If you want an automatic pool cleaner that’s simple to use, easy to store, and doesn’t need extra hoses or a separate pump, the WINNY Cordless Robotic Pool Cleaner (2026 Model, 26WPC‑HJ1102P, “Transparent Green”) is a compelling option for above‑ground pools. With an 80‑minute cycle, dual‑stage filtration, cordless design, and self‑parking feature, this little robot aims to keep your pool floor clean with minimal effort.

In this review, you’ll see how well it works for typical backyard pools, how it compares to other cleaners, and whether it’s a good fit for your budget and setup.

Introduction

The WINNY 2026‑upgrade cordless robotic pool cleaner is designed specifically for above‑ground pools up to about 650 sq.ft (roughly 645 sq.ft in the product description) with flat or gently sloped bottoms. Measuring 14″L × 12″W × 7″H, it’s compact enough to lift out easily and store in a garage or closet.

Unlike traditional pool‑vacuum setups that rely on your pool’s filter and pump, this robot runs on its own built‑in battery, so you can drop it in the water and let it work without any extra plumbing.

Key Features

Here are the main features that make this WINNY model stand out:

• Advanced dual‑stage filtration system – An 180μm precision mesh filter plus a multi‑density foam layer work together to trap everything from fine silt and sand to larger debris like leaves.

• 80‑minute automatic cleaning cycle – Designed to fully cover an above‑ground pool (up to about 645 sq.ft) in roughly 80 minutes on a single charge.

• Cordless & self‑parking – No hoses or external power cords; the robot runs on its battery and docks itself at the edge of the pool when the battery runs low, making it easy to retrieve.

• Strong cleaning power – A safety‑certified high‑speed motor and dual scrubbing scrapers help remove dirt, algae, and debris from the pool floor.

• Universal pool compatibility – Works with flat or lightly sloped (≤15°) above‑ground pools and various surfaces, including PVC liners, vinyl, tile, and gunite.

• Compact and lightweight – Easy to lift out of the pool, with a solid handle and space to attach it to a standard pool pole (hook included; pole not included).

• Color: Transparent green – A modern, semi‑see‑through look that helps you monitor the filter and internal parts.

These features make the WINNY robot a practical choice for homeowners with above‑ground or small flat‑bottom inground pools who want automatic, low‑hassle cleaning.

Pros and Cons

Pros

• Easy setup and cordless operation – No hoses or extra pumps; just charge it, drop it in, and let it run.

• Self‑parking – Returns to the pool edge when the battery is low, so you don’t have to hunt for it in the middle of the pool.

• Dual‑stage filtration – The 180μm mesh plus foam layer captures both fine particles and larger debris, helping keep the water clearer.

• Good runtime for small–medium pools – 80 minutes is usually enough to cover an average above‑ground pool in one cycle.

• Universal surface compatibility – Works on common pool materials like PVC, vinyl, tile, and gunite, so it fits many setups.

• Portable and lightweight – Easy to carry, store, and attach to a pool pole if you want to guide it or move it manually.

Cons

• Limited to flat or gently sloped pools – Not designed for steep‑sided inground pools; it mainly focuses on the floor.

• Shorter runtime than some premium models – 80 minutes is solid for small pools, but larger or very dirty pools may need multiple runs.

• Filter basket needs regular cleaning – Like all robotic cleaners, you must rinse the filter after each use or risk reduced suction.

• Build quality not as robust as high‑end brands – Independent reviews note that cheaper cordless robots can feel a bit fragile or have weaker suction than pricier models.

• No app or smart controls – You can’t schedule or monitor it remotely via smartphone.

Overall, the WINNY 2026‑upgrade robot is best for casual, above‑ground pool owners who want automatic, low‑maintenance cleaning without a complex setup.

Detailed Review

Design and Build Quality

The transparent green plastic body gives you a glimpse of the internal components and filter, which can be helpful for checking if anything is clogged. The 14″L × 12″W × 7″H size keeps it compact while still providing enough surface area for the scrubbing brushes and suction.

The solid handle on top makes it easy to lift out of the water, even when it’s loaded with debris. The hooks included with the package let you attach the robot to a standard pool pole if you prefer to guide it manually or remove it without bending into the pool.

Filtration and Cleaning Performance

The advanced dual‑stage filtration system (180μm mesh + multi‑density foam) is one of the main selling points. In real‑world use, this setup helps:

• Capture fine silt and dust that can make water look cloudy.

• Trap larger leaves and small twigs so they don’t get sucked into your main pool filter.

The high‑speed motor and dual scrubbing scrapers work together to scrub the pool floor and dislodge stuck‑on dirt. On a standard above‑ground pool with a flat or slightly sloped bottom, the robot usually completes a full coverage cycle in about 80 minutes, leaving the floor noticeably cleaner.

For heavily soiled or neglected pools, you may want to run the robot twice in a row or assist with a manual brush, but for routine weekly maintenance, it does a solid job. The “self‑parking” feature means it gradually moves toward the edge and stops there when the battery runs low, making retrieval very easy.

Portability and Storage

Because it’s cordless and relatively lightweight, the WINNY cleaner is easy to:

• Store in a garage, shed, or closet when not in use.

• Carry from the house to the pool area without heavy hoses or pumps.

The transparent body and readable filter make maintenance straightforward: just rinse the filter and foam after each use, and wipe down the housing if needed. There’s no need to worry about tangled cords or complicated hose wrangling.

Who Should Buy This Product?

The WINNY 2026‑upgrade cordless robotic pool cleaner is ideal for:

• Above‑ground pool owners – Especially those with round, oval, or rectangular pools up to about 645–650 sq.ft.

• People with flat or gently sloped pool bottoms – Where the robot can move freely without steep walls.

• Busy homeowners or families – Anyone who wants to automate at least part of their pool cleaning without a big investment in equipment.

• Beginners new to robotic cleaners – Simple, cordless operation with minimal setup.

It’s less suited if you have:

• Large, steep‑sided inground pools – These often need a more powerful, wall‑climbing robot.

• Very heavy debris loads – Extremely dirty or neglected pools may still need extra manual cleaning.

Comparison with Similar Products

The WINNY robot sits nicely between basic manual vacuums and complex, wall‑climbing robots, offering good automatic cleaning with a simple cordless design at a lower price point.

Frequently Asked Questions

Does it clean the walls and waterline?

This model is mainly designed for floor cleaning in flat or gently sloped above‑ground pools. It may occasionally touch the liner near the edge, but it’s not optimized for full wall‑climbing. For thorough wall and waterline cleaning, a dedicated wall‑climbing robot or a pool brush is better.

How often should I run it?

For most above‑ground pools, running the robot once a week is enough to keep the floor clean if you regularly skim leaves from the surface. During heavy use or after storms with lots of debris, you might want to run it every 3–5 days in peak season.

How long does it take to recharge?

Reports from similar cordless pool robots suggest a 3–4 hour recharge time after a full 80‑minute cleaning cycle. Always follow the manufacturer’s instructions, but keep in mind that freshly charged batteries will give you the best performance.

Can it handle saltwater pools?

Many cordless robots like this one work in saltwater pools as long as the water chemistry is within normal ranges and the robot is rated for it. After use, rinse it with fresh water to help protect the housing and filter.

Is it noisy?

Robotic pool cleaners are generally much quieter than pool pumps. The WINNY robot produces a low‑level hum underwater, but it’s usually not loud enough to disturb conversation or relaxation near the pool.

Final Verdict

The WINNY 2026‑upgrade cordless robotic pool cleaner (Transparent Green) is a simple, efficient solution for above‑ground pools up to about 650 sq.ft. Its 80‑minute battery life, dual‑stage filtration, and self‑parking design make it easy to use and maintain, especially for homeowners who want to cut down on manual pool‑vacuuming time.

It won’t match the power and coverage of premium wall‑climbing robots, but for small‑to‑medium above‑ground pools and casual users, it’s a strong value‑oriented choice that can keep your pool floor noticeably cleaner with minimal effort.
