch coverage reports $4,199 for the four-module set at early-bird pricing, against a planned retail price of $5,099.
