Solar Pool Skimmer Model Comparisons
Betta Flex vs SE: Pool Fit, Eco Mode and Solar Charging
Choose between SE’s 5-inch operating minimum and Flex’s low-profile body, Eco mode and 6-inch minimum. Flex does not operate in shallower water just because it looks flatter. Both are solar-only with no AC, DC or USB charging port. If adapter backup is essential, compare SE Plus instead.

Check current price Read the model guideBoth depend on sunlight
The SE and Flex manuals explicitly state that these models have no AC, DC or USB charging port. If reliable adapter charging is your main requirement, move to a different comparison instead of assuming Flex includes it.
Check direct sun on the water through a normal day. Trees or a roof can shade the pool while the rest of the yard stays bright. Record the sunny areas the robot can reach before choosing either solar-only model.
Flex changes the operating routine
Flex provides Normal and Eco modes. Its manual describes Eco operation pausing after four hours, with the pause adjusted to battery level. A planned pause is therefore different from a mechanical failure.
Consider whether intermittent skimming suits your debris pattern. Light, scattered debris may make a periodic routine appealing. If leaves collect rapidly at particular times, observe those periods carefully during initial use. We have not measured a cleaning advantage for either model, and mode labels alone cannot establish how quickly your pool will clear.
Low profile does not mean shallower water
Betta’s FAQ gives minimum depths of 6 inches for Flex and 5 inches for SE. The Flex product page describes a lower-profile, soft-touch body and lists infinity-pool compatibility. Those are separate design claims from minimum water depth.
For an infinity edge, obtain approval for your specific layout and flow conditions. For a sun shelf, measure actual water above the shelf. A robot can be compact above the water and still need clearance underneath. Do not choose Flex just because a photo makes it look flatter.
Resolve package differences before checkout
The Flex product comparison and manual are inconsistent about remote-control availability: the comparison marks no remote while manual text calls an optional remote included. SE's current documentation identifies a handheld remote. Confirm the Flex package instead of treating the family resemblance as evidence.
Flex's manual also conflicts with itself about simultaneous operation: its safety section says not to use another cleaner, while a later anti-tangle section describes a wired underwater cleaner. Follow the supplied manual and obtain Flex-specific written guidance. If adapter backup is required, compare SE Plus or Neo instead.
Common questions
Does Betta Flex charge with USB?
No. Its manual explicitly excludes AC, DC and USB charging ports.
Does Flex need less water depth than SE?
No. Betta lists 6 inches for Flex and 5 inches for SE.
Is a pause in Flex Eco mode a fault?
Not necessarily. Eco mode includes deliberate pauses; use the light pattern and current manual to distinguish normal behavior from a problem.
Is a Flex remote included?
The manufacturer materials are inconsistent. Confirm the precise package before purchase.
