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.
These robots share no measured specification with enough published figures to plot. That is a gap in the record, not a finding about the robots.
04 Ownership
What the numbers leave out.
The trade-off
What each design gives up to be good at what it is good at.

Not recorded for this robot.
Seauto SAT40
The manufacturer claims coverage of all core pool surfaces (floor, walls, waterline) plus corners, but no independent source confirms how completely or consistently that coverage happens in practice.
A lower list price than some competitors in this batch comes with a thinner independently verifiable record: no confirmed warranty term and no accessible third-party reliability evidence.
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.

Seauto SAT40
- Buyers who need independently verified reliability data before purchase
- No non-manufacturer review, forum, or repair source for the SAT40 was accessible during this research.
- Buyers who require a stated, confirmed warranty term
- No warranty term was found on the manufacturer's product page.
- Above-ground pools as the primary use case
- The manufacturer states the unit is designed primarily for inground pools, though it states above-ground use is possible.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.

Seauto SAT40
- Filter cartridges: The dual filtration cartridges (250 micron and 10 micron) require manual rinsing after each use.
- Setup: Cleaning mode is selected via the app; the manufacturer states Bluetooth/app control.
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.
