Dolphin E10
Score: 68/100
Aiper Surfer S2
Score: 70/100Rankings

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.

The Dolphin 500966 is a lightweight, entry-level robotic cleaner with smart navigation and a top-load filter, ideal for small above-ground pools. Its main trade-offs are the lack of wall-climbing ability and missing smart-app features. Best suited for owners who need a simple, low-maintenance floor-only solution.

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.
Choose the 500966 for a lower-cost basic model; choose the E10 if you want a newer version with similar capabilities.
