Differences Between Dolphin S200 vs Dolphin Liberty 200
Design, Handling, and Portability
The Dolphin S200 features a classic plug-in design with a 60-foot swivel cable that prevents tangling during cleaning sessions. Its streamlined profile and 16.5-pound weight make it easy to transport and deploy, especially for routine use in medium to large pools. The top-handle placement ensures smooth retrieval from the water, and the unit balances well for vertical storage.
In contrast, the Dolphin Liberty 200 is built around cordless convenience. It weighs slightly more at 18.5 pounds, but this includes its internal battery pack. It lacks a cable entirely, operating via a rechargeable lithium-ion battery and charging through a magnetic snap-in port that attaches easily when out of the water. The absence of a cable removes obstacles during operation, improving maneuverability and eliminating drag.
Winner: Dolphin Liberty 200
For users seeking cordless freedom and easier maneuvering with no cable management, the Liberty 200 leads in portability and minimalist design.
Power Source and Runtime
The S200 connects directly to an external power supply, providing consistent energy throughout a 2-hour cleaning cycle. This allows the cleaner to run at full performance from start to finish, regardless of pool conditions or surface types.
The Liberty 200 relies on an internal rechargeable battery that offers up to 90 minutes of cleaning on a full charge. While this is sufficient for small to mid-sized pools, runtime limitations can impact performance in larger environments. The cleaner may not always finish an entire cycle if used in pools near its maximum size capacity.
Winner: Dolphin S200
With unlimited runtime and uninterrupted power, the S200 remains the superior choice for extended or high-debris sessions.
Coverage and Pool Size Compatibility
The Dolphin S200 is designed for in-ground pools up to 50 feet, offering complete coverage of the floor, walls, and waterline. It effectively climbs walls and transitions seamlessly from floor to vertical surfaces using its active brush rotation and smart pathing.
The Liberty 200, while cordless and agile, is intended for pools up to 32 feet and only cleans the floor and walls. It lacks waterline cleaning capability, which may require manual touch-ups around the top edge of the pool after robotic cycles are complete.
Winner: Dolphin S200
With broader pool compatibility and full waterline reach, the S200 wins in cleaning range and surface coverage.
Both units are equipped with CleverClean™ Smart Navigation, which scans the pool and determines a logical cleaning path to reduce overlap and maximize efficiency. This system adapts to different pool shapes—rectangular, round, kidney-shaped—and minimizes missed spots.
However, the Liberty 200, being battery-powered, is designed to conserve energy and prioritize essential coverage. As a result, its navigation logic is slightly more conservative than the S200, which has full access to continuous power and can afford more aggressive routing.
Winner: Dolphin S200
With unrestricted runtime and full-cycle optimization, the S200 delivers more thorough and confident coverage over larger areas.
Scrubbing Performance and Debris Agitation
The S200 features dual active brushes, located at the front and rear of the unit. These rotate independently of the robot’s drive system, allowing the brushes to scrub algae, sediment, and debris aggressively from every angle, including stubborn spots on tile or vinyl surfaces.
The Liberty 200 uses a single active brush, positioned at the front, which is effective for general debris but less efficient when it comes to tackling persistent algae or deeply embedded dirt. Wall scrubbing is adequate, but the lack of a secondary brush reduces the overall friction and contact power.
Winner: Dolphin S200
Its dual-brush system provides better cleaning depth and broader agitation across all surfaces.
Filtration System and Debris Handling
Both the S200 and Liberty 200 feature top-load filter baskets, which are easy to access and rinse. The S200 comes with both fine and ultra-fine filters, allowing users to adjust based on seasonal needs—fine for leaves and larger debris, ultra-fine for pollen, sand, and dust.
The Liberty 200 includes a single fine filter basket, optimized for general debris but not designed for ultra-fine particle capture. This makes it ideal for routine maintenance but slightly less capable in capturing micro-contaminants or dust during heavy-use seasons.
Winner: Dolphin S200
With customizable filtration and a dual-layer system, the S200 handles a wider range of debris more effectively.
Cord vs Cordless: Usability Differences
The Dolphin Liberty 200’s cordless design eliminates one of the most common complaints about robotic pool cleaners—cable tangling. Without a power cord to manage, it glides effortlessly across the pool, avoids entanglement, and reduces setup time.
However, this convenience comes at the cost of limited runtime, potential incomplete cycles in larger pools, and the need to monitor battery status.
The S200, despite using a cable, includes a swivel mechanism to prevent tangling and delivers uninterrupted power throughout its cleaning cycle.
Winner: Dolphin Liberty 200
For ease of use, simplicity, and true plug-and-play operation, the cordless Liberty 200 wins in convenience.
Smart Features and Automation
The S200 includes a weekly scheduler, allowing users to program cleaning cycles in advance. It can be set to clean daily, every other day, or every third day—all without further input. It does not include smartphone integration but offers complete automation through its onboard control unit.
The Liberty 200, by contrast, does not include any scheduling features. It must be manually turned on before each cleaning cycle. There is no remote control, no timer function, and no app connectivity.
Winner: Dolphin S200
With scheduling and a more robust control unit, the S200 provides greater automation and long-term user independence.
