Best Dolphin Robotic Pool Cleaners (2026)

Think of the CC Plus Wi-Fi as the established corded design with a phone attached. The cable supplies power from a transformer on the deck, so there is no battery to age, and the active scrubbing brush works the surface as the machine climbs walls. The Wi-Fi link lets you set a schedule or start a cycle from the house, which the older plain models cannot do.

The included universal caddy is a bigger deal than it sounds, because a wet robot is heavy and awkward to carry. Compared with the Nautilus Titan above it in cost, the CC Plus Wi-Fi leaves out the waterline-focused scrubbing and the multi-layer filter, so it fits owners who do not fight a scum ring. The cable can twist, so uncoil it on the deck and let it hang straight.

Expect to rinse the top-load basket after every run, a job that takes a minute. Keep the transformer sheltered from rain and sun. The brush and tracks are the wear items to watch by year three.

The Titan is the machine to look at when the waterline is the problem. It adds a wall-to-waterline scrub to the corded platform, so the ring of oil and sunscreen at the surface gets attention each cycle. A multi-layer filter stack sits behind the intake to catch finer material than a single basket.

Its pick-up mode parks the robot at the water edge when the cycle ends, so you lift it from the deck instead of reaching for the cable. That is a real convenience for anyone with a bad back. Against the Nautilus CC Plus Wi-Fi it is the more capable and more expensive machine, and the extra cost only pays off if waterline cleaning matters to you.

A multi-layer filter needs more frequent rinsing than a single basket, so budget a few minutes after each run. Check the app after firmware updates to confirm the schedule survived. Coil the cable on the deck between uses.

The Nautilus AG is the only model here named for its pool type. Above-ground pools have shallower, softer walls and often vinyl liners, and a robot designed for them keeps the climb gentle. The active scrubbing brush works against the liner, which is why gentle matters.

Setup is as plain as it gets: plug in the transformer, drop the robot in, press start. That simplicity is the selling point, since there is no app, no battery and no pairing. Compared with the Escape, which also lists above-ground use, the AG is the machine with a clearer pedigree for that pool type, though both do the basics.

Rinse the top-load basket after each run and inspect the brush for wear, since a worn brush is the most likely cause of liner scuffing. Store it out of the sun, and keep the cable loosely coiled. Because above-ground pools are easy to drain and refill, a quick check for hair around the tracks is worth the thirty seconds.

The Escape is the budget entry that still carries the brand's key hardware: a HyperBrush roller, continuous HyperGrip tracks and a debris cartridge the maker says holds up to 60 percent more than its older design. Two low-voltage DC motors split drive and suction, which is gentler on the electrical side of the pool. It lists suitability for both above-ground and in-ground pools.

The tradeoff is features. There is no phone control and no waterline brush, so you set it by hand and clean the ring yourself. Against the Nautilus AG, the Escape claims more flexibility on pool type but less specialization. A large cartridge means fewer stops to empty it in leaf season.

Upkeep centers on the cartridge, which should be emptied and rinsed after every run. The tracks pick up hair, so check them monthly. Because it is the least costly Dolphin, treat it as a workhorse and keep a spare cartridge if you can find one.

The EON 120D is the longest-running cordless Dolphin on this list, with a stated 4.5 hours and multiple modes including floor-only and waterline-only. That runtime gives margin for a pool up to fifty feet long, which is the size the maker names. Wi-Fi control lets you schedule and monitor it from the house.

It costs noticeably more than the plain corded Dolphins, and a lithium pack is the price of freedom from the cable. Compared with the EON 100 it nearly doubles the stated run window, so it suits larger pools. Battery capacity will decline over several seasons, so the runtime figure is a new-pack number.

Charge after every run and store the robot shaded, because heat is the battery's worst enemy. The filter basket needs a rinse each time. Confirm the retrieval method before buying, since a heavy wet cordless unit is still a lift.

The EON 100 is the smaller, shorter-running sibling of the EON 120D. A stated 2.5 hours of runtime is enough for a typical residential pool when the water is clean, and the machine still climbs walls and scrubs the waterline. It brings the same Wi-Fi app and the same pool size claim of up to fifty feet.

The compromise is time. On a leafy pool, 2.5 hours can run out before the job is done, and the robot will park mid-cycle. Against the Nautilus CC Plus Wi-Fi, it trades unlimited corded runtime for tangle-free convenience.

Plan a charge after each run and shade it between uses. Keep an eye on the brush and tracks each season. If your pool is large or dirty, step up to the EON 120D instead of asking this model to carry the load.
