The competition between the Dolphin Liberty 300 vs the Aiper Scuba S1 Pro represents two distinct philosophies in cordless robotic pool cleaner design. While both models offer tangle-free operation and smart navigation, they diverge in suction power, filtration sophistication, runtime, app functionality, and cleaning flexibility.
This comprehensive comparison evaluates every core metric to determine which cleaner delivers the better value, convenience, and cleaning performance for modern in-ground and above-ground pools.

Differences Between Dolphin Liberty 300 vs Aiper Scuba S1 Pro
Below is a summary of the specifications:
Design Comparison
The Dolphin Liberty 300 is tailored for small to medium pools with a lightweight, compact design and innovative Click-Up™ retrieval system, which allows users to lift the robot using a magnetic pole signal. It is simple to deploy and remove, especially for users with limited physical mobility.
In contrast, the Aiper Scuba S1 Pro is larger, more robust, and designed to handle pools up to 2,150 sq ft, making it suitable for large in-ground pools and more complex layouts. Its design is defined by a quad-motor platform that improves propulsion, wall-climbing stability, and debris suction. While it does not include Click-Up™, the Scuba S1 Pro uses auto-parking, positioning itself near the wall when a cycle ends for easier manual retrieval.
Both models meet the IPX8 waterproof rating, ensuring safe underwater operation and long-term reliability. However, only the Aiper includes a 5-liter debris chamber, which extends time between cleanouts significantly.
Winner: Aiper Scuba S1 Pro
Built for larger pools with more powerful propulsion and higher debris capacity, making it the more versatile cleaner by design.
Cleaning Performance Comparison
When comparing cleaning performance, the Scuba S1 Pro clearly dominates in coverage, runtime, and debris handling. It offers full-floor, wall, and waterline cleaning, powered by a PVC roller brush and 4,200 GPH suction. Its cleaning cycle lasts up to 180 minutes, ensuring complete coverage even in expansive pools.
The Dolphin Liberty 300 performs well for its size, with 90-minute cleaning cycles and floor and wall coverage only. It lacks a dedicated waterline mode, which limits its ability to clean the critical scum layer along the pool’s edge.
The Liberty 300’s suction rate is unlisted, but based on its battery capacity and runtime, it is likely around 3,000 GPH, which is sufficient for leaves, sand, and light algae but may struggle with dense or compacted debris.
Filtration also reveals a stark contrast. The Scuba S1 Pro includes a dual-layer filtration system combining a 180 μm mesh pre-filter with a 3 μm fine mesh, capable of trapping large leaves and microscopic particles in one pass. The Liberty 300 relies on a fine cartridge filter, which clogs more quickly and must be emptied more frequently.
Winner: Aiper Scuba S1 Pro
Superior suction, full-surface coverage, and advanced filtration make it the better performer across all pool types.
Feature Comparison
The Dolphin Liberty 300 is limited in smart features. It offers Bluetooth-based setup, mainly for firmware installation, with no app-based control, no scheduling options, and no real-time customization. Cleaning modes are fixed and must be initiated manually.
The Aiper Scuba S1 Pro, in contrast, provides complete app integration via Wi-Fi and Bluetooth using the Aiper App. It supports Auto, Eco, Floor-only, Wall-only, and Waterline modes, letting users fine-tune cleaning tasks to suit daily, weekly, or seasonal needs. OTA updates also keep the software current and responsive to future improvements.
Charging time is another deciding factor. While the Liberty 300 uses inductive charging, which is sleek and safe, it takes up to 6 hours to recharge. The Scuba S1 Pro uses standard contact charging and completes a full charge in just 3–4 hours, enabling more frequent operation.
The Scuba S1 Pro also includes LED status indicators, auto-parking, and quad independent brushless motors, providing redundancy, smoother movement, and higher torque for scaling slippery surfaces.
Winner: Aiper Scuba S1 Pro
Richer feature set, full app support, flexible cleaning modes, faster charging, and better control tools make it the clear winner in functionality.
