The Dolphin E10 vs Dolphin S100 are two of the most affordable robotic pool cleaners offered by Maytronics, built to simplify pool maintenance for residential owners. Both are tailored for small in-ground and above-ground pools, making them ideal for users looking to automate their cleaning process without investing in higher-end models.
While they share many similarities in size and performance, they differ in filtration, climbing ability, and coverage. In this detailed comparison, we analyze every major aspect to determine which model offers better long-term value for your pool.

Differences Between Dolphin E10 vs Dolphin S100
Design Comparison
The Dolphin E10 and Dolphin S100 are both designed for small residential pools, but their intended environments differ slightly. The E10 is built primarily for above-ground pools, although it can also be used in smaller in-ground pools with flat bottoms. The S100, on the other hand, is intended for in-ground pools up to 33 feet, with additional capability to climb walls—a feature the E10 lacks.
The E10 includes a 40-foot cable, which is sufficient for most round or oval above-ground pools, while the S100 comes with a 50-foot cable to ensure it can reach both ends of a standard rectangular in-ground pool. Neither model includes a swivel mechanism, so occasional cable tangling is possible, especially in non-symmetrical pools.
Both units weigh under 15 pounds, with the E10 at 13.8 lbs and the S100 at 14.6 lbs. Their compact design makes them easy to lift out of the water, store, and maintain. They also share the same ergonomic carry handle and easy-access filter lid on the top.
Winner: Dolphin S100
With its longer cable and support for wall cleaning in in-ground pools, the S100 is more versatile and better suited for varied pool shapes and depths.
Cleaning Performance Comparison
The Dolphin E10 features a single active brush at the front, which rotates faster than the robot’s movement speed to scrub dirt, algae, and grime from the pool floor. It is built to clean only the floor, and does not climb pool walls. This makes it ideal for flat-bottom pools, but less effective for pools with steps, coves, or vertical surfaces that accumulate debris.
The Dolphin S100 also uses a single active brush, but includes wall climbing capabilities, enabling it to clean both the pool floor and lower wall areas. While it doesn’t reach the waterline, the additional vertical cleaning adds to its effectiveness, particularly in pools where dust and debris settle on walls as well as the floor.
Both units offer a suction rate of 4000 gallons per hour, providing strong vacuum power to collect debris efficiently. The E10 runs a fixed 1.5-hour cleaning cycle, while the S100 operates for 2 hours, allowing for more comprehensive coverage.
Filtration is another key difference. The E10 comes with a fine top-load basket, designed for leaves, insects, and larger debris, but it does not filter finer particles such as sand or pollen very effectively. The S100 includes both fine and ultra-fine filters, enabling it to trap significantly smaller debris and maintain cleaner water.
Winner: Dolphin S100
With wall cleaning, longer runtime, and dual-stage filtration, the S100 offers superior cleaning performance, especially in in-ground pools with varied surfaces.
Feature Comparison
Neither the Dolphin E10 nor the Dolphin S100 includes smart features, Wi-Fi control, or a mobile app. These are basic, entry-level models built for users who want simple, plug-and-play operation without any digital configuration. Both cleaners are controlled entirely through a physical power supply that toggles the unit on and off.
That said, the S100 offers slightly more functional flexibility with its extended cycle time and advanced filtration. Maintenance on both models is straightforward, thanks to top-access filter compartments that make it easy to rinse out debris. However, users with seasonal or dusty pool environments will appreciate the ultra-fine filtration of the S100, which helps maintain better water clarity with fewer passes.
The S100’s ability to clean both floors and walls also adds functional value, making it suitable for users who want more than just floor-level cleaning. Although it lacks a waterline scrub, the vertical reach adds significantly to debris removal compared to the E10’s flat-only coverage.
Winner: Dolphin S100
While neither model offers smart functionality, the S100’s longer cycle, superior filtration, and wall-cleaning ability make it more feature-complete.

Conclusion
Choose Dolphin E10 if you have a round or oval above-ground pool and want a lightweight, budget-friendly robotic cleaner for simple floor cleaning. It’s best for users who prioritize ease of use and fast cycle time over advanced filtration or full pool coverage.
Choose Dolphin S100 if you need a cleaner for an in-ground pool, or if you want the added benefit of wall cleaning and finer filtration. It’s better suited for users looking for deeper cleaning without jumping into premium pricing tiers.
Overall Winner: Dolphin S100
With enhanced coverage, improved filtration, and better adaptability for in-ground pools, the Dolphin S100 delivers more value and cleaning performance across a broader range of pool types. For homeowners seeking better water clarity and vertical cleaning capability in a compact, user-friendly format, the S100 is the superior choice.
