Ringside notes
Our robotic skimmer showdown ruled this one emphatically: the Betta SE Plus took best overall AND best value, and the iSkim Ultra is the premium pick only for owners who want its built-in clarifier and side brushes — the rare fight where the cheaper machine wins on the merits, not the price. The core fact that decides it: both skimmers run the same 2.5-inch propellers, so the iSkim — $999 list, about $699 on Amazon — doesn't actually skim harder than the ~$390 Betta. What Beatbot charges the premium for is the extras — a clarifier dispenser, dual side brushes and twenty sensors. What the Betta answers with is the strongest owner record in the category (4.5★ across 3,089 — the deepest clean base behind any skimmer we rank with adapter backup — only the plain Betta SE, at 8,271, has more owners), solar power with an AC-adapter backup so a cloudy week doesn't beach it, and a drip-free top-loading debris basket. The iSkim's owners land at 3.9★ across 25. If you genuinely want to talk to your skimmer, that feature exists and it works. If you want the surface cleaned, the ruling says keep the $600.

What would decide it
- Owner proof: Betta SE Plus reads 4.5★ across 3,089 owners; Beatbot iSkim Ultra reads 3.9★ across 25. Depth of sample matters as much as the star.
- The money: Betta SE Plus streets ~$390, Beatbot iSkim Ultra ~$699 — MSRPs, not sale lows, decide the tier.
- Betta SE Plus — your pick if: you want a surface skimmer that never quits — solar with AC-adapter backup so a week of clouds doesn't sideline it, plus a shallow-water safeguard that keeps it off your pool stairs (4.5★ across 3,089).
- Beatbot iSkim Ultra — your pick if: you want the most equipped skimmer Beatbot makes — seven motors driving dual side brushes, twenty sensors and a built-in water-clarifier dispenser are what the premium buys, and WIRED's August 2026 test rated it the best surface skimmer tested. The skimming itself runs on the same 2.5-inch propellers as a $370 Betta.

“After hands-on testing, I found that the Betta SE Plus stood out as the top performer—it was incredibly easy to set up and removed more leaves and floating debris than any other model I tried.”
Best Overall of Bob Vila's 2026 robotic-skimmer test (published 2026-07-24). Methodology on the page: "For hands-on testing, I used each robotic skimmer in residential inground pools over multiple days, including both screened-in and open-air pool environments." The tester is Florida-based. Their Buy-at-Amazon link resolves to B0CVMQ3XBX, the listing we card. Supersedes The Pool Nerd's August 2025 review ("It's efficient, quiet, and low-maintenance."), which is now older than a year.

- Solar plus USB-C/AC backup — keeps skimming through cloudy stretches
- Top-loading 200µm basket lifts out without dribbling debris back in
- Twin salt-chlorine-tolerant motors handle treated water
- Covers up to ~2,400 sq ft, in-ground or above-ground
- 2.5-in propellers — less grab than the Dolphin's 3-in in wind or heavy leaf fall
- 1-year warranty (Beatbot gives two)
- Wireless remote only — no phone app
It strands itself on a beach or zero entry and hangs up on pool-sweep hoses; separately, battery life and the status lights degrade inside the first year.

Beatbot iSkim Ultra
Premium pick — for the clarifier and side brushesYour pick if you want the most equipped skimmer Beatbot makes — seven motors driving dual side brushes, twenty sensors and a built-in water-clarifier dispenser are what the premium buys, and WIRED's August 2026 test rated it the best surface skimmer tested. The skimming itself runs on the same 2.5-inch propellers as a $370 Betta.
“Despite all these premium features, it's running 2.5-inch propellers—the exact same size you'll find on the $370 Betta SE.”— The Pool Nerd · Best splurge
Pro review “Compared to all other skimmers I've tested, this one does the best job.”Best Surface Skimmer in WIRED's robotic-pool-cleaner test (published 2026-04-23, updated 2026-08-21) by a reviewer who states four years of professional pool-robot testing; first-party photographs of the unit in his own L-shaped pool. His one catch: the basket-release button sits on the nose and about twice a month a corner clip ejects the basket into the pool. Their Amazon link resolves to B0GL27MPG8, the listing we card. NOTE the split verdict: The Pool Nerd's August 2025 hands-on called it 'a beautiful skimmer with the wrong priorities' (Pool Nerd Disapproved) — that view is kept in this card's cons.— Christopher Null, WIRED
- 7 motors + 20 sensors + WiFi app scheduling — the most automated skimmer here
- Huge 9L basket with one-touch release
- 2-year full-replacement warranty
- Saltwater rated to 5,000 ppm
- Runs the same 2.5-in propellers as the $370 Betta SE — you're paying for features, not suction
- By far the most expensive
- Side-loading basket
- Testers split: WIRED (Aug 2026) rates it the best surface skimmer they have tried; The Pool Nerd (Aug 2025) called it "a beautiful skimmer with the wrong priorities" that "doesn't clean much better than models that cost half as much."
The solar charging is what owners report failing — a unit dying daily until it turned out solar was not charging at all, another dead on the second day, one dead out of the box. App-to-robot pairing is the other thread, with support reachable only by email. One notes nothing protects it from the pool's coping edge. Even the mildest critical card praises the support and marks the product down.

FAQ
Which is better, the Betta SE Plus or the Beatbot iSkim Ultra?
Our robotic pool skimmer showdown ruled for the Betta SE Plus — best overall and best value — and made the iSkim Ultra its premium pick only for its clarifier and side brushes. Both run the same 2.5-inch propellers, so the premium buys a clarifier dispenser and side brushes, not stronger skimming. Owners agree: 4.5★/3,089 for the Betta vs 3.9★/25.
What does the iSkim Ultra actually do better?
The smart layer: app control and voice commands, in the Beatbot ecosystem. If that convenience is worth the price gap to you, it's a real feature — but its propulsion hardware matches the far cheaper Betta, which is why the ruling went the way it did.
Is the Betta's solar power reliable enough?
That's its quiet advantage: solar with an AC-adapter backup, so a stretch of cloudy days doesn't strand it — plus a drip-free top-loading basket for cleaner emptying. The 3,089-owner base at 4.5★ is the deepest clean base behind any skimmer we rank (only the plain Betta SE, at 8,271, has more owners).
