01 Classification

What each one does on its own.

The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.

V
Generalized
Any task, any setting
IV
Environmental
Handles new obstacles without help
III
Conditional
Finishes familiar jobs on its own
II
Assisted
Runs preset routines, needs rescue
I
Manual
One action, on command

02 Assessment

Where they actually differ.

The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

03 Measured against the class

How far apart is a long way?

A number only means something next to the spread it sits in. Each track below is the real range across every classified robot in the class, with the median marked.

04 Ownership

What the numbers leave out.

The trade-off

What each design gives up to be good at what it is good at.

Grillbot

The physical scrubbing motion is fully automated. The judgment of whether the grate is clean enough is not.

Offline operation means no connectivity risk and zero app dependency; it also means no firmware path to address the brush wear and battery degradation patterns that owner forums have documented for over a decade.

Moflin

Processing audio on-device limits cloud dependency, but also limits Moflin to reacting to tone and touch rather than understanding spoken words.

Having no camera reduces its data-privacy footprint, but also means it cannot recognize faces or navigate.

Who each one is wrong for

Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.

Grillbot
Owners expecting sensor-driven cleaning judgment
Unit runs its cycle regardless of grate condition. It does not extend for heavy buildup or stop early when clean. Gating decisions remain entirely with the owner.
Heavily corrugated or irregular grate surfaces
Bounce-pattern navigation produces non-deterministic coverage. Owner reports document missed corners and low-contact zones on heavily textured or charcoal grates.
Owners expecting battery service years down the line
The unit runs on a rechargeable 7.4 V lithium-ion pack. Capacity falls with cycles and age as lithium packs do, and while Grillbot sells replacement packs, availability for an older unit depends on stock at the time.
Heavy charcoal or encrusted grate cleaning
Owner reports cite inconsistent coverage on high-heat charcoal residue and irregular charcoal geometry. Heavy buildup is a documented limitation.
Moflin
Buyers wanting a mobile or task-performing robot
Moflin has no wheels or legs and performs no household task; it does not move from where it is placed.
Households wanting voice-command or conversational features
Moflin reacts to voice tone, not spoken commands or conversation; it has no chatbot or assistant function.
Anyone needing more than about 5 hours between charges
Battery life is limited to approximately 5 hours of active use per the manufacturer.

What stays your job

The upkeep ownership hands back to you, whatever the autonomy level says.

Grillbot
  • After every use: Rinse unit and brush heads to remove residue; allow to dry before storage.
  • By inspection: Replace brush heads when wires are flattened, splayed or missing. Grillbot publishes no cycle interval, so wear is judged by looking at the heads. Brass for standard gas; stainless for heavy buildup.
  • Before seasonal storage: Store the lithium pack partially charged in a cool, dry place and top it up occasionally over the off-season. Do not deep-discharge it before storage.
  • Annually: Inspect drive wheels and brush motor housing for debris or grease accumulation.
  • As needed: Replace the battery when it no longer completes a cycle; parts availability depends on manufacturer stock.
Moflin
  • Daily: Return Moflin to its charging base; it cannot reach the base itself, and a charge delivers approximately 5 hours of active use with an approximately 3.5 hour recharge, per Casio.
  • As needed: Wipe soiled fur with a cloth moistened with water or mild detergent and wrung out, per Casio’s care instructions; never wash it, splash it, or launder the fur.
  • As needed: Contact Casio support if the fur loses its softness or becomes heavily soiled; the fur is not owner-removable.
  • As needed: Apply updates through the MofLife companion app over Bluetooth.
  • As needed: Keep it within Casio’s stated operating range, 5-35 degrees C and 20-80 percent humidity, non-condensing.
05 Evidence

How much each of these is standing on.

Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
