Tip: Charge Your Polaris® Cordless Robotic Cleaner for Long-Term or Winter Storage
October 27, 2026
Before you store your Polaris® cordless robotic cleaner for winter or long-term nonuse, charge it to 100%, as your user manual recommends. A full charge helps protect the battery through the off-season or extended downtime, so your cleaner is ready to go when you open the pool. This tip applies to all Polaris® cordless robotic cleaners, including the FREEDOM™ series and other cordless models.
Why batteries lose capacity over periods of non-use
Lithium-ion batteries slowly lose charge even when the cleaner is switched off. A battery stored below 50% can drain too far over several months, which can reduce its capacity or keep it from charging at all. Starting the off-season at a full charge gives the battery room to stay in a healthy range until spring.
How to store your cordless cleaner for winter or a long period of non-use
Remove the cleaner from the pool, rinse it with fresh, non-chlorinated water, and empty the filter basket.
Empty filter basket and gently clean it with a soft brush and mild soap.
Let it dry completely.
Charge the battery to 100% using the original charger.
Store the cleaner and charger indoors in a cool, dry place, away from direct sunlight and freezing temperatures.
Check your user manual for model-specific guidance, including whether a mid-season top-up charge is recommended.
Getting ready for use
Before the first clean of the season, plug in your cleaner and let it charge fully. Then run a full cycle to confirm it reaches its normal runtime.
If your cleaner won't charge up again
Check that the charger is plugged into a working outlet and the connection points are clean and dry, then leave it on for a full charge cycle.
FAQs
Should I charge my robotic pool cleaner before storing it for winter or for a period of non-use? Yes. Charge your Polaris cordless cleaner to 100% before winter or long-term storage, as the user manual recommends. A full charge helps protect the battery during the months it sits unused.
What happens if I store my cordless pool cleaner with a low battery? A battery stored below 50% can drain or degrade over winter. That can shorten runtime or keep the cleaner from charging next season.
Why won't my cordless pool cleaner charge after winter? The most common cause is a battery that drained too low during storage. Charge it fully, check the charger connection, and contact Polaris Customer Support if it still won't hold a charge.
Where should I store my cordless pool cleaner in the off-season? Store it indoors in a cool, dry place, out of direct sunlight and protected from freezing temperatures.
Do I need to recharge my pool cleaner during winter storage? Check your user manual for your model's guidance. Some owners top up the charge partway through a long off-season.
