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.

Generalized
Any task, any setting
IV
Environmental
Handles new obstacles without help

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.

Ecovacs GOAT A2000 LiDAR PRO

The trimmer removes most edge work on a tidy border, and on an irregular one it is where the mower gets stuck.

Wire-free LiDAR setup takes minutes; blades wear out every 4 to 6 weeks, per the manual.

Sunseeker Elite X4

No antenna and no wire make setup quick, and the edges still need a trimmer.

Navigation stayed consistent for T3; drops and complex layouts are where auto-mapping falters.

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 GOAT A2000 LiDAR PRO
Yards with brick edging, retaining walls or irregular borders
EFTM had to mark no-go areas along brick fences and a rock wall because the mower was coming unstuck too often, and it needed repeated recovery.
Overgrown lawns expecting one-tap automatic mapping
Digital Reviews found automatic mapping failed on an overgrown backyard and had to drive the mower around the boundary by hand.
Owners who want square corners trimmed without touch-ups
EFTM reports the trimmer does not reach far enough into square corners, and it stops trimming when a person comes within about 1.5 m.
Households unwilling to change blades every few weeks
The manual lists blade replacement every 4 to 6 weeks and trimmer line and brush every 4 to 8 weeks.
Owners who prefer drawing no-go zones on a phone map
EFTM found it had to drive the mower into an area to mark it off rather than draw the exclusion on the map.
Sunseeker Elite X4
Owners who want edges finished by the mower
T3 reports that edges still need tidying up after the mower's pass.
Gardens with drops, terraces or intricate layouts
T3 found auto-mapping can struggle with drops or more complex layouts.
Owners who change cutting height often
Sunseeker's dealer spec sheet lists manual cutting height adjustment from 20 to 60 mm.
Lawns larger than about 1,200 m²
Sunseeker rates the X4 for lawns up to 1,200 m².
Owners who want deep app customization
T3 found the app leans towards simplicity rather than deep customization.

What stays your job

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

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.
