Dolphin Explorer E50 review

Best Wi-Fi Dolphin for waterline

8.6/10Editorial score · Updated 2026-07-03

A Wi-Fi Dolphin that adds waterline cleaning and app scheduling to the proven Nautilus platform, with an extra-large filter basket.

Quick verdict

The natural upgrade from a Nautilus CC Plus: you add waterline cleaning, app control, and a bigger basket without leaving the Dolphin comfort zone.

Ideal for

  • In-ground pools up to 50 ft
  • Owners who want waterline cleaning plus app scheduling
  • Debris loads that fill smaller baskets fast

Not ideal for

  • Cordless seekers
  • Heavy-leaf pools (no leaf bag like the Premier)
  • Budget buyers

The full picture

The Explorer E50 is Maytronics' step up from the Nautilus CC line: floor, wall, and waterline coverage for in-ground pools up to 50 feet, a 2-hour cycle, MyDolphin Plus app control with a weekly timer, an anti-tangle swivel, and an extra-large top-load fine-filtration basket that means fewer mid-clean empties. It's the Dolphin to compare when you want waterline scrubbing and app scheduling but don't need the Premier's swappable leaf bag or the Sigma's ultra-fine filtration.

The in-depth review

The Explorer E50 is the natural upgrade path from a Nautilus CC Plus. It keeps the proven Dolphin platform and adds the three things owners most often wish the Nautilus had: waterline cleaning, app scheduling, and a bigger filter basket.

What the upgrade buys you

On top of the familiar floor-and-wall cleaning, the E50 scrubs the waterline and adds MyDolphin Plus app control with a weekly timer. The extra-large top-load basket means fewer mid-clean empties on a debris-heavy pool, and it covers pools up to 50 feet. The anti-tangle swivel and Maytronics service network carry over.

The trade-offs

It's corded, so cable management stays. Unlike the Premier, there's no swappable oversized leaf bag, so a very leafy pool is still better served by that model. And it sits at premium pricing.

Frequently asked questions

Is the Dolphin Explorer E50 cordless or corded?

The Dolphin Explorer E50 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 E50 clean?

The Dolphin Explorer E50 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 E50 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 E50 have app control?

Yes — the Dolphin Explorer E50 pairs with a mobile app, and it supports scheduling.

What filtration does the Dolphin Explorer E50 use?

It filters debris through an extra-large top-load fine basket. Rinse it after each cycle so suction and pickup stay strong.

What warranty does the Dolphin Explorer E50 come with?

It comes with a 3-year limited manufacturer warranty (confirm current terms at purchase).
