Cordless Convenience, Unmatched Coverage: How Eon Delivers Reliable Pool Cleaning Without Sacrifice
If you’ve owned a cordless robotic pool cleaner before, you already know the frustration. The freedom is real no tangled cords, no awkward cable management, just drop it in and go.
But then reality sets in, the battery dies halfway through a cleaning cycle, the suction fades as the charge drops, or you discover that your walls and steps are still covered in algae because the robot never made it that far.
For too long, “cordless” has come with an invisible asterisk. The EON, available online as the Dolphin Nautilus EON, is built to change that.
Runtime That Matches Your Pool's Needs, Not Just the Spec Sheet
Many budget cordless robots offer 1.5 to 2.5 hours of runtime. For a larger pool, that’s often not enough to finish the job—and you’re left manually picking up where the robot left off.
The Dolphin Nautilus EON 120d delivers up to 4 hours of runtime on a single charge. Combined with its advanced ECO mode and smart scheduling, the EON can keep your pool clean for up to 2 weeks without constant attention.
That’s not convenience as a compromise. That’s convenience as a feature.
Full Power from Start to Finish
Many cordless pool robots on the market start strong and fade fast. As the battery drains, suction weakens and the debris that matters most, the stuff stuck to your pool stairs, benches and ledges, doesn’t get picked up.
The Dolphin EON’s is engineered to maintain consistent suction power throughout the entire cleaning cycle. From the first minute to the last, you get the same reliable performance, what you see at the start of a cycle is what you get at the end.
No Blind Spots. No Manual Touch-Ups.
Full pool coverage sounds like a given, but it’s where a lot of cordless robots fall short. The Dolphin’s EONs’ intelligent navigation is designed to reach every surface, including:
• Floors
• Walls
• Steps
• Benches
• Corners
• Shallow sun ledges as little as 8 inches deep
That last point matters more than most people realize. Sun ledges and shallow entry steps are notorious hiding spots for algae and debris and most robots simply skip them. The Dolphin EON doesn’t. The result is a genuinely clean pool, not just a mostly clean one.

Smart Filtration That Keeps Itself Ready
The Dolphin EON's patented DebrisLock™ filtration system automatically cleans the filter while the robot is still in the pool, sensors detect clogs and trigger a backwash cycle, trapping dislodged debris in a sealed compartment. The result is optimal water flow between sessions, performance that doesn't degrade, and up to 20 hours saved on maintenance per season.
Built for the Long Haul and Backed to Prove It
The Dolphin EON Robotic Cleaners is built on over 40 years of Maytronics engineering, the same company that has deployed millions of robotic pool cleaners across the globe. That heritage shows up in the quality of materials, the precision of the engineering, and the reliability that holds up season after season.
And Maytronics backs it with a comprehensive warranty covering parts and labor, plus an extensive network of authorized service centers. If something ever goes wrong, you’re not on your own.
Don’t Take Our Word for It
In the Press
The Dolphin EON line made its debut at CES Unveiled in Las Vegas (January 2026), where it was recognized as a breakthrough in robotic pool cleaning technology. Here's what the industry is saying:
GlobeNewsWire / Maytronics Official Press Release:
"The Dolphin EON line represents a breakthrough in pool cleaning technology: the first robot that reaches and cleans every inch of a pool."
Franck Sogaard, CEO Americas at Maytronics:
"Our message with the Dolphin EON is simple and clear: it knows your specific pool and cleans it all. We are extremely confident in our promise that the EON cleans more thoroughly than any other pool cleaner on the market today, and that your pool will sparkle brighter as a result of the technology we've embedded in the robot."
PCWorld (Christopher Null):
"The Dolphin Eon series promises to work in shallow water, areas with as little as 8 inches of coverage, making them usable on steps, shelves, ledges, and zero-entry slopes."
AQUA Magazine:
"With total-pool coverage and innovative filtration technology, EON's clever design means pool owners can enjoy visibly cleaner water, 4x clearer than competing products."
Pool Pro Magazine:
"The Dolphin EON is capable of operating in water as shallow as 8 inches, allowing it to clean tanning ledges and Baja shelves that typically require manual maintenance."
The EON 120d even sold out due to demand exceeding expectations, a testament to its next-level performance and the market's appetite for a truly no-compromise cordless cleaner.
Frequently Asked Questions About the Dolphin Nautilus EON
Can the Dolphin EON clean shallow sun ledges and tanning shelves?
Yes. The Dolphin EON is designed to clean in water as shallow as 8 inches. Its low-mounted impeller and JetIQ™ jet technology allow it to operate on sun ledges, Baja shelves, benches, and shallow entry steps that other robots skip entirely. Both the Nautilus EON 120d and EON 100 include this capability.
Does the Dolphin EON clean walls and stairs?
Yes. The Dolphin EON uses JetIQ™ intelligent jets to lift itself over stairs and navigate walls. The Nautilus EON 120d also scrubs the waterline. SmartMap Navigation tailors cleaning paths to your pool's specific shape, covering floors, walls, steps, corners, benches, and shallow ledges in pools up to 50 feet long.
What's the difference between the Dolphin Nautilus EON 120d and Dolphin Nautilus EON 100?
Both models clean floors, walls, steps, corners, sun ledges, and safety ledges in pools up to 50 feet. The EON 120d adds waterline scrubbing, DebrisLock™ backwash filtration, and extended runtime. The EON 100 uses a 70-micron fine filter and starts at $899 versus $1,199 for the 120d.
