The WYBOT S2 Solar Pool Vacuum Cleaner takes a different approach to robotic pool cleaning—using built-in solar charging to extend run time and reduce the need for frequent manual charging. Designed for above-ground and smaller in-ground pools, it promises cordless convenience, eco-friendly operation, and a low-maintenance cleaning routine.
We tested the WYBOT S2 over several weeks to see if solar-assisted power can deliver consistent cleaning performance without the drawbacks of fully battery-dependent models.
First Impressions
The WYBOT S2 has a slim, lightweight design with a flat top housing the solar panel. It’s clearly built for portability, weighing less than most cordless robotic cleaners. The build feels sturdy enough for daily use, though it’s aimed at smaller pools rather than large in-ground installations.
Because it’s cordless, there’s no control box or cable—just place it in the pool and let it run. The onboard rechargeable battery is topped off by sunlight while in use, which is the standout feature of this model.
Key Features
- Power Source: Built-in lithium battery with solar charging assistance.
- Design: Cordless, lightweight body for easy handling.
- Coverage: Focused on pool floor cleaning.
- Run Time: Up to 120 minutes per charge, extended when in direct sunlight.
- Filtration: Removable filter basket for debris collection.
- Navigation: Simple pattern-based movement for coverage.
- Target Use: Above-ground pools and small in-ground pools.
Performance Testing
We ran the S2 in both a 15’ above-ground round pool and a small 12’ x 24’ in-ground pool. Here’s how it performed across different cleaning conditions:
Floor Cleaning
The S2 did a good job collecting leaves, sand, and small debris from the pool floor. Because it lacks active brushes, it relies mostly on suction, which works fine for loose debris but isn’t as effective on stuck-on dirt or algae. In clear water conditions, the results were solid; in dirtier pools, a manual brush before cleaning helped significantly.
Navigation
The movement pattern is more random than methodical, meaning some spots may be missed on a single cycle. However, in smaller pools, the S2 usually covers most areas within its 1.5–2 hour run time.
Debris Handling
The removable basket holds a decent amount of debris for its size. It handles small leaves and bugs easily, though large leaf clusters can block the intake, requiring a mid-cycle emptying.
Solar Charging Performance
The solar panel works best in direct, midday sunlight. On sunny days, we noticed the S2 extended its runtime by 20–30 minutes beyond its base battery capacity. On cloudy days, it relied entirely on its pre-charged battery, which still delivered around 90–100 minutes of cleaning.
Ease of Maintenance
Maintenance is simple—remove the filter basket, dump out the debris, rinse with a hose, and snap it back in. Because it’s lightweight, lifting it from the pool is easy, even for kids or older pool owners.
Energy Efficiency
Since it partially charges via solar energy, the S2 reduces the frequency of plug-in charging. When needed, charging from a wall outlet takes about 4–5 hours, but many owners can run multiple cleaning sessions between charges if there’s strong sunlight.
Durability Over Time
While long-term durability will depend on care and storage, during our testing the S2 held up well. The seals kept water out, and the lightweight body showed minimal wear. Storing it in the shade when not in use is recommended to protect the solar panel and extend battery life.
Pros
- Solar-assisted charging extends run time
- Completely cordless operation
- Lightweight and easy to handle
- Simple to clean and maintain
- Quiet operation
- Eco-friendly design
Cons
- Random cleaning pattern may miss spots
- Not designed for wall or waterline cleaning
- Less effective on stuck-on dirt without brushing first
- Small debris basket compared to larger robots
Who Should Buy the WYBOT S2?
The S2 is best for pool owners who:
- Have small to medium above-ground or compact in-ground pools
- Want a lightweight, cordless cleaner
- Prefer minimal charging and eco-friendly operation
- Don’t need wall or waterline cleaning
Tips for Best Performance
- Place the cleaner in the pool during peak sunlight for maximum solar benefit.
- Brush stubborn dirt before running the cleaner.
- Empty the debris basket after each cycle.
- Store the unit in a shaded area when not in use.
Final Verdict
The WYBOT S2 Solar Pool Vacuum Cleaner offers a unique combination of cordless convenience and solar charging. While it doesn’t replace a high-powered robotic cleaner for large pools, it’s an excellent fit for smaller pools where ease of use, quiet operation, and eco-friendly features matter most. For above-ground pool owners who want a set-and-forget daily cleaner, the S2 is a practical and affordable choice.
If your pool fits its size and cleaning limitations, the WYBOT S2 can help keep your water clear with less charging and less hassle.
