Key Features
Battery Performance
The Seahorse’s 2500 mAh lithium battery powers up to 60 minutes of uninterrupted cleaning on a single charge, ideal for small to mid-sized pools. It delivers consistent power throughout the run, avoiding the gradual suction drop-off common in cheaper units. This runtime covers an 18-foot above-ground pool twice over or a daily 10-15 minute spa cleaning session for a week.
Dual-Phase Filtration System
This vacuum employs two layered filters to maximize debris capture. A 125 μm mesh filter traps leaves and larger particles, while a 250 μm sponge filter captures fine sand, silt, and calcium residues. By separating debris types, it prevents clogging and maintains strong suction with minimal maintenance. After a simple rinse, both filters restore peak performance, keeping your pool floor spotless without repeated filter swaps mid-clean.
Ergonomic Telescopic Pole
The 65-inch aluminum pole extends and locks securely in three positions, letting you reach corners, stairs, and deep ends without bending over. Its lightweight construction supports up to four times the vacuum’s weight when held above water, ensuring stable control even at full extension. A rubberized grip at the handle end reduces slippage with wet hands, making long cleaning sessions more comfortable and reducing fatigue.
Versatile Cleaning Heads
Switch effortlessly between the 10.5-inch brush head for scrubbing algae and the narrow suction head for tight corners and vinyl seams. The brush head’s resilient nylon bristles agitate stubborn deposits, while the suction head adapts to edges and steps where debris accumulates unseen. This flexibility transforms the Seahorse into both a power scrubber and a precision vacuum in one compact tool.
Firsthand Experience
When I first unpacked the Seahorse, its components felt reassuringly lightweight and snapped together effortlessly in under three minutes. The telescopic pole extended smoothly, and the vacuum head locked in place with a satisfying click. Holding it in one hand, I could easily balance the weight and maneuver around objects without straining my wrist. Sitting poolside, I admired the compact design and sturdy aluminum pole, a reassuring sign that it could withstand daily use without tools or complicated instructions.
My initial test focused on the shallow end of an inflatable hot tub laden with sand after a windy afternoon. The powerful 30 W motor kicked in instantly, and within seconds I watched the sponge filter gobble up fine granules that a traditional net left behind. The 16 gallons per minute flow accelerated debris collection, and I completed a full pass in under five minutes. Seeing that level of performance convinced me the Seahorse was built for serious cleaning jobs.
After a week of daily use, I noted the battery gauge still hovered above half after four spa sessions. Charging to full took about four hours, matching the advertised spec, and the vacuum held its charge for three days of intermittent cleaning. Even after clearing heavy calcium deposits from a gunite pool floor, the dual-phase system showed no signs of clogging. A quick rinse under the garden hose restored suction like new.
Noise levels surprised me in a good way: at roughly 68 dB measured three feet away, the unit operated quieter than a conventional shop vacuum, preserving the relaxing atmosphere around my backyard oasis. The touch controls on the handle were intuitive, letting me toggle power on and off without wet gloves slipping. I appreciated the absence of hoses or cords tangling around my ankles.
After four weeks, maintenance proved minimal. Emptying the 1.3-liter bin and rinsing both mesh and sponge filters took under a minute. Although the plastic housing requires some care to avoid scratches, regular storage in a cool, shaded area prevented sun damage and preserved the vacuum’s vibrant teal finish. Overall, the Seahorse balanced performance with user-friendly upkeep.
Pros and Cons
Customer Reviews
Reviews for the Seahorse reflect a strong overall satisfaction rate, particularly praising its cordless freedom and dual-phase filter efficiency. Many users note its impressive ability to lift embedded calcium and fine sand, while common critiques focus on the pole’s reach and the unit’s lightweight feel. With 124 ratings skewing heavily toward five stars, most buyers find it a valuable addition to their pool care toolkit, though a few mention challenges in larger or debris-heavy environments.
I recently tackled a spa filled with calcium deposits and the Seahorse pulled out more grit in one pass than my old cleaner did in weeks.
Super easy to use—its sponge filter grabbed every speck of dirt without draining my 18′ round pool once.
The vacuum glides nicely but the telescopic pole doesn’t extend far enough, making me bend uncomfortably to reach corners.
Suction power is solid, yet the plastic housing feels fragile when I accidentally knocked it against the pool wall.
It struggled with heavy leaf debris in my above-ground pool and clogs the mesh filter too quickly.
Comparison
Compared to traditional manual hydro-siphon vacuums, the Seahorse delivers consistent suction without draining pool water or relying on hose pressure. Unlike gravity-fed models that lose vacuum force as the container fills, the Seahorse maintains full power until the battery depletes, ensuring a uniform clean from start to finish. This advantage makes it a stronger choice for pools with significant calcium build-up or fine sediment.
When stacked against hose-attached suction cleaners, the cordless Seahorse offers unmatched mobility. Hose vacs depend on a pump’s water pressure and can tangle or kink, limiting reach and requiring constant repositioning. By contrast, the Seahorse’s self-contained design lets you focus solely on debris removal, improving efficiency in hard-to-reach corners and on pool walls where hoses often miss spots.
Robot pool cleaners excel at floor surfaces and automated cycles, but they typically struggle with stairs, vinyl seams, and tight corners. The Seahorse shines in these areas: its slim, handheld form factor and interchangeable heads allow for targeted scrubbing and precision vacuuming. For a comprehensive cleaning regimen, many owners pair a robotic cleaner for large areas with the Seahorse for detailed touch-ups.

Conclusion
The Seahorse by PoolMr offers a compelling blend of cordless convenience, potent 30 W suction, and dual-phase filtration that outperforms many manual and hose-dependent vacuums. Its lightweight design and intuitive controls make pool maintenance less of a chore, especially for homeowners with spas and above-ground pools. For those with pools under 20,000 gallons craving spot-on cleaning without water loss or hose entanglements, it represents excellent value in the mid-range price segment.
However, if your priority is heftier construction for heavy-duty use in commercial or Olympic-sized pools, or if you frequently tackle large volumes of oversized debris, you may find the pole reach and plastic housing limitations frustrating. At its current market price, it delivers standout performance for residential users, and I recommend checking the latest deals to maximize your savings on what is already a strong pool care companion.
