The competition between the Aiper Scuba S1 vs Dolphin Liberty 300 brings to light two of the most advanced cordless robotic pool cleaners for residential pools. Both machines are designed for seamless cable-free operation, comprehensive surface coverage, and intelligent navigation. However, important differences in runtime, app connectivity, cleaning coverage, suction power, and filtration depth separate these contenders.
This detailed comparison will dissect every specification to determine which cleaner offers the best overall value, efficiency, and cleaning performance for your in-ground or above-ground pool.

Differences Between Aiper Scuba S1 vs Dolphin Liberty 300
Below is a summary of the specifications:
Design Comparison
The Aiper Scuba S1 and Dolphin Liberty 300 are both streamlined for cordless, full-pool operation. However, the Aiper Scuba S1 is better optimized for medium-to-large pool sizes up to 1,600 sq ft, while the Dolphin Liberty 300 is rated for pools under 968 sq ft. This limits Liberty 300’s scope primarily to small residential pools or spas.
In terms of weight, both are evenly matched at approximately 17 to 17.9 lb, making them easy to lift in and out of the water. The Scuba S1 features auto-parking, positioning itself near the pool wall when cleaning ends, while the Liberty 300 features the Click-Up™ retrieval system, which lets users lift the robot using a magnetic pole trigger when the robot is signaled.
Although both have premium waterproofing and top-loading filter compartments, the Scuba S1’s larger body accommodates a 3.5-liter basket and longer-lasting motor system. Its external design focuses on streamlined propulsion and wall-gripping mobility, while the Liberty 300 favors compact design and retrieval convenience.
Winner: Aiper Scuba S1
Larger pool compatibility, more powerful architecture, and a refined retrieval system via auto-parking make it a more versatile design overall.
Cleaning Performance Comparison
Both the Aiper Scuba S1 and Dolphin Liberty 300 claim floor, wall, and waterline cleaning capabilities. However, differences in runtime, brush configuration, suction strength, and debris capacity result in unequal real-world performance.
The Scuba S1 offers up to 180 minutes of cleaning time thanks to its 7,800 mAh lithium-ion battery, more than double the 90-minute runtime of the Dolphin Liberty 300. This gives the Scuba S1 the ability to complete thorough cleans in medium-to-large pools without requiring multiple charges.
Suction power favors the Aiper Scuba S1, which provides 4,200 GPH, capable of removing debris ranging from leaves to fine sediment. The Liberty 300’s suction rate is unpublished, but based on Dolphin’s power class and runtime, it typically delivers around 3,000 GPH, which may struggle with heavier or more frequent contamination.
Both models include active brushes. The Scuba S1’s PVC roller brush rotates actively beneath the chassis and agitates debris along all surfaces. The Liberty 300 features a front-mounted active brush, which provides strong forward scrubbing but does not span the full width of the cleaner, limiting its contact path.
Each robot supports high-efficiency navigation. The Scuba S1 uses WavePath™ 2.0, optimizing its movement in smart zig-zag patterns. The Liberty 300 uses CleverClean™, enhanced by a gyroscope for wall-following precision. While both navigation systems are intelligent, Aiper’s WavePath™ offers superior geometric consistency, especially in rectangular and lap pools.
Winner: Aiper Scuba S1
Superior runtime, suction capacity, and comprehensive brush coverage give it a notable advantage in cleaning performance.
Feature Comparison
The Scuba S1 offers full app control via the Aiper App, supporting mode switching, battery status, firmware upgrades, and cleaning cycle selection. Cleaning modes include Auto, Eco, Floor-only, and Wall-only, giving users full flexibility to tailor operations based on time and needs.
The Liberty 300 lacks app control. It uses Bluetooth pairing for firmware setup only, with no real-time customization or cycle programming. Mode selection is manual and preset, and no Eco mode or targeted surface options are available.
Filtration is another area where the Scuba S1 pulls ahead. It includes a dual-layer system combining a 180 μm basket for large debris and a 3 μm ultra-fine mesh for micro-particles. The Liberty 300 has a fine cartridge filter but lacks dual-layer separation, making it more prone to clogging in high-debris environments.
Charging differences are significant. The Scuba S1 charges in 3 to 4 hours, while the Liberty 300 uses inductive charging, which is safer and sleeker but slower, requiring up to 6 hours to recharge fully. For users needing daily cleanings, Aiper’s faster recharge is a crucial advantage.
Winner: Aiper Scuba S1
It delivers more control, smarter features, better filtration, and shorter charging times, making it the more advanced system for demanding users.
