Owning a pool is a luxury, but keeping it clean has always been a chore. Manual brushing, vacuuming, and constant skimming eat into your free time — which is why robotic pool cleaners are booming. Among the leaders, Dolphin by Maytronics is known worldwide for premium, durable, and tech-forward robotic cleaners.
The new Dolphin Explorer E30 Wi-Fi (2025 model) is a serious upgrade for homeowners with inground pools up to 50 feet. It combines powerful suction, wall-climbing ability, a dedicated waterline scrub brush, and Wi-Fi smart control into a lightweight unit that takes over your pool maintenance with minimal effort.
- ALWAYS CONNECTED: With the Dolphin Explorer E30 robotic pool vacuum cleaner, schedule your pool cleanings from anywhere with always connected Wi-Fi.
- WATERLINE SCRUBBING: Dolphin’s powerful technology ensures a spotless waterline. As your robot constantly grips the pool walls, it guarantees a thorough cleaning.

Key Features of the Dolphin Explorer E30
1. Wi-Fi Smart Control
With the MyDolphin Plus app, you can:
- Schedule daily or weekly cleanings.
- Start/stop cycles from anywhere.
- Choose quick clean vs. deep clean modes.
This turns pool care into a “set it and forget it” routine.
2. Wall-Climbing + Waterline Scrubbing
Cheaper robots often only clean the pool floor. The E30 climbs walls and actively scrubs the waterline, where oils and debris tend to stick. That’s a big step toward a truly hands-off experience.
3. Advanced Scanning Navigation
Instead of random wandering, Dolphin’s smart sensors map your pool for optimized coverage. No wasted time or missed corners.
4. Dual Scrubbing Brushes
The active brushes spin faster than water flow, ensuring algae, dirt, and biofilm don’t just get pushed around — they’re scrubbed off surfaces.
5. Top-Load Filtration System
- Large basket filters catch leaves, sand, and fine debris.
- Easy to remove, rinse, and replace.
- Saves money compared to disposable filter bags.
6. 50 FT Swivel Cable
The anti-tangle swivel design means the robot can roam freely without knotting the cord — a common frustration with older cleaners.
7. Energy Efficient
At roughly 5 cents per cleaning hour, the Explorer E30 consumes far less power than running a booster pump for pressure cleaners.
Performance Review
Pool Floor Cleaning
The Explorer E30 easily sucks up sand, silt, and fine dirt. The scrubbing brushes prevent residue buildup.
Wall & Waterline Cleaning
It reliably climbs vertical walls and scrubs at the waterline — an area where most dirt and sunscreen oils accumulate.
Efficiency & Coverage
A full 2-hour cycle is usually enough for pools under 40 ft. Larger pools may require a second cycle. Navigation is precise, covering corners and stairs better than suction-side cleaners.
App Control
Scheduling cleanings from your phone makes maintenance nearly automatic. The Wi-Fi feature is a game-changer if you want flexibility (e.g., cleaning the pool before guests arrive while you’re away).
Pros & Cons
✅ Pros
- Cleans floor, walls, and waterline
- Wi-Fi app control for scheduling & remote start
- Large, easy-to-clean top-load filters
- Smart navigation avoids wasted time
- Tangle-free swivel cable
- Energy-efficient compared to pressure cleaners
- Lightweight (~16 lbs) for easy handling
❌ Cons
- Price is premium vs. entry-level robots
- 2-hour cycle may not fully clean extra-large pools in one pass
- App requires strong Wi-Fi near the pool area
- Doesn’t include remote control (app only)
