Quick verdict
If leaves and mixed debris are your pool's defining problem, this beats flashier robots. The leaf-bag option alone justifies it for tree-heavy yards.
Ideal for
- Pools under trees — the oversized leaf bag is the killer feature
- Mixed debris loads (leaves plus fine dirt)
- Owners who want proven corded reliability with a 3-year warranty
Not ideal for
- Cordless convenience seekers
- App-driven owners (no app on this model)
- Surface-debris problems
The full picture
The Premier's superpower is filter flexibility. Where most robots give you one basket, the Premier swaps between multi-layer media, a fine filter kit, and an oversized leaf bag — which is exactly what a pool under trees needs in autumn and a pool full of silt needs in spring. Maytronics lists floor, wall, and waterline coverage for pools up to about 50 feet, a 3-hour cycle, weekly timer, anti-tangle swivel, and a 3-year warranty. No app, no battery, no surface skimming — just a proven corded platform that handles more kinds of debris than almost anything else. Owner feedback consistently ranks it among the best leaf-handling robots ever made.

The in-depth review
The Premier is the Dolphin for messy pools. Its whole identity is filtration flexibility — you swap between fine media and an oversized leaf bag depending on what's falling into the water — which makes it the debris specialist in the corded lineup.
The leaf-bag advantage
Where the Premier separates itself is the interchangeable filter media. Drop in the oversized leaf bag and it swallows the volume a pool under oaks or palms throws at it without clogging every cycle; swap to the fine kit when the problem shifts to dirt and dust. It covers floor, walls, and the waterline on pools up to 50 feet, and an anti-tangle swivel keeps the cable behaved.
The trade-offs
It's corded, so cable management is still part of the deal, and there's no app — this is old-school reliability, not smart-home tech. At luxury pricing you're paying for the cleaning system, not for gadgetry, which won't be for everyone.

Frequently asked questions
Is the Dolphin Premier cordless or corded?
The Dolphin Premier is corded — it runs on continuous mains power through a floating cable, so there is no battery to recharge between cycles.
What does the Dolphin Premier clean?
The Dolphin Premier is rated to clean the floor, walls and waterline. That includes the waterline, where sunscreen and body oils build into a greasy ring. It is an underwater cleaner, so it does not skim floating debris off the surface.
What size pool is the Dolphin Premier designed for?
It is rated for pools up to 50 feet. On a longer pool it covers less ground per cycle and can miss spots, so size up if your pool runs past that.
Does the Dolphin Premier have app control?
No — the Dolphin Premier runs from on-unit controls rather than a mobile app, though it does include a weekly timer.
What filtration does the Dolphin Premier use?
It filters debris through a multi-layer media, fine filter kit, oversized leaf bag. Rinse it after each cycle so suction and pickup stay strong.
What warranty does the Dolphin Premier come with?
It comes with a 3-year limited manufacturer warranty (confirm current terms at purchase).
