The lightweight buoy holds the battery on the pool surface and tethers to the submerged robot via a 10 ft anti-snag cable. When the cycle ends, detach the buoy and charge it indoors without lifting the 16-20 lb robot to a charger. The Hydro 4 Battery cleans pools up to 1,614 sq. ft. with a 3.5-hour runtime per charge.\u003c\/p\u003e\n\u003cp\u003eThe Hydro 4 Battery shares the same robot chassis, dual turbine 5,070 GPH suction, 4.1L dual-zone filter basket, and HydroCurve S-shaped navigation as the Corded Mode version. Three cleaning modes (Auto, Wall Enhanced, Floor Only) combine with three runtime presets (1-hour Fast, 2-hour Regular, 3-hour Ultra) for nine configurations. The standout cordless-specific feature is underwater Bluetooth and Wi-Fi communication: the floating buoy maintains a wireless link to the robot while it operates submerged, enabling real-time mode switching, manual navigation, and one-click retrieval through the Poolmate Bot app.\u003c\/p\u003e\n\u003cp\u003eThis is the right Hydro 4 configuration for owners who want true cordless freedom on large residential pools. The floating buoy design eliminates both cord tangling and the lift-the-robot-to-charger step that limits other cordless cleaners. Compared to the Corded Mode variant, the Cordless trades unlimited runtime for portability and adds real-time underwater app communication. Compared to the Beatbot Sora 30 (3,229 sq. ft. coverage), the Hydro 4 Battery offers smaller per-cycle coverage but adds the detachable buoy charging system that Sora models lack.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 0 0 500px; max-width: 500px; width: 100%;\"\u003e\u003cimg src=\"https:\/\/www.image2url.com\/r2\/default\/images\/1779629813863-3bae1e4a-d60f-40dc-b9ea-b789b1633a90.jpg\" alt=\"Chasing Hydro 4 Battery robotic pool cleaner with floating buoy battery on pool surface\" style=\"width: 100%; height: auto;\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003chr\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; gap: 20px; align-items: flex-start;\"\u003e\n\u003cdiv style=\"flex: 1; min-width: 300px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Source:\u003c\/strong\u003e Floating buoy battery (detachable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRuntime:\u003c\/strong\u003e 3.5 hours per charge cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharging Time:\u003c\/strong\u003e 4 hours (buoy charged separately from robot)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuoy Tether Cable:\u003c\/strong\u003e 10 ft (3 m), anti-snag design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuction Power:\u003c\/strong\u003e 5,070 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor System:\u003c\/strong\u003e Dual turbine pumps (Deep-Sea DC motor x3)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pool Size:\u003c\/strong\u003e Up to 1,614 sq. ft.

The detachable floating buoy is the operational difference: charge the buoy indoors on a counter or shelf, leave the robot in place or store it dry, and reattach for the next cycle. This workflow particularly suits owners with limited deck access, second-home owners who travel between properties, and anyone who finds cord management on a 50 ft tether inconvenient.\u003c\/p\u003e\n\u003cp\u003eFor luxury residential properties with infinity edges, attached spas, or complex multi-level pool designs, the real-time underwater Bluetooth and Wi-Fi communication enables manual navigation to clean specific zones the autonomous algorithm misses. Pool service contractors managing premium residential accounts gain a portable cordless solution that can be deployed across a portfolio of properties without unspooling and respooling a 50 ft cable at each stop.\u003c\/p\u003e\n\u003cp\u003eThe Hydro 4 Battery is less suited for owners who need unlimited cleaning runtime (consider the Corded Mode variant), pools larger than 1,614 sq. ft.
