Maytronics' Dolphin line is deep enough to be confusing — corded and cordless, floor-only and full-coverage, budget and dealer-line. Here is the Dolphin to buy for each kind of pool and owner, each with a link to our full review.
Best overall: Dolphin Nautilus CC Plus
Mid-range · Corded · Floor & walls
The Dolphin Nautilus CC Plus is the one most people should buy: reliable floor-and-wall cleaning for an in-ground pool up to 33 feet, easy top-load filters, and a weekly timer. It runs off its own plug and is backed by the biggest service network in the category. No waterline scrubbing or app keeps it affordable. It is the safe first robot.
Best for leaves: Dolphin Premier
Luxury · Corded · Floor, walls & waterline
The Dolphin Premier's oversized, swappable leaf bag makes it the debris specialist for tree-heavy yards, with fine media on hand for the rest of the year. It cleans floor, walls, and waterline to 50 feet with a 3-year warranty. There is no app — the value is all in the cleaning system. For a leafy pool, its capacity is unmatched in the line.
Best cordless: Dolphin Liberty 600
Premium · Cordless · Floor, walls & waterline
The Dolphin Liberty 600 is the safest cordless Dolphin — full coverage to 50 feet, a long charge, and the longest confirmed cordless warranty. Magnetic charging and Click-Up retrieval keep it tidy. The Dolphin Liberty 400 covers smaller pools for less. Neither skims the surface.
Best for fine debris: Dolphin Quantum
Premium · Corded · Floor, walls & waterline
The Dolphin Quantum includes fine and ultra-fine filtration without an app premium — the pick for dusty or silty water. It cleans the waterline to 50 feet on a weekly timer, corded. You are paying for filtration, not gadgets. If cloudy water is your recurring problem, it is the smart-money Dolphin.
Best for above-ground pools: Dolphin E10
Budget · Corded · Floor cleaning
The Dolphin E10 is purpose-built for above-ground pools — a true floor-cleaning robot with its own filter, no pump hookup. It is the budget above-ground pick, while the Dolphin Nautilus CC is the small in-ground value option. For app scheduling, the Dolphin Sigma; for a dealer-line package, the Dolphin Explorer E70.
How to choose
Pick corded for set-and-forget reliability and no battery to age, or cordless (the Liberty line) to lose the cable. Then match coverage — floor-only, floor-and-wall, or full waterline — to what your pool actually needs, and step up to fine filtration only if dust is your real problem.
Frequently asked questions
Which Dolphin pool cleaner should I buy?
For most in-ground pools, the Dolphin Nautilus CC Plus. For leaves, the Dolphin Premier; for cordless, the Dolphin Liberty 600; for fine debris, the Dolphin Quantum; and for above-ground pools, the Dolphin E10.
What is the difference between Dolphin models?
They differ mainly by coverage (floor-only, floor-and-wall, or full waterline), power (corded or the cordless Liberty line), filtration (standard versus fine and ultra-fine kits), and extras like app scheduling. Match those to your pool rather than chasing the top model.
Are Dolphin pool cleaners reliable?
Dolphin, made by Maytronics, has the largest parts-and-service network in the category, which is a big reason the line stays fixable and dependable for years.
Do Dolphin cleaners come with an app?
Some do and many don't. Models like the Sigma and Liberty line add app scheduling, while value picks like the Nautilus CC Plus keep a simple weekly timer instead — which is part of what keeps them affordable.
Which Dolphin is best for above-ground pools?
The Dolphin E10 is purpose-built for above-ground pools — a true floor-cleaning robot with its own filter and no pump hookup.
