Aiper Surfer S2
Score: 70/100
Beatbot AquaSense 2
Score: 78/100Rankings
The Beatbot AquaSense 2 is a cordless robot that offers four-hour runtime, strong suction and sophisticated sensor-based navigation. Its main trade-offs are the lack of surface-cleaning capability and a relatively heavy unit. Best suited for owners of in-ground or above-ground pools up to 3,230 sq ft who value long runtime and smart 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.

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.
Professional reviewers rank the AquaSense 2 among the top pool-vacuum robots for 2026, praising its long battery life, strong suction and sophisticated sensor suite. They note its higher price relative to the Dolphin E10 but consider the added runtime and navigation capabilities to justify the cost, while calling out the missing surface-cleaning function for infinity pools.
Although direct user reviews are scarce, the available commentary suggests owners value the cordless convenience, single-session full-pool cleaning and easy maintenance. The most common positive remarks focus on the app control and the ability to tackle floors, walls and waterlines without manual effort.
