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

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.

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.

Kyvol Cybovac S31 Smart Laser Robot Vacuum

A self-emptying base reduces dust-bin handling to roughly every 60 days, but the mop still relies on a manually filled and emptied external water tank rather than a self-washing station.

The original design and price point were competitive for its class, but that original value is now weighed against a sold-out official US store and signs of a neglected product catalog.

Vision recognition solves false-positive detection but does not shrink the operational scope, mapping and return-to-dock remain bound by dock placement and single-floor assumption.

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.

Kyvol Cybovac S31 Smart Laser Robot Vacuum
Buyers wanting a currently purchasable new unit
As of this research, every model on Kyvol's official US store, including the S31, is listed as sold out.
Buyers who need confidence in ongoing parts or software support
The wider Kyvol catalog shows broken product pages and pricing inconsistencies consistent with reduced vendor upkeep.
Buyers wanting a self-washing mop system
The S31 mops from a manually filled external water tank rather than a self-cleaning pad station.
Trifo Lucy Ultra
Homes with high-pile or shag carpet
Owner reports document suction loss and inadequate agitation on plush flooring. Navigation quality does not overcome brush-to-surface contact limits on thick pile, and no automatic mop lift is documented, so the water tray comes off before running on carpet.
Households that will not put a networked camera on a moving robot
The camera is the product's headline feature and is not removable. Review testing found no cloud storage of stills or video, but the robot still carries a 1080p sensor with night vision through every room it maps.
Owners requiring true hands-off operation
There is no auto-empty base. The 252 ml bin is emptied and rinsed by hand, the 366 ml tank is refilled for each mopping pass, and filter and brush upkeep sits with the owner.
Commercial or industrial-scale deployments
Consumer-class hardware and software; not rated for continuous multi-unit operation. Designed for residential 1-2x weekly schedules.

What stays your job

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

Kyvol Cybovac S31 Smart Laser Robot Vacuum
  • After every use: Empty, rinse, and air-dry the external mop water tank and remove the cloth after mopping runs; the S31 has no self-washing pad system.
  • Weekly: Cut wrapped hair from the main brush and side brush and wipe the LDS laser turret and cliff sensors.
  • Monthly: Check the base station’s dust bag; Kyvol rates the base for up to 60 days of debris, so expect a change roughly every two months.
  • As needed: Replace the filter, brushes, and mop cloths when worn; Kyvol publishes no replacement intervals for the S31.
  • As needed: Stock spare bags and filters while aftermarket listings last; Kyvol’s US store lists every model sold out, and third-party channels show refurbished units and parts rather than new stock.
  • As needed: Update no-go zones and cleaning schedules in the Kyvol app.
Trifo Lucy Ultra
  • After most runs: Empty and rinse the 252 ml dustbin; rinse the mop pad and empty any water left in the 366 ml tank.
  • Weekly: Tap the filter clean; wipe the camera lens with a dry cloth.
  • Every 3-6 months: Replace or clean the primary filter (~$12-18); inspect the side brush.
  • Quarterly: Rotate or replace the side brush (~$15-20); verify dock contact cleanliness.
  • Seasonally: Check charging contacts and dock alignment after heavy use periods.
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.
