Proper winterizing is one of the easiest ways to add years to your robot's life and avoid a nasty surprise at pool opening.
Clean and Dry Everything
Run one last cycle, then give the robot a thorough clean: empty and rinse the filters, flush out the impeller and housing, and let everything dry completely before storage. Trapped moisture and leftover debris can cause odors, mold, and corrosion over a long off-season. Our guide to cleaning pool robot filters covers the deep clean.
Store It Right
- Coil the cord loosely in wide loops to avoid permanent kinks and future tangling.
- Keep the robot and power supply on the caddy, off the ground.
- Choose a cool, dry, frost-free space out of direct sunlight — freezing temperatures and UV both damage components.
This is really an extension of the year-round habit of removing the robot after each cycle.
Never Leave It in a Freezing Pool
Do not leave a robot in a pool that will freeze — ice can crack the housing and ruin seals, and constant winter chemical exposure degrades it, as explained in can you leave your pool robot in the pool. Treated well, a quality robot like the Dolphin Sigma lasts many seasons; see how long a pool robot lasts.
