How to Store a Robotic Pool Cleaner: End-of-Season Guide

Why Storage Matters More Than You Think

Pool robot failures in years 2–3 are almost always due to improper storage — not wear from use. The three enemies: UV radiation, freezing temperatures, and residual pool water left inside the unit. Here's how to neutralize all three.

After Each Use

1. Remove from pool immediately. Don't leave it in the water "on standby." Remove it, every time.
2. Rinse with fresh water. Hose down the exterior and let the water flush through the filter housing.
3. Empty the filter. A damp filter left for days grows mold and degrades the mesh.
4. Store in shade or caddy. If your robot came with a storage caddy, use it. If not, store in a shaded location — never on concrete in direct sunlight.

End-of-Season Winterization

1. Run on a clean, empty cycle to flush the filtration system with fresh water.
2. Drain completely. Hold the unit at different angles to drain any trapped water. The pump housing can crack if water freezes inside.
3. Remove and clean filter cartridges. Soak in filter cleaner solution, rinse thoroughly, let dry completely before storing.
4. Lay cord flat. Don't store the cord coiled tightly — this creates permanent kinks. Lay it loosely in a figure-8 on the caddy or a flat surface.
5. Store above freezing. A heated garage, basement, or utility room. Temperatures below 32°F damage seals and can crack the pump housing.
6. Cover or bag the unit. Dust and rodents can damage drive tracks and filters during winter storage. A large garbage bag or dedicated cover works fine.

What Happens if You Ignore This

We've seen all of these in year-2 repair forums:

• Cracked pump housing from winter freeze — not covered by warranty, $150–$250 repair
• UV-degraded drive track rubber — tracks crack and detach, $60–$100 to replace
• Molded filter media requiring full replacement — $20–$40
• Permanent cord kinks causing intermittent power loss

Total cost of ignoring winter storage: $200–$400+ in repairs or early replacement. Total time for proper winterization: 20 minutes, once a year.
