EON
The Dolphin Nautilus EON 120d is the cordless robot that removes the two chores that come with cordless robots: charging and filter cleaning. UltraRun scheduling stretches one charge across up to 2.5 weeks of cleaning sessions, and the DebrisLock filter, a sealed 14-micron basket with a built-in backwash, compresses what it catches and flushes it at the end of every cycle, so you empty it about once a week. Maytronics puts the saving at 20 hours a year and the water at up to four times clearer in its own tests.
The cleaning itself matches the EON 100: floor, walls, waterline, steps, corners and tanning ledges in as little as 8 inches of water, in inground and above-ground pools up to 50 ft, with SmartMap navigation planning the route and JetIQ jets keeping grip on stairs. The Maytronics One app sets schedules, modes and alerts when the robot is out of the water. This Nautilus edition carries a one-year warranty; the pool-store Dolphin EON 120d is the same robot with three years. Pool Express is an authorized Maytronics dealer.
A closed 14-micron basket with 4-litre capacity that compresses debris and backwashes itself at the end of each cycle, cutting filter cleaning to about once a week.
Schedule a weekly plan and the robot cleans floor, walls, waterline, steps and ledges for weeks without a recharge.
Steps, corners, safety ledges and sun ledges as shallow as 8 inches, plus the floor, walls and waterline.
Learns the shape of the pool and tailors the cleaning program to it.
Water jets boost grip and movement on stairs and uneven surfaces.
Schedules, modes, alerts and software updates when the robot is above the waterline.

Same robot, different channel. The Nautilus EON 120d is the online and retail edition with a one-year warranty; the Dolphin EON 120d is the pool-store edition with a three-year warranty.
About once a week in normal use. The filter backwashes itself at the end of each cycle and whenever it is full, which is why the robot can stay in the pool for weeks of scheduled cleaning.
Cordless Maytronics robots, including the EON and the Liberty 400 and 600, lose their Wi-Fi and Bluetooth connection as soon as they are under water. That is normal. Connect the robot to the app before you put it in, set the cleaning mode or weekly schedule you want, then place it in the pool and it runs the program on its own. When you lift it out, the connection comes back automatically. Corded Dolphins stay connected the whole time because the power supply on the deck does the talking. Note that the Liberty 400 pairs by Bluetooth only, through the MyDolphin Plus app.
Maytronics' cordless robot built for total coverage: floors, walls, waterline, steps, corners and ledges in water as shallow as 8 inches, with no cord to manage and no booster pump or hose.
Inground pools up to 50 feet long. Within that, it cleans the floor, walls, waterline, steps, corners and tanning ledges as shallow as 8 inches.
Up to two and a half weeks of scheduled cleaning, thanks to the UltraRun battery system. Set a weekly plan in the app, leave the robot in the pool and it runs its cycles on its own, with no cords, hoses or booster pump.
