Quick Answer: The Dolphin EON 100 is Maytronics’ first cordless robotic pool cleaner, rated for in-ground and above-ground pools up to 50 ft with a battery Maytronics markets as running up to 1 week per charge. It’s sold under two nearly identical SKUs with real spec differences: the plain EON 100 (2-year warranty, waterline scrubbing included, no published online price) and the Nautilus EON 100 ($899 direct from Maytronics, but only a 1-year warranty and waterline scrubbing listed as “No” on its own spec sheet).
Dolphin has sold corded robots for decades, but the EON 100 family is its entry into the cordless market Beatbot, Aiper, and WYBOT have dominated so far — and Maytronics’ own product pages show the two EON 100 SKUs aren’t quite the same cleaner.

By the numbers
- Battery runtime: Maytronics markets the UltraRun system as running up to 1 week of pool cleaning on one charge — dramatically longer than cordless competitors like the Aiper Scuba S1 or Beatbot AquaSense 2, which typically run 60-150 minutes per charge and need recharging after a single cycle.
- Suction rate: Maytronics lists 4,000 GPH specifically for the Nautilus EON 100’s spec sheet — the plain EON 100’s own product page omits a suction figure entirely.
- Warranty gap: 2 years on the plain EON 100 vs 1 year on the Nautilus EON 100 — the same gap this site has already flagged on the corded Dolphin Nautilus CC line, where Maytronics also cut coverage on a specific SKU family.
- Max pool size: Both SKUs are rated for in-ground and above-ground pools up to 50 ft, matching the coverage of Dolphin’s corded Explorer E50.
What it does well
A genuinely long runtime for a cordless robot. A battery that lasts up to a week between charges removes the “did I remember to charge it” friction that comes with most cordless cleaners needing a recharge after every single cleaning cycle.
Full coverage on the plain EON 100 SKU. Floor, walls, and waterline scrubbing on a cordless unit, with no cable to tangle around ladders or steps.
App-based scheduling via Maytronics One, the same ecosystem used across Dolphin’s corded lineup, so switching between a corded and cordless Dolphin model doesn’t mean learning new software.
Where it falls short
- Two SKUs, two different products, one near-identical name. The plain EON 100 and the Nautilus EON 100 share almost the same name but differ on warranty length and whether waterline scrubbing is included — confirm the exact SKU before buying, not just the product name.
- No suction figure published for the plain EON 100. Only the Nautilus EON 100’s spec sheet lists a 4,000 GPH figure; buyers of the other SKU have no comparable number to judge cleaning power against.
- The plain EON 100 has no published online price. It’s marked “Store Exclusive,” so getting an actual price means contacting a local Buy Local retailer rather than checking out directly.
- Only a 1-year warranty on the Nautilus EON 100, shorter than most of Dolphin’s corded lineup and shorter than the 2-year coverage on its own plain-EON-100 sibling.
Dolphin EON 100 vs the alternatives
| Model | Type | Runtime/cycle | Warranty | Price |
|---|---|---|---|---|
| Dolphin EON 100 | Cordless | Up to 1 week/charge | 2 years | Store Exclusive |
| Dolphin Nautilus EON 100 | Cordless | Up to 1 week/charge | 1 year | $899 |
| Dolphin Explorer E50 | Corded | 2hr cycle | 2 years | $1,329 sale |
| Aiper Scuba S1 | Cordless | ~3hr/charge | 1 year | $549.99 sale |
The EON 100 family’s week-long battery life is its real differentiator against cordless rivals like the Aiper Scuba S1, which need a recharge after every use. Against Dolphin’s own corded Explorer E50, the trade is the usual cordless-vs-corded one — no cable, but a battery to manage — except here the battery barely needs managing.

Who should buy the Dolphin EON 100
Buy it if you want Dolphin’s app ecosystem and wall-climbing in a cordless cleaner with a genuinely long runtime, and you’re willing to confirm which exact SKU — plain EON 100 or Nautilus EON 100 — you’re actually ordering before you check out.
Look elsewhere if you want waterline scrubbing AND a published online checkout price in the same purchase (the two EON 100 SKUs currently split those features between them), or if a published independent suction measurement matters to you — neither SKU has one yet.
The bottom line
The Dolphin EON 100 brings Maytronics’ first cordless cleaner to market with a standout week-long battery claim, but the family ships as two nearly identically named SKUs with real spec differences — a 2-year warranty and waterline scrubbing on the plain EON 100, versus a $899 online price but only 1 year of coverage and no waterline scrubbing on the Nautilus EON 100. Check the exact SKU, not just the name, before you buy.
