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

Roborock RockMow X120H LiDAR finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control

360-degree 3D LiDAR with dual-camera VSLAM and AI obstacle avoidance; no RTK base station
Why this level
- Roborock documents 360-degree 3D LiDAR mapping with dual-camera obstacle avoidance, automatic lawn mapping, multi-zone schedules and rain sensing that sends it back to its dock.
- No independent test of that autonomy was found, so it is classified Level III until testing documents unattended mowing.

Robovations Score

Why the score is withheld

Not scored

The Robovations Score is withheld on this record. It is not a low score, and it is not an oversight.

Why

Our assessment did not establish an independent source for 7 of the nine inputs: task completion, coverage and navigation, edge-case recovery, operating envelope, field failure rate, software stability, routine maintenance.

The full assessment note

That leaves nothing measured in its capability. A score missing a whole pillar would not describe the machine, so no number is published.

What would change it

An independent account of its task completion that we have verified.
An independent account of its coverage and navigation that we have verified.
An independent account of its edge-case recovery that we have verified.

An independent account of its routine maintenance that we have verified.

Reported, not scoredneither measures how well the robot works

Five-year costNot costed

$3,199 Amazon list price with three years of 4G included; blade cadence is unpublished, so no five-year figure is stated.

Data postureCloud-linked

Account required. Maps and telemetry leave the home; core function survives an outage.

What leaves the homeDocumented

It carries a 360-degree LiDAR and two cameras, is controlled through the Roborock app, and includes a 4G connection for tracking. Where maps and camera imagery are processed was not verified.

OperationIs the RockMow X120H LiDAR the same as the RockMow X1 LiDAR?

OperationDoes the RockMow X120H LiDAR need an RTK antenna?

No. Roborock says it maps and navigates with 360-degree 3D LiDAR and cameras, with no RTK base station or boundary wire.

OwnershipDoes the X120H LiDAR's 4G tracking cost extra?

Amazon’s listing says three years of 4G connectivity are included without subscription fees.

OperationHow low can the RockMow X120H LiDAR cut?

The Amazon listing and a news report give 1.6 to 3.5 inches. Another report wrote 0.75 to 4 inches, which Roborock’s listing does not support.
