You’ll find the Chasing Hydro 4 SE is a compact, 14 lb corded robot built for pools up to 40 ft that reliably scrubs floors, climbs walls, and lifts light waterline scum. Its 150W dual centrifugal pumps deliver strong, efficient suction and double‑suction pickup, while dual silicone rollers and a 4.1 L ultrafine 180 μm filter trap sand, hair, and leaves. Bluetooth app modes add control but range is limited; keep going for full performance, setup, and value details.
Some Key Takeaways
- Powerful 150W dual centrifugal pump claims 5,070 GPH suction for fast, efficient debris removal on floors and walls.
- Hydrocurve S‑path navigation and wall‑climbing reliably cover floors, seams, steps, and the waterline for routine cleaning.
- 4.1 L ultrafine 180 μm filter basket and dual silicone rollers capture leaves, hair, sand, and fine grit with low clogging.
- Poolmate Bot app adds Ultra Clean mode and finer control; Bluetooth is poolside-only and can drop with distance.
- Lightweight 14 lb corded design with 40 ft buoyant cable offers easy setup, modest energy use, and homeowner-friendly maintenance.
Chasing Hydro 4 SE At a Glance : Who It’s For and Core Specs
If you want a powerful, portable cleaner for an inground pool up to 40 ft long, the Chasing Hydro 4 SE (PoolmateHydro4SE) is built for that job: DEENO’s 2026 corded robot weighs 14 lb, runs on AC110–120V through a 150W dual centrifugal pump and claims 5,070 GPH suction with double‑suction efficiency. You’ll appreciate clear core specs: 4.1 L ultrafine 180 μm filter, 40 ft buoyant cable, Hydrocurve S‑path, wall climbing and four modes. Ideal buyers are committed pool owners who want powerful, portable automation, app convenience and reliable debris capture without complex setup. This model is well suited for homeowners who value automated maintenance of their outdoor spaces and the benefits of robotic pool vacuums.
Real-World Cleaning Performance : Floors, Walls, and Waterline
While testing the Hydro 4 SE on typical inground surfaces, you’ll notice its S‑path navigation and double‑suction give consistently thorough floor coverage, pulling settled sand and medium debris into the 4.1 L, 180 μm basket without frequent passes. You’ll appreciate measurable surface agitation from the silicone rollers on textured finishes; it loosens biofilm and grit without scrubbing damage. Walls climb reliably, tracking seams and steps, and edge scalloping keeps the unit from snagging on coves. Waterline pickup is competent for light scum but may need targeted ultra‑clean cycles via the app for stubborn stains. Overall, it’s dependable and inclusive for shared pool care. It’s especially well-suited for homeowners who value effortless pool cleaning and relaxing outdoor living.
Filtration, Brushes, and Debris-Handling Tested
Having seen how the Hydro 4 SE handles floors, walls, and the waterline, let’s look at how its filtration, brushes, and debris handling perform in everyday use. You’ll find the 4.1 L ultrafine 180 μm basket captures leaves, hair, and fine grit without frequent overflows, but filter maintenance is straightforward: rinse and shake dry after heavy runs. Dual soft silicone roller brushes scrub efficiently; brush longevity looks promising in tests, resisting wear on rough surfaces. Double-suction pumps pull debris into the basket rather than clogging intakes. Overall, debris-handling is reliable, low-effort, and suited for shared pool ownership. For longer filter life, choose cartridges designed to keep your pool clean with proper filtration and replace them according to manufacturer recommendations.
Controls, Connectivity, Cable Length, and Ease of Use
Because DEENO gives you two control paths, you can choose quick onboard operation or finer app-based settings without fuss. You’ll use body touch buttons for fast starts and the Poolmate Bot app for precise App navigation — Ultra Clean mode is app-only. Bluetooth works from poolside but can drop if you wander; there’s no cloud control. The included 40 ft buoyant safety cable suits most inground pools; Cable management is simple thanks to the light, tangle-resistant design. Setup is plug-and-play with no assembly, and controls feel deliberate and reliable, so you and fellow pool owners adapt quickly. Our shop carries a range of complementary pool maintenance tools useful for keeping the rest of your outdoor space in top shape.
Value Check : Energy Use, Warranty, Pros vs Cons, and Buying Recommendation
Let’s break down what you’re getting for the price: the Hydro 4 SE pairs a relatively low 150W AC motor with a reported 5,070 GPH suction, so it runs far more efficiently than many pressure- or high-wattage cleaners and should keep your electricity costs modest for regular use. You’ll like the clear energy efficiency trade-off: strong suction with low draw. Limited warranty coverage exists—check DEENO for terms. Pros: lightweight, smart cleaning paths, ultrafine filtration, app modes. Cons: app-dependent ultra-clean, Bluetooth limits, limited warranty. Recommendation: buy if you want efficient, modern automation and community-tested reliability. Enhance your outdoor living with smart pool automation that integrates the cleaner into your backyard systems.
Some Questions Answered
Can It Run on Solar Power or Battery Backup?
No — it isn’t solar compatible and won’t run on battery backup. You’ll need AC110–120V power for the Hydro 4 SE’s 150W dual centrifugal pumps; there’s no onboard battery option. If you want off-grid use, you can pair an external inverter/AC power source sized for continuous 150W+ draw, but that’s your responsibility. You’ll feel safer checking inverter specs and cable routing so everyone in your pool community stays confident and included.
Is It Safe to Use With Saltwater or Chlorine Pools?
Yes — you can use it in both salt compatibility and chlorine pools, but mind maintenance and material corrosion. You’ll get reliable cleaning; the Hydro 4 SE’s materials resist typical pool chemicals, yet prolonged high salinity or improper storage can accelerate corrosion of connectors and metal parts. You should rinse, dry, and inspect components regularly, follow manufacturer maintenance, and store the unit sheltered to keep performance consistent and your pool-cleaning community confident.
How Noisy Is It From Poolside During Operation?
You’ll hear a low hum from poolside with noticeable water splashing, but it’s not overwhelmingly loud. The 150W dual pump emits steady, muted noise while the Hydrocurve S-path and brushes work; you’ll mostly notice mechanical vibration and intermittent splashes when climbing walls. In group settings it’s unobtrusive—comfortable for shared pools—though ultra-clean mode can raise intensity slightly. Overall, it feels like a background appliance rather than a disruptive engine.
Are Replacement Parts (Brushes/Filters) Readily Available?
Yes — replacement brushes and filters are generally available, but availability varies. You’ll find OEM and aftermarket availability through DEENO dealers and pool-part retailers; check compatibility with your limited warranty before fitting non‑OEM parts. You’ll want the 4.1 L filter basket and dual silicone rollers sized for the Hydro 4 SE. If you join user groups, you’ll get sourcing tips and shared vendor links to keep your cleaner running reliably.
Can Multiple Units Operate Simultaneously in One Pool?
Yes — you can run multiple units in one pool, but they won’t perform synced cleaning. You’ll get faster coverage and redundant suction, yet each Hydro 4 SE operates independently, so paths may overlap. Use staggered start times and separate cables to reduce tangling. You’ll enjoy improved debris removal and teamwork-like efficiency, but don’t expect coordinated navigation or centralized control — only parallel, cooperative results from separate robots.
