Differences Between Dolphin S100 vs Dolphin S200
Cleaning Coverage and Pool Compatibility
The Dolphin S100 is designed for in-ground pools up to 33 feet and focuses solely on floor cleaning. It does an excellent job on flat surfaces and performs reliably in small to mid-sized pools with minimal slopes. However, it does not clean walls or waterline, which limits its usefulness in more complex pools or those prone to vertical algae growth.
The Dolphin S200 supports in-ground pools up to 50 feet and provides complete coverage of the floor, walls, and waterline. It climbs surfaces efficiently and delivers a more comprehensive clean, eliminating the need for manual brushing in upper sections.
Winner: Dolphin S200
With full-surface cleaning including vertical walls and waterline, the S200 is clearly the superior option for complete pool hygiene.
Both the S100 and S200 utilize CleverClean™ Technology, which maps the pool floor and optimizes cleaning routes to avoid random or redundant passes. The navigation system helps each robot complete its cleaning cycle within a 2-hour timeframe.
However, the S200 enhances this system with PowerStream™ mobility, which stabilizes the cleaner on vertical surfaces and improves directional control. PowerStream jets allow it to adjust pressure and maintain adhesion when climbing, providing better wall and waterline tracking.
Winner: Dolphin S200
Its enhanced mobility system allows for superior wall climbing, tighter path control, and better efficiency during vertical cleaning.
Scrubbing Power and Brush Configuration
The S100 is equipped with a single active front brush that rotates at a higher speed to scrub away dirt, algae, and grime on the pool floor. This brush is effective for flat, horizontal cleaning but doesn’t offer complete surface engagement due to the absence of wall cleaning.
The S200 includes a single active front brush and a passive rear brush, giving it dual contact points during operation. This results in more balanced scrubbing action and smoother transitions from floor to walls and up to the waterline. It also means better contact and coverage, especially in curved or uneven pool shapes.
Winner: Dolphin S200
With dual-brush action, the S200 delivers more effective debris agitation across multiple surfaces and ensures cleaner results with fewer missed spots.
Filtration Capacity and Debris Capture
The S100 comes with a top-loading fine filter cartridge, ideal for capturing common debris such as small leaves, twigs, and sand. While effective for most routine cleaning, it lacks the multi-layer filtration system that’s increasingly valuable for trapping finer particles like dust, algae spores, and pollen.
The S200 features a multi-layer filtration basket with both fine and ultra-fine filtration, allowing it to simultaneously trap large debris and microscopic contaminants. Its capacity is larger as well, reducing the frequency of rinsing and enhancing water clarity after each cycle.
Winner: Dolphin S200
Its multi-layer filter ensures higher performance across varied debris sizes, leading to a cleaner pool and more efficient maintenance.
Mobility and Climbing Capability
The S100 uses a standard wheel-based system, which is smooth and reliable for flat surfaces but has limited ability to handle elevation or slippery tiles. It’s not designed to climb walls, and its wheel configuration lacks directional flexibility on vertical planes.
The S200 combines wheels with PowerStream™ lateral jets, enhancing grip and balance during wall climbing. It scales vertical surfaces confidently and maintains strong surface contact across textured or slippery finishes.
Winner: Dolphin S200
Its PowerStream-enhanced mobility enables superior surface climbing and directional control on a variety of pool surfaces.
Cable Length and Tangle Resistance
The S100 features a 40-foot floating cable without a swivel, which is adequate for smaller pools but may tangle over time, especially during frequent use or when repositioning the robot manually.
The S200 comes with a 60-foot swivel cable, reducing drag and preventing twisting as it navigates longer and deeper pools. This is particularly helpful for consistent coverage without pausing to untangle cords.
Winner: Dolphin S200
Its longer, swivel-enabled cable ensures tangle-free performance and accommodates larger pool dimensions.
Scheduling and Automation
The S100 does not support a weekly scheduler. Each cleaning cycle must be manually started through its power supply, which may be a drawback for users looking for automatic daily or routine cleaning.
The S200 includes a built-in weekly scheduler, enabling users to pre-program cleaning sessions for daily, every other day, or every third day. This significantly enhances automation and reduces the burden of manual starts.
Winner: Dolphin S200
With scheduling built-in, the S200 is a far more autonomous and hands-free solution for busy pool owners.
User Experience and Maintenance
At 14.6 lbs, the S100 is one of the lightest robotic pool cleaners in its class. It’s easy to lift, remove from the pool, and rinse off after cleaning. Its simple design caters to users who value minimal setup and quick maintenance.
The S200 weighs slightly more at 16.5 lbs, but the ergonomic handle and top-load filter make handling and maintenance equally easy. Despite its added power and functionality, it remains remarkably user-friendly.
Winner: Tie
Both cleaners offer great ease of use, though the S100 may appeal more to users prioritizing ultra-lightweight handling.

Conclusion
Choose Dolphin S100 if you own a small to medium in-ground pool and want a lightweight, no-frills robotic cleaner that offers solid floor cleaning at an affordable price. It’s a smart choice for first-time robotic pool cleaner buyers who want dependable performance without extra features.
Choose Dolphin S200 if you’re seeking a more powerful and autonomous robotic cleaner that can scrub walls, climb to the waterline, and trap ultra-fine debris. Its PowerStream mobility, multi-layer filtration, and built-in scheduling make it a significantly more advanced and comprehensive cleaning solution.
Overall Winner: Dolphin S200
With extended surface coverage, better scrubbing performance, superior filtration, and built-in automation, the Dolphin S200 stands out as the more capable, full-featured robotic pool cleaner, offering a better long-term investment for most pool owners.
