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

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.
None of these robots carries a scored assessment yet, so there is nothing to plot here. The classification and evidence below still apply.
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.
Degrii Zima Lite
Dual-ultrasonic-radar 3D path planning across floor, walls and waterline is a real capability by manufacturer design, but Degrii’s own regional listings disagree on how large a pool that planning actually covers, and this research could not reconcile the two figures.
Auto-parking at the nearest wall reduces how far a robot has to be fished from open water, but it still requires manual lifting rather than a full self-exit, so the retrieval task is reduced, not eliminated.
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.
Degrii Zima Lite
- Buyers who need a single, confirmed maximum-coverage figure before purchase
- Degrii's own EU and US listings state different maximum pool sizes for the same product, and this research could not resolve which applies.
- Pools with tall drains, ledges or fittings near 4 in or taller
- The manufacturer's documented maximum obstacle-clearance height is 3.9 in.
- Buyers who require independently verified cleaning performance before purchase
- No independent, non-manufacturer test of the Zima Lite was located during this research.
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.
Degrii Zima Lite
- Filter baskets: Dual 180-micron ultra-fine filters with 6.5 L combined capacity need periodic emptying.
- Retrieval: Auto-parks at the nearest wall on completion or low battery, but a person must lift it out by hand unless it parks within reach.
- Setup: Mode and schedule selection happen in the Degrii app over WiFi or Bluetooth.
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.
