Why Dolphin Nautilus EON 120D?
Up to 4.5 Hours per Charge
Nearly double the runtime of the EON 100. Up to 4.5 hours on a charge is a full pass on a 50 ft pool with margin to spare, or an eco cycle that runs most of the day.
Five Cleaning Modes
Floor-only, waterline-only, regular, smart run and eco. Send it straight at the tile band when only the waterline has gone grey and save the battery for the rest.
Wi-Fi App Control
The MaytronicsOne app lets you start, stop, schedule and customize cleaning modes from your phone while the robot is out of the water.

DESIGNED FOR IN-GROUND POOLS UP TO 50 FT
The Step-Up Cordless Nautilus.
The Dolphin Nautilus EON 120D is the EON 100 with a much bigger battery and finer filtration. Up to 4.5 hours of runtime removes the main practical limit on cordless cleaning, five modes let you target the floor or the waterline on their own, multi-layer cartridge filtration catches the ultra-fine debris that clouds water, and automatic edge return brings the robot to the side for pickup.
What's Included
The Dolphin Nautilus EON 120D arrives ready to charge and clean. There is no floating cable and no poolside power supply, just the robot, its charger and the filter cartridges.

RUNTIME CHANGES WHAT'S POSSIBLE
4.5 Hours on a Charge
At 2.5 hours a cordless robot is racing the clock on a 50 ft pool. At 4.5 hours it can do a genuine full pass with margin, or run an eco cycle for most of a day. That is the difference between a machine you plan around and one you do not think about.
FIVE MODES
Floor, Waterline, Regular, Smart Run, Eco
Waterline-only is the underrated one: when the floor is fine and only the tile band has gone grey, send the EON 120D straight at the waterline and use a fraction of the battery. Smart run maps the pool for full coverage of the floor, walls, waterline, stairs, corners and sun ledges down to 8 inches of water, and eco stretches the charge on a well-kept pool.
MULTI-LAYER FILTRATION
Ultra-Fine Debris, Caught
Multi-layer cartridge filtration captures the ultra-fine particles that cloud water alongside the leaves and larger debris, a step up from the plain basket on the EON 100, and it takes strain off the pool's main filtration system. The cartridges lift out the top for a rinse.
Automatic Edge Return
When the cycle ends, the EON 120D drives itself to the edge of the pool and waits, so you lift it out by the handle without stretching over the water or fishing with a pole.
CONTROL, SCHEDULE & MORE
MaytronicsOne App
Connect the EON 120D to your home Wi-Fi and the MaytronicsOne app lets you start and stop the robot, set a schedule and choose one of the five modes from your phone. Set it up while the robot is out of the water, then drop it in and let it run.

Questions about the Nautilus EON 120D
How long does it run on a charge?
Up to 4.5 hours, depending on the mode: roughly double the EON 100. That is a full pass on a 50 ft pool with margin, or an eco cycle that runs most of a day.
What cleaning modes does it have?
Five: floor-only, waterline-only, regular cleaning, smart run and eco. Waterline-only sends the robot straight at the tile band and uses a fraction of the battery.
What does multi-layer filtration catch?
The cartridge filtration captures ultra-fine debris as well as the larger particles that cloud water, and takes strain off the pool's main filtration system. The cartridges lift out of the top for a rinse.
How do I get it out of the pool?
At the end of the cycle the EON 120D returns to the pool edge on its own and waits, so you lift it out by the handle without reaching over the water.
Which app does it use?
The MaytronicsOne app over Wi-Fi. You start, stop, schedule and choose a mode from your phone while the robot is out of the water.
Where can I buy it?
The Nautilus EON 120D is sold through Amazon; the button on this page takes you to the current Amazon price. For a cordless Dolphin with free shipping, a 30-day trial and no restocking fee from us, see the Liberty 200.
