Dolphin Proteus DX3
Score: 74/100
Aiper Surfer S2
Score: 70/100Rankings

The Dolphin Proteus DX3 offers wall-climbing, smart navigation and a powerful 4000 gph suction for comprehensive cleaning of pools up to 33 ft. It falls short on advanced scheduling, app integration and waterline scrubbing. Ideal for budget-conscious homeowners who need floor and wall cleaning without smart-home features.

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.

Industry listings and retailer copy present the Proteus DX3 as a solid entry-level robotic cleaner, praising its lightweight build, strong suction, and straightforward plug-and-play operation, while consistently noting the missing smart features such as timers, app control, and waterline scrubbing as drawbacks.

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.
