Aiper Surfer S2
Score: 70/100
Zyerch Cordless Pool Cleaner
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 Zyerch SAT25 is a cordless robotic pool vacuum offering up to 150 minutes of runtime, strong 4800 GPH suction and wall-climbing sonar navigation. Its low ground clearance and relatively heavy wet weight may hinder use on deep steps or frequent handling. Ideal for homeowners seeking long cordless operation for pools up to 50 ft.

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.
“cordless workhorse”
“potentially low ground clearance”
Professional reviewers describe the SAT25 as a robust, cordless workhorse that combines solid construction, side‑profile wheels, underwater brushes, and a quick‑latch debris door. They commend its sonar‑guided navigation and wall‑climbing ability, as well as the extended 150‑minute runtime, while noting the low ground clearance and wet weight as potential drawbacks in real‑world use.
Everyday users echo the professional praise for cordless convenience, long runtime, and easy debris emptying, highlighting the wall‑climbing function as a major benefit. The main consumer concerns revolve around the unit’s weight when wet and questions about durability of the low‑clearance design, though no widespread complaints have emerged yet.
