The CHASING Hydro 4 SE is a corded robotic pool cleaner designed for inground pools up to 1614 square feet and 10 feet deep. It suits busy pool owners who want hands-free maintenance without the hassle of manual vacuums or battery charging. With its 40-foot cable and plug-in power, it delivers uninterrupted cleaning sessions lasting 1-3 hours depending on the mode and pool size.
Standout features include four cleaning modes: auto for full coverage, floor-only, wall-only, and ultra-clean for deep scrubbing. The 150W dual centrifugal pumps generate 5070 gallons per hour of suction, paired with dual silicone roller brushes that tackle algae, sand, and debris. Reviewers praise its wall-climbing ability and S-path navigation for thorough performance, with the 4.1L basket capturing even fine 180μm particles like hair and dander. Real-world tests show it revives neglected pools effectively.
Build quality is solid with a lightweight 14-pound plastic body that's easy to handle. The top-loading basket opens for quick rinsing without mess, and setup requires no assembly. Users appreciate the physical buttons for mode selection, though the app adds convenience for ultra-clean mode on land. It returns to the edge automatically for retrieval.
Drawbacks include cable tangling without a swivel, requiring occasional manual untangling, and app disconnection underwater, which is by design. A few reports mention weaker floor cleaning on uneven surfaces or early gyroscope issues.
Overall, the Hydro 4 SE offers excellent value for large inground pool owners prioritizing power and coverage. It transforms pool maintenance into a set-it-and-forget-it task, earning high marks for ease and results despite minor cable quirks.
