Dolphin E10
Score: 68/100
Zyerch Cordless Pool Cleaner
Score: 70/100Rankings
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.
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.

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.
