Hydro 4SE vs. Ezioov Y20: Surprising Cordless Efficiency for Pool Care In the ever-evolving world of pool maintenance, the debate between traditional corded systems and modern cordless innovations has never been more intriguing. Take the Hydro 4SE-a corded robotic pool cleaner designed for inground pools, boasting a 150W motor, a 180μm class basket filter, and the ability to climb walls and floors. Its 40-foot cable allows for uninterrupted coverage, making it a reliable choice for larger spaces. Yet, here comes the Ezioov Y20, a cordless contender that defies expectations with its 90-minute runtime, auto-parking feature, and lightweight build. While the Hydro 4SE excels in power and precision, the Ezioov Y20 offers unmatched convenience. Its cordless design eliminates the need for tangled wires, ideal for quick cleanings in both above-ground and flat-bottom inground pools. But don't mistake efficiency for simplicity-the Y20's compact form doesn't compromise performance, thanks to its dual-motor system and intuitive navigation. Meanwhile, the Hydro 4SE's corded setup ensures it can tackle sprawling areas, up to 40 feet in length, without needing frequent recharging. Amid this competition, other models like the WYBOT C1 or X1 present their own advantages, from extended runtime to intelligent route planning. However, the Hydro 4SE and Ezioov Y20 stand out as pioneers: one proving that corded systems can still deliver robust, no-compromise cleaning, and the other redefining flexibility with its cordless prowess. Whether you prioritize power or portability, the truth is, efficiency in pool care has never felt so dynamic.
