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.

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.

Ecovacs Deebot X12 OmniCyclone

The station is bagless and rated at up to 48 days between empties: PureCyclone 2.0 separates debris into a 1.6 L chamber, so there is no bag to buy, and the chamber is emptied by hand rather than lifted out sealed.

The station does the mop work and asks for the floor space: heated washing and hot-air drying arrive with 3.5 L clean and 2.7 L dirty water tanks plus the 1.6 L dust chamber, all of it needing a permanent position against a wall.

ROIDMI EVA

The dock is designed to self-empty and self-wash mop pads, but an independent review found the design under-delivered on both counts in practice, before the manufacturer’s closure removed any path to a fix.

Remaining retail inventory can still be found through some third-party channels, but buying it now means buying a robot with no manufacturer support of any kind.

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.

Ecovacs Deebot X12 OmniCyclone
Households not comfortable with a camera on the robot
Navigation pairs LiDAR with the AIVI 3D camera for obstacle recognition, and the AI features depend on Ecovacs' cloud services. A LiDAR-only robot maps the same floor without the camera.
Small or rental homes needing a portable dock
The OmniCyclone station is larger than a plain charging base: a 1.6 L dust chamber, 3.5 L clean and 2.7 L dirty water tanks, and a permanent position on the floor near an outlet. Homes that need the base moved or stored will find it awkward.
Carpet-only homes
The OZMO ROLLER 3.0 lifts 0.59 inches on carpet detection and a cover blocks contact with the fibers, so mopping stays out of the way. The roller, the heated wash and the two water tanks are most of what separates this from a vacuum-only robot, and a carpet-only home leaves that unused.
ROIDMI EVA
Buyers wanting any form of manufacturer support
Roidmi has ceased operations and discontinued product maintenance, returns, and after-sales service.
Large homes needing a single uninterrupted cleaning run
An independent review found the dustbin fills too fast to complete a full-floor clean without manual emptying.
Buyers relying on the dock to fully dry mop pads unattended
The same independent review found pads remained damp more than 12 hours after the drying cycle.

What stays your job

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

Ecovacs Deebot X12 OmniCyclone
  • After every mopping run: No owner task. The station washes the mop roller in heated water and dries it with hot air.
  • Weekly: Refill the station’s 3.5 L clean water tank and empty the 2.7 L dirty tank.
  • Up to every 48 days: Empty the station’s 1.6 L cyclonic container, the interval Ecovacs rates it at. The quick-clean scraper ring clears dust off the filter in the same operation.
  • Monthly: Rinse the cyclone filter; wipe the robot’s sensors and the station tray.
  • Every 3-6 months: Inspect the 10.6-inch mop roller and the side brush for wear and replace as needed.
ROIDMI EVA
  • Cadence: Empty the dust bag roughly every 60 days, per manufacturer specification.
  • Water tanks: Refill and empty the dock’s dual clean/dirty water tanks.
  • Mop pad drying: An independent review found pads remained damp more than 12 hours after the dock’s drying cycle, which in practice may require manual intervention.
  • Setup: Define no-go and no-mop zones in the app.
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.
