Score: 80/100
Aiper Surfer S2
Score: 70/100Rankings

The Pool Blaster CX-300 is a cordless robotic cleaner with strong suction and wall-climbing ability, ideal for pools up to 150 m². Its heavier weight and occasional runtime reductions are notable trade-offs. Best for homeowners who prioritize cordless convenience and robust cleaning over ultra-light portability.

The Aiper Surfer S2 combines solar charging with app-based scheduling, delivering up to 35 hours of operation and fine 150 µm filtration. Its bulkier build and modest propulsion make it slower than competing models. Suited for users who value hands-free, continuous surface cleaning and solar autonomy.

Professional reviewers and the manufacturer stress the high efficiency of the CX-300, noting its powerful 7,200 gal/hr suction, cordless low-power operation, and wall-climbing navigation as standout features. However, experts caution that warranty details are inconsistently presented and the unit's weight may be a drawback compared with lighter rivals.
Everyday users generally praise the cordless convenience, strong suction, and wall-climbing capability, especially for sandy or silty pools. Recurring themes include appreciation for the fine-mesh filter and the retrieval hook, while common complaints focus on the robot's heavy weight and occasional runtime reduction in heavily soiled water.

Reviewers commend the Surfer S2 for its comprehensive cleaning suite-150 μm filtration, a generous 4 L basket, DebrisGuard™ and SolarSeeker™-and its convenient app control. However, they consistently point out that the robot feels chunky and under-powered, with 2.5-inch propellers struggling to move the heavier chassis, making it slower than competing models.
While formal consumer reviews are scarce, the limited Q&A data shows users are pleased with the fine-level filtration and strong suction port, and no major complaints have surfaced in the available sources.
