OUCAXIA Y50S Smart Cordless Robotic Pool Cleaner Review

If you want a robotic pool cleaner that does floors, walls, and waterline scrubbing—without being tethered by cables—the OUCAXIA Y50S might be just what you’re looking for. This model boasts an upgraded 110W brushless motor, wall-climbing capability, smart path navigation, and a cordless, tangle-free design, aiming to deliver comprehensive pool care for inground pools.

OUCAXIA Y50S Robotic Pool Cleaner, Upgraded Motor, Powerful…

【Tangle-Free Cordless Pool Vacuum】The Y50S pool vacuum cleaner thoroughly cleans pool floors, walls, and waterlines, ensuring no spot is missed. With tangle-free cordless design, this robotic pool cleaner moves freely in above & in-ground pools. It delivers a sparkling clean with minimal effort—Ideal for daily maintenance or getting your pool ready for weekend gatherings.

Design & Build

The OUCAXIA Y50S is built with a focus on durability and practical use:

Cordless design: no trailing cords or hoses to limit movement or get tangled.
Minimum water depth requirement: needs ~50 cm (20 in) of depth to activate and operate safely.
Dual PVC roller brushes and anti-slip treads help it grip surfaces when climbing.
Top-load 4 L filter basket: large capacity, easy to open and rinse.
Self-parking / automatic retrieval: when its cycle ends or battery is low, the Y50S parks near the pool edge for easier retrieval.
Quick-drain design: water is released quickly when lifted, reducing drips.

The build is decent for its intended use—solid plastic chassis, functional seals, and design elements that make daily handling easier.

Motor & Suction Power

One of the key highlights of this model is its motor and suction capabilities:

Equipped with a 110W brushless motor, designed for reliability and efficiency.
Advertised suction power is 3,120 GPH (gallons per hour), which gives it the strength to pull in leaves, small twigs, sand, and debris.
Because it’s cordless, having strong suction is essential to maintain cleaning performance without relying on cable power.

This motor-suction combo is suitable for typical residential debris loads, though very heavy leaf or branch clutter may challenge it.

Wall Climbing & Waterline Function

A big selling point of the Y50S is its ability to clean more than just the floor:

The unit climbs vertical walls using its traction treads and brushes, allowing it to scrub surfaces that many floor-only units neglect.
The waterline brush helps remove grease, scum, and residue that accumulate at the tile/water boundary—a common trouble zone in pools.
It adjusts to different wall angles and surfaces (gunite, fiberglass, vinyl, tile) with adaptive grip control.

This makes it more “full coverage” than many basic robotic cleaners which only handle flat bottoms.

Navigation & Cleaning Modes

To avoid random motion and missed spots, the Y50S boasts multiple smart modes:

4 main modes: floor-only, wall-only, waterline-only, and full-coverage (combining the above).
Smart path navigation: uses built-in gyroscope and ultrasonic sensors to map and optimize its route, following Z-patterns or S-patterns to reduce overlap.
Can adapt to obstacles (ladders, drains, lights) by redirecting its path—helping it avoid getting stuck.

These navigation features help it clean more efficiently with fewer wasted cycles.

Battery & Runtime

Battery performance is critical for cordless units like this:

The Y50S uses a 5,100 mAh battery, which is relatively large for this class.
It claims coverage up to ~200 m² (≈ 2,153 sq ft) in a single run under favorable conditions.
Charging time is about 4–5 hours for a full recharge.
Because of the battery limit, runtime is a practical constraint: in larger or heavily soiled pools, it may need multiple cycles or partial recharge breaks.

In many typical pools, the battery is sufficient, but performance depends on pool size, shape, and debris load.

Usability & Convenience

The Y50S is designed to minimize your effort:

Plug-and-play setup—drop into the pool, select mode, and let it clean.
Automatic retrieval / self-parking near pool edge simplifies removal.
Because it’s cordless, there’s no need to manage hoses, cables, or external pumps.
Top-loading filter means minimal bending or flipping the unit to access debris.
Quick water drain helps reduce drips while transporting or storing it after use.

These features improve daily usability, making pool maintenance far less labor-intensive.

Maintenance & Durability

Like all pool robots, upkeep determines lifespan:

Empty and rinse the filter basket after each run to keep suction efficiency high.
Inspect brushes, tracks, and seals periodically for wear.
Rinse off the exterior (especially in saltwater pools) to prevent chemical corrosion.
Check battery health over time—rechargeable packs degrade after many cycles.
Store indoors or under cover when not in use to reduce UV and weather exposure.

With reasonable care, its parts should last several seasons before needing replacement.

Pros & Cons

Pros
✔ True cordless operation—no tangling cables
✔ Cleans floor, walls, and waterline
✔ Strong motor + suction (3,120 GPH)
✔ Smart navigation with multiple modes
✔ Large filter capacity, top-load design
✔ Self-parking and easy retrieval

Cons
❌ Battery runtime is limited—may struggle in larger or heavily soiled pools
❌ 4–5 hour charge time
❌ In extreme pool geometries or with many obstacles, navigation may struggle
❌ Replacement parts (battery, brushes) might be costly
❌ Lift-out weight might be nontrivial when full of water

FAQs

Q: What is the minimum water depth for use?
Requires at least 50 cm (≈20 in) of water to operate properly.

Q: Can it climb walls and scrub the waterline?
Yes—it has traction treads and a dedicated brush for waterline scrubbing.

Q: How long does one cycle last?
Depends on pool size, mode, and debris load—battery capacity suggests a full cycle for many medium-size pools.

Q: What pool surfaces does it support?
It works with gunite, vinyl, fiberglass, tile, and more, thanks to adaptive climbing and brush control.

Q: What is the filter capacity?
It holds ~4 L of debris, which is decent for daily use before needing cleaning.

Final Verdict

The OUCAXIA Y50S Robotic Pool Cleaner is a well-rounded cordless option if you want more than floor cleaning—you get wall climbing, waterline scrubbing, and smart navigation in one unit. Its motor and suction specs are solid, and its usability features (self-parking, top-load filter) make it easier to handle day to day.

However, battery runtime is still the major constraint. If your pool is very large, heavily shaded, or has a lot of debris, you may push its limits. But for many typical inground pools, this robot offers a powerful boost in convenience and cleanliness.
