Robotic leaf skimmers are designed to float on the water and quietly sweep away leaves, insects, and surface debris. They’re incredibly convenient for keeping your pool surface clean. But a common question arises: can you leave them in the pool 24/7?
This guide answers that question clearly by looking at manufacturer guidance, real-world usage conditions, and long-term effects. Whether you use your skimmer daily or only after storms, we’ll help you make the best decision for longevity and reliability.

📦 What Manufacturers Recommend
Most brands recommend removing the skimmer when it’s not actively in use.
Solar-powered models often lack full waterproof battery seals and aren’t designed for permanent submersion.
Prolonged exposure can result in battery wear, algae growth, and UV damage to outer casings and electronics.
Manufacturers like Betta, Aiper, and Zigma all suggest regular inspection and occasional removal to rinse and dry the skimmer.

🌞 When It’s Okay to Leave It In
There are times when it’s perfectly acceptable to leave your robotic skimmer in the water:
During peak swim season (spring and summer), especially if you’re running the skimmer daily
If you have a UV-resistant model with sealed electronics
Your pool is covered at night or when not in use, reducing sun and chemical exposure
You’re actively monitoring it and cleaning the tray regularly
Daily use with light to moderate debris levels won’t harm the unit, especially if it’s solar-powered and made for long runtime.

⚠️ When You Should Remove It
Certain conditions can accelerate damage or reduce the performance of your skimmer:
Heavy winds, thunderstorms, or nearby falling branches that could hit and damage the unit
Pool closings for winter or off-season, especially in cold climates
After shock treatment or high chlorine dosing that could corrode parts
If the skimmer hasn’t been used for more than 48–72 hours
Leaving it idle for too long can also allow algae to take hold on the hull or inside the tray.

🔋 Risks of Leaving It In Too Long
🔹 Battery Degradation
Constant exposure to water, heat, and solar charging cycles can reduce overall battery lifespan.
Battery capacity may diminish faster if the skimmer never gets time to dry or cool down.
🔹 Algae and Debris Buildup
Floating debris or stagnant conditions can lead to algae buildup on the hull or filter tray.
This not only affects performance but may cause odors or require more cleaning.
🔹 UV and Chemical Wear
Continuous UV exposure fades plastic and weakens seal integrity.
Prolonged chlorine contact, especially after shocking, may damage electronic compartments or battery compartments.
🪜 Best Practices for Skimmer Longevity
Want to maximize your robotic skimmer’s lifespan?
Rinse the unit after use, especially after high-chemical cleaning
Let it fully dry before storage or charging
Store it in a shaded, well-ventilated area when not used for more than 2 days
Follow the user manual for charging cycles, runtime, and tray maintenance
Use a mesh bag or bin to store it off the ground and away from pests or moisture

✅ Final Advice
Robotic skimmers are made to work autonomously for long stretches, but they’re not meant to float endlessly without care.
Leaving it in during summer is fine if you clean it regularly and avoid major weather or chlorine treatments. For anything longer or during low-use periods, take the time to rinse, dry, and store it properly.
This protects your investment and ensures your pool stays sparkling, with less need for costly repairs or replacements down the line.
