In the competitive world of cordless robotic pool cleaners, the Aiper Scuba S1 vs Dolphin Liberty 200 stand out as two of the most advanced and reliable options for residential pools. Both models eliminate cords, offer wall-climbing capabilities, and deliver smart navigation systems — but they differ in runtime, filtration, suction performance, and user experience.
This side-by-side comparison breaks down everything pool owners need to know to determine which of these cordless units offers the best combination of power, precision, and long-term value.

Differences Between Aiper Scuba S1 vs Dolphin Liberty 200
Design Comparison
The Aiper Scuba S1 and Dolphin Liberty 200 are both fully cordless, making them easy to deploy and retrieve without cable management hassles. However, they are designed for different scales of use. The Scuba S1 supports pools up to 1,600 sq ft, while the Liberty 200 is limited to ~860 sq ft, or pools up to 8 x 4 meters.
Both cleaners are similar in weight — 17 lb for the Scuba S1 and 17.9 lb for the Liberty 200. Despite its lighter body, the Scuba S1 packs a larger filtration basket and longer runtime. The Dolphin Liberty 200 includes the Click-Up™ system, which allows users to raise the cleaner by waving the retrieval pole nearby — a convenience the Scuba S1 lacks, though it does feature auto-parking for easy edge-side pickup.
In terms of design efficiency and capacity, the Aiper Scuba S1 is optimized for a broader range of pool types and sizes, making it the more flexible choice.
Winner: Aiper Scuba S1
With larger pool compatibility, easier app integration, and greater runtime efficiency, the Scuba S1 offers superior design versatility.
Cleaning Performance Comparison
The Scuba S1 covers floor, wall, and waterline cleaning, while the Dolphin Liberty 200 handles floor and wall cleaning but lacks waterline coverage. This gives Aiper a distinct advantage for complete pool hygiene, especially in regions where scum lines and algae build-up frequently at the waterline.
Suction performance is clearly in favor of the Scuba S1, offering 4,200 gallons per hour, driven by dual drive motors and a high-flow brushless filtration system. The Liberty 200’s suction rating isn’t officially published, but based on performance class and runtime, it’s estimated around 3,000 GPH — adequate for small pools, but less effective in high-debris conditions.
The Scuba S1 features an active PVC roller brush that spins rapidly to dislodge stuck-on debris. The Liberty 200 also has an active brush, but its smaller cleaning path and reduced suction limit its debris lift capacity compared to the Aiper unit.
Both models use smart navigation systems. The Scuba S1 uses WavePath™ 2.0, which creates optimized zig-zag cleaning routes. The Liberty 200 relies on CleverClean™ scanning, enhanced by a gyroscope for spatial orientation. While both avoid redundant paths, Aiper’s pathing offers broader, more consistent lane coverage.
Winner: Aiper Scuba S1
With stronger suction, longer runtime, waterline coverage, and larger area support, it delivers superior cleaning performance.
Feature Comparison
The Aiper Scuba S1 features a more advanced feature set for tech-savvy users. It offers app control via the Aiper App, allowing users to switch cleaning modes, monitor battery status, and receive notifications. It supports four cleaning modes: Auto, Eco, Floor-only, and Wall-only. This allows owners to customize cleaning cycles based on daily usage or seasonal needs.
In contrast, the Dolphin Liberty 200 does not support full app control. It connects via Bluetooth for basic pairing, but users cannot change modes or monitor performance via a smartphone. It includes a Click-Up™ retrieval system, which responds to a proximity sensor from the retrieval pole — an innovative but niche feature.
Charging mechanisms differ as well. The Scuba S1 uses a magnetic pogo-pin-style charger and takes about 3–4 hours to recharge. The Liberty 200 uses an inductive charging dock, which is modern and waterproof-safe, but charging takes up to 6 hours to reach full capacity.
Both units feature auto-parking, where they stop near the edge of the pool when the cycle ends, allowing easier retrieval without diving.
Winner: Aiper Scuba S1
With advanced app integration, customizable modes, faster charging, and OTA update potential, it leads in smart features and user flexibility.
