How to Store a Pool Robot for Winter: Steps Before You Close the Pool
Run one last full clean before closing, then rinse, dry, charge to the maker's storage level and keep the robot indoors above freezing. Here is the full routine and the mistakes that kill batteries.
Last updated: October 2026
Run a full cleaning cycle near the end of your closing routine, then take the robot out for the season. Rinse the filters and body, let every part air dry, charge the battery to the level your manual gives for storage, and keep the robot and its dock indoors in a dry place that stays above freezing. Never store it wet, empty or in an unheated shed.
Should you run the robot before closing the pool?
Yes. Beatbot recommends a full robotic cleaner cycle before closing for the season. The reason is simple: whatever is in the pool when the cover goes on stays there until spring. Leaves and dirt left on the floor rot, feed algae and stain. A clean pool under the cover opens cleaner.
Beatbot is specific about timing. Run the cycle near the end of your closing routine, after you have balanced the water but before you lower the level, add winterizing chemicals and cover the pool.
Make it a full clean. Beatbot notes that a proper pre-closing clean should reach the floor, the walls and the waterline, not the floor alone.
Where does the robot fit in the steps to winterize a pool?
Closing steps vary by pool type and climate, so follow your pool builder's or pool professional's instructions for chemicals, water level and plumbing. The robot's place in the order is consistent:
Remove ladders, toys and floating items.
Skim the surface and brush the walls and steps.
Balance the water.
Run the robot: floor, walls and waterline.
Take the robot out. Empty and rinse the filter.
Lower the water level if your closing method calls for it.
Add winterizing chemicals as directed for your pool.
Drain and protect pump, filter, heater and lines as directed.
Cover the pool.
Clean, dry, charge and store the robot.
A surface skimmer helps in the weeks before closing, when leaves are falling fastest. See do solar pool skimmers work?
How do you clean the robot for storage?
Do this the same day it comes out.
Empty the debris basket or filter box.
Rinse filters thoroughly until the water runs clear. Fine filters hold silt you cannot see.
Rinse the whole body with fresh water to remove chlorine or salt. Aiper calls a fresh water rinse the single most effective way to prevent corrosion.
Check brushes, tracks and wheels for hair, string and grit.
Check the intake for a wedged leaf stem or pebble.
Wipe the charging contacts dry.
How dry is dry enough?
Completely. Beatbot's advice is to let every part air dry so no moisture is sealed inside. Leave the filter out of the robot, stand it so water drains, and give it a day or two in a ventilated spot out of direct sun. Putting a damp robot in a bag or box invites mildew and corrosion.
What charge should the battery be at?
Follow your manual. Makers differ, and this is the step that matters most for a cordless robot. Beatbot's guidance: set the battery to the charge level your manufacturer recommends for storage, not empty and not left at a random level.
Two things damage a stored lithium battery, per Beatbot: sitting fully drained for a long time, and freezing hard. A battery that sat empty all winter may not take a charge in spring.
If your manual gives no storage figure, ask us for your model and we will look it up with the maker. Then top it up partway through the winter if the manual says to.
Where should you store it?
Beatbot's wording is a good standard for any brand: a dry indoor spot that stays above freezing, out of direct sun, and away from damp basements or unheated sheds.
Good
Not good
Heated basement that is dry
Damp basement
Utility room or closet
Unheated shed
Attached garage that stays above freezing
Detached garage that freezes
On a shelf or its caddy
On a wet concrete floor
In shade
By a sunny window
Store the dock and charger with it. They are electronics too.
What should you do with the charger and dock?
Unplug them. Do not leave a robot on charge all winter unless the manual says to.
Wipe them dry.
Coil cables loosely, without sharp bends.
Keep everything together so nothing is missing in May.
Surface skimmers such as the Betta SE, WYBOT F1 and Aiper EcoSurfer M2 come out before the cover goes on, and before ice. Rinse, empty the basket, dry, and store indoors. For battery level, follow each maker's manual.
What about robots with a dock at the pool?
Self-docking systems such as the WYBOT S3 and Beatbot AquaSense X have a station on the deck. Bring the robot and the station in for winter unless the manual says the station can stay out. Empty and rinse the station's debris bin first.
At what water temperature should the robot come out?
Check your manual for the operating range. As one example, Aiper lists a water temperature range of 50°F to 95°F for the Scuba 800. When your water is heading below your model's lower limit, the season is over for the robot even if the pool is still open. More in how cold is too cold for battery robots.
What are the common mistakes?
Storing it wet. Mildew and corrosion.
Storing it empty. Deep discharge can ruin the battery.
Leaving it in the shed. Freezing damages batteries and makes plastics brittle.
Leaving it in the pool under the cover. Months in winter chemicals with no charging.
Losing the charger.
Skipping the last clean. The pool opens green.
What should you do in spring?
Inspect brushes, tracks and seals.
Charge fully.
Check for app or firmware updates.
Refit a clean filter.
Run a first cycle and watch it.
If something is worn, order parts before the season starts. We list filters, baskets and chargers for many models in parts and accessories.
What if you are buying a robot in fall?
It is a reasonable time to choose, with no rush. If you buy now, run it before closing, then store it as above. Check the warranty start date: makers count from the date of purchase. Aiper warrants the Scuba X1 Pro Max for 3 years and the Scuba N1 Plus and N3 for 2 years. Beatbot covers the main body for 24 or 36 months depending on the model.
What is the short version?
Last clean after balancing the water. Rinse. Dry fully. Charge to the storage level in the manual. Indoors, dry, above freezing. Dock and charger with it.

Frequently asked questions
Should I run my pool robot before closing the pool?
Yes. Beatbot recommends a full cycle near the end of the closing routine, after balancing the water and before lowering the level, adding winterizing chemicals and covering.
Can I leave my pool robot in the pool over winter?
No. Take it out, clean and dry it, and store it indoors above freezing.
What charge level should a pool robot be stored at?
The level your manual recommends for storage. Beatbot says not empty and not left at a random level.
Can I store a pool robot in the garage?
Only if the garage stays dry and above freezing. Beatbot advises against unheated sheds and damp basements.
Do I need to dry the robot before storing it?
Yes. Rinse the filters and exterior, then let every part air dry so no moisture is sealed inside.
When should a pool robot come out of the water?
Before the water drops below the operating range in your manual. Aiper lists 50°F to 95°F for the Scuba 800.
