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

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.
Aiper Surfer S1
Solar power offers maintenance-free charging and zero-electricity operation, but runtime depends entirely on weather and season, creating predictable gaps on cloudy days.
Unmapped navigation needs no calibration or boundary setup, yet it also means no way to direct the unit at a particular part of the surface.
Waterline-only design eliminates floor-cleaning overhead and cost, but leaves sinking debris untouched and suits only specific pool conditions.
Betta SE
Solar self-charging removes the need to plug the unit in, but the base SE model has no app control and no self-docking, so retrieval and status checks are fully manual.
A narrower, single job (surface skimming only) is done with a simpler design than a floor-and-wall robot, but it also means this unit cannot substitute for one; a pool still needs separate floor and wall cleaning.
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.
Aiper Surfer S1
- Pools requiring floor or wall cleaning
- Surfer S1 does not address sinking debris, algae, or bottom accumulation. Owners needing comprehensive coverage should pair with a floor cleaner or choose dual-function alternatives.
- Pools with little direct sun on the water
- The Sunseeker behavior recharges the pack by moving the unit into sunlight. A pool under permanent cover or dense shade removes that path, and the unit's ability to run itself indefinitely with it.
- Owners expecting programmed cycles
- Aiper's published app description covers manual control, battery status and pool temperature. No scheduling function is published, so sessions are started rather than programmed.
- Water above the rated salinity
- Aiper states the Surfer S1 works in standard, saltwater and natural pools up to 6,500 ppm NaCl. Water held above that figure is outside the published rating.
- Owners wanting one machine for the whole pool
- The Surfer S1 works the water surface. Floors, walls, steps and the waterline are outside what it does, and Aiper sells separate machines for those.
Betta SE
- Owners expecting floor, wall or waterline cleaning
- This is a surface skimmer only; it does not reach the pool floor, walls or waterline the way the other robots in this category do.
- Owners who want app-based monitoring or scheduling
- The base SE model has no app control, per the manufacturer's own comparison; that requires the higher-tier SE Plus.
- Buyers who require independently verified reliability data before purchase
- No independent, non-manufacturer test of the Betta SE was located during this research.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Aiper Surfer S1
- As the basket fills: Lift the unit out, empty the 5 L filter basket and rinse the 200 micron element. The unit is designed to live in the pool between emptyings rather than be removed after each session.
- Monthly: Wipe the solar panel with a soft cloth to restore charging output.
- Every 3-6 months: Inspect the propeller and housing for cracks or deformation.
- Seasonally: Store the unit dry and indoors over a closed season, with charge in the pack rather than run flat.
- Annually: Inspect the intake gasket and seals, and replace if visible wear has developed.
Betta SE
- Weekly: Wipe the solar panel and check the propellers and impeller for dirt, string, or hair; the owner’s manual names both in troubleshooting but publishes no interval.
- Monthly: Confirm the adjustable bumper rods are secure and set for the pool’s shallow sections.
- Seasonally: Retrieve and store the unit indoors over the closed season. It charges only from its solar panel (there is no AC charging port), so let it charge in sun before storage rather than storing it flat.
- As needed: Empty the 200-micron debris basket by its top handle and rinse the mesh; cadence depends on debris load, and the manufacturer publishes no interval.
- As needed: Reposition or retrieve the unit by hand at the pool edge; it does not dock, return, or report status on its own (no app on the base SE).
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.
