The Dolphin Explorer E50 is part of Maytronics’ premium robotic cleaner lineup, sold through select pool retailers. Designed for in-ground pool owners who want a combination of power, smart navigation, and easy maintenance, the E50 promises to clean floors, walls, and the waterline while giving you more control through app connectivity.
We tested the Explorer E50 for an entire swim season to evaluate its cleaning performance, ease of use, durability, and overall value for the price.
First Impressions
Out of the box, the E50 has a sleek, modern look with a sturdy build. It’s noticeably more robust than entry-level Dolphin models and comes with a tangle-resistant swivel cable, an advanced power supply, and a large top-access filter basket. The included caddy makes transport and storage much easier, which is a nice touch at this price point.
Setup is simple—connect the 60-foot swivel cable, plug in the power supply, and choose a cleaning mode. The MyDolphin Plus app allows for remote control, cycle selection, and scheduling, adding a layer of convenience.
Key Features
- Coverage: Floors, walls, and waterline cleaning.
- Navigation: CleverClean scanning technology with advanced sensors for efficient coverage.
- Filtration: Extra-large, top-loading basket with fine and ultra-fine filter options.
- Cycle Options: Standard (2 hours) and enhanced cleaning modes.
- Cable: 60-foot tangle-free swivel cable.
- App Control: MyDolphin Plus app for scheduling and remote operation.
- Brushes: Dual active brushes for deep scrubbing.
Performance Testing
Over the summer, we ran the E50 multiple times per week in a 20’ x 40’ in-ground pool with both light daily debris and heavier post-storm cleanups.
Floor Cleaning
The E50 excelled at picking up fine dirt, sand, and organic debris. Its active brushes loosened stubborn grime before the suction pulled it into the filter basket. Coverage was consistent, and most runs left the floor spotless without a second cycle.
Wall and Waterline Cleaning
This is one of the E50’s strongest features. It climbed walls smoothly and scrubbed right at the waterline, removing oily residue and dirt that can be tough to reach manually. Unlike some mid-tier models, it rarely failed to make it all the way up the wall.
Navigation and Coverage
The CleverClean system allowed for efficient movement and minimal overlap. Even in a freeform pool with benches and steps, it navigated around obstacles well. While a second pass helps after extreme debris loads, a single cycle was usually enough for standard cleaning.
Debris Handling
The oversized filter basket was a standout feature—large enough to handle a day’s worth of leaves and dirt without clogging. The basket’s dual filter system allows you to choose between fine and ultra-fine screens depending on the type of debris you’re dealing with.
Ease of Maintenance
Cleaning the filter basket is simple—lift it out from the top, dump debris, and rinse with a hose. The rigid design makes it easy to handle, and because it’s top-loading, you never need to flip the robot over.
App Control and Scheduling
The MyDolphin Plus app gives you full control over cleaning cycles and lets you set a schedule so the E50 runs automatically. You can also manually direct the cleaner for spot cleaning, which is handy if you see a problem area.
Energy Efficiency
Like other Dolphin robots, the E50 operates on low voltage, using far less energy than suction or pressure cleaners. Even with multiple weekly cleanings, it has minimal impact on the electric bill.
Durability Over Time
After a season of heavy use, the E50’s brushes, tracks, and motor remained in excellent condition. The cable swivel prevented significant tangling, and the housing showed no signs of water intrusion or wear beyond light scuffing.
