The EON is Dolphin's cordless robot that reaches where others cannot: steps, corners, sun ledges and safety ledges as shallow as 8 inches. Compare the EON 100 and EON 120D, including the Nautilus EON editions sold on Amazon, then see the corded ProLine™ and Max-Series™ robots we ship free.
Two robots, two editions each. The Nautilus EON 100 and Nautilus EON 120D are sold on Amazon with a 1-year warranty; the pool-store EON 100 and EON 120D carry 2 and 3 years. The 120D adds DebrisLock™ self-cleaning backwash filtration and UltraRun™ for up to two weeks of cycles per charge.

Most robots clean the floor, walls and waterline. The EON adds the parts of the pool that collect the most dirt: steps, benches, corners, tanning ledges and safety ledges as shallow as 8 inches, with JetIQ™ boosting grip on stairs and uneven surfaces. SmartMap™ navigation maps the pool and runs a methodical path.
With no cable there is nothing to tangle and no power supply by the pool: charge it, drop it in and schedule from the Maytronics One app whenever the robot is above the waterline.
The EON 100 uses a top-load fine filter basket with a full indicator and runs a 1.5, 2 or 2.5-hour cycle per charge. The EON 120D swaps in DebrisLock™ closed filtration with self-cleaning backwash, which Maytronics rates at 4x clearer water and about 20 hours of maintenance saved a year, and its UltraRun™ battery runs up to two weeks of scheduled cycles on one charge.
Start with your pool length and the coverage you need, then choose the filtration and controls that fit your routine. For recommendations across every Dolphin family, read our guide to the best robotic pool cleaners →
The Nautilus EON 100 and Nautilus EON 120D are the versions we list, sold through Amazon with a 1-year warranty. The pool-store EON 100 and EON 120D are the same robots with longer coverage: 2 years on the 100 and 3 on the 120D. Parts, manuals and fixes are shared.

SmartMap™ scans the pool before cleaning and plans a lane-by-lane route, so the robot covers the floor once instead of wandering. The app shows progress, sends alerts and walks you through troubleshooting.
