Best for
A cordless Dolphin for pools with steps and shallow ledges, with ultra-fine filtration. Read runtime as cycle length plus charging interval.
Look elsewhere if
Buyers who want a self-emptying station or surface skimming, or pools longer than 50 ft.
What the EON 120d is
The EON 120d is the upper model in Maytronics' first cordless Dolphin line, introduced at CES Unveiled in January 2026. Maytronics positions it on coverage: floor, walls, waterline, steps, corners and tanning ledges as shallow as 8 inches.
It adds DebrisLock ultra-fine filtration, which the EON 100 does not have, and connects to the Maytronics One app over Wi-Fi.
Read the specifications correctly
Maytronics publishes several runtime figures. The product page lists cleaning cycles of 1.5, 2 or 2.5 hours and an UltraRun claim of up to 2 weeks of pool cleaning on one charge; the September blog says up to 4 hours per charge. These describe different things, so read cycle length and charging interval separately.
The 50 ft rating is a maximum pool length, not an area figure.

Who should shortlist it
Shortlist the EON 120d for pools with steps, benches or shallow ledges where coverage matters more than surface skimming. Compare it with station-equipped rivals if hands-free charging and emptying are priorities.

WCB interpretation: The EON 120d competes on step and ledge coverage and filtration; Beatbot adds a self-cleaning station and surface skimming at a higher price tier.

WYBOT S3

Aiper Scuba S3
A 2026 cordless pool cleaner with WavePath 2.0 and dToF navigation, a 3.5-litre filter basket and up to four hours in Eco mode.
View modelMaintenance and ownership
Empty and rinse the top-access filter after each cycle; ultra-fine filters clog faster in pools with heavy debris. App functions work only when the robot is above the waterline.
The robot weighs about 24 lb, so lifting it out at the waterline is part of the routine. The warranty is 3 years.
