The Betta SE is the skimmer to buy if you want one that has been in the market long enough for its problems to be known. Every other solar skimmer on this site is a 2024-2026 model; this design has several seasons of owner feedback behind it.
What it gets right
Salt-rated. Betta states salt and chlorine compatibility explicitly. Salt is harder on bearings and fasteners than chlorine, and a surface skimmer spends its entire life at the air-water interface where corrosion is worst. Not every skimmer states this, and you should not assume it.
Works in above-ground pools. Most skimmers implicitly assume a hard coping edge for their docking and recall behavior. Betta rates the SE for both pool types, which makes it one of the few genuine options for an above-ground pool — where a skimmer is unusually valuable, because above-ground pools are shallow and their built-in skimmers are typically small single-basket units. The above-ground roundup covers why.
Obstacle avoidance and continuous solar operation. It runs all day at no running cost, which is the fundamental appeal of the whole category: debris caught floating never sinks, never stains and never loads your filter.
The gap: no published basket volume
Betta describes the basket as “extra large” and gives no figure. That is a real problem, because basket volume is the one specification that decides a skimmer. A skimmer with a full basket is a floating ornament, so the only question that matters is how many hours of leaf fall it absorbs before you walk out to empty it.
For comparison: Beatbot publishes 9 liters for the iSkim and Aiper publishes 4 for the EcoSurfer S2. “Extra large” could be either. We are not going to estimate it, and if you are under a mature oak the Beatbot’s published figure is the safer purchase — compared head to head here.
Remote control, not an app
The SE uses a remote rather than a phone app. That means no scheduling and no recall from indoors — if the wind pins it in a corner, you deal with it at the poolside rather than from the kitchen. The iSkim’s app recall is genuinely more useful, and it is the main feature difference at this price.
And the thing every skimmer owner should know
It cleans the surface only. It will never touch your floor, walls or waterline. A skimmer is a complement to a floor robot, not a substitute — and the pairing of a corded floor machine with a solar skimmer removes more total debris than most single flagships, for less money. The skimmer roundup makes that case properly.
One more structural caveat: solar output drops under heavy tree cover, which is usually the reason you want a skimmer in the first place. In deep continuous shade, plan on charging it.
How we assessed it, and what we did not do
Every figure in the specification table on this page is attributed: to Betta’s published specifications, to the Amazon listing for this exact model, or marked as not published where neither source gives a figure. The score is derived from those published numbers by the five-metric rubric, which is published in full.
We have not physically tested this machine. We do not run a test pool, we do not own this unit, and nothing on this site claims otherwise. What we do instead is show where every number comes from, say plainly who the machine is wrong for, and refuse to print a figure we cannot source. Where owner reports inform a point, they are described as owner reports — never as our own experience.
Who should skip it
Skip the Betta SE if you want app scheduling, or you need a published basket figure to size against your leaf load.
That is not a throwaway line. The most expensive mistake in this category is buying a capable machine that is wrong for your pool — and a machine rated below your pool’s area or missing the one capability your debris requires cannot be fixed by any setting.
Alternatives worth considering
- Beatbot iSkim — a published 9-liter basket and app recall, for about $10 less. Read the review
- Aiper EcoSurfer S2 — adds a chlorine dispenser and a 35-hour battery, at a similar price. Read the review
- Beatbot Sora 70 — one machine that skims and cleans the floor, if you would rather not buy two. Read the review
