Aiper Surfer S2
Score: 70/100
iGarden K36
Score: 79/100Rankings

The iGarden K36 is a cordless robotic pool cleaner with strong 3D navigation and a long 220-minute floor-only runtime. Its main trade-offs are a heavy water-filled weight and occasional connectivity hiccups. Best suited for owners of smaller inground or above-ground pools who value smart scheduling and fine-debris filtration.

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 commend the K36 for its lightweight build, effective fine-debris filtration, and robust 3D navigation with a turbo boost for stubborn stains. However, they caution that the heavy water-filled weight, occasional connectivity hiccups, and reliance on future firmware for full wall cleaning are drawbacks.
There are currently no consumer reviews or user‑generated feedback available, so everyday user sentiment cannot be assessed at this time.
Surfer S2 is ideal for users wanting set-and-forget solar cleaning; K36 is better for those needing powerful turbo cleaning and programmable AI timers.
