The full picture
The Explorer E70 is the top of Maytronics' Explorer line: floor, wall, and waterline coverage for in-ground pools up to 50 feet, selectable 1.5/2/2.5-hour cycles, MyDolphin Plus app control, a Pick-Up Mode for retrieval, a temperature sensor, multi-layer filtration with an ultra-fine kit included, and a storage caddy. Sold largely through pool dealers, it pairs premium cleaning with in-person service. It's the Dolphin to compare against the Polaris VRX iQ+ when dealer support matters as much as the hardware.

The in-depth review
The Explorer E70 is the premium, dealer-line Dolphin — the one you buy through a pool store rather than a big-box site, and the one that arrives as a complete package with a caddy in the box.
The complete package
Its pitch is flexibility and completeness. Selectable cycle lengths let you tune how long and hard it works, and the included multi-layer plus ultra-fine filtration handles everything from leaves to fine dust. A temperature sensor and Pick-Up Mode round it out, and it cleans floor, walls, and waterline on pools up to 50 feet. The caddy and the dealer relationship are part of what you're paying for.
The trade-offs
It's corded and it's a heavier premium unit, and dealer-line pricing sits at the top of the Dolphin range. You're buying service and a full kit, not portability.

Best dealer-serviced premium
A dealer-backed premium corded robot with app control, a huge filter canister, and Polaris' decades-deep service network.
Beatbot
Beatbot AquaSense 2 Pro
Best surface-skimming value
The Beatbot most people should actually compare: surface skimming plus full underwater coverage, below the Ultra's price.
Dolphin (Maytronics)
Dolphin Nautilus CC Plus
Best overall for most in-ground pools
The default recommendation for in-ground pools up to 33 feet: reliable floor-and-wall cleaning, easy top-load filters, and Maytronics' service network behind it.
Dolphin (Maytronics)
Dolphin Premier
Best for leaves & mixed debris
The corded Dolphin for messy pools: interchangeable filter media — including an oversized leaf bag — make it the debris-handling specialist.
Frequently asked questions
Is the Dolphin Explorer E70 cordless or corded?
The Dolphin Explorer E70 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 Explorer E70 clean?
The Dolphin Explorer E70 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 Explorer E70 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 Explorer E70 have app control?
Yes — the Dolphin Explorer E70 pairs with a mobile app, and it supports scheduling.
What filtration does the Dolphin Explorer E70 use?
It filters debris through a multi-layer and ultra-fine kit. Rinse it after each cycle so suction and pickup stay strong.
What warranty does the Dolphin Explorer E70 come with?
It comes with a 3-year limited manufacturer warranty (confirm current terms at purchase).
