If your robotic pool cleaner seems to be losing suction or missing debris, it might be time to clean the filter. A clogged or dirty filter reduces performance, shortens lifespan, and puts extra strain on your cleaner. In this guide, we’ll show you how to clean your pool cleaner filter properly—whether it’s a Dolphin, Polaris, Hayward, or another brand.
Step 1: Power Down & Remove Cleaner
Unplug your robotic cleaner (if corded) and remove it from the pool.
Step 2: Open the Filter Housing
Most models have a top-load or side-load access. Follow the manual to pop open the casing.
Step 3: Rinse Filter with Hose
Use a garden hose to spray out debris and trapped particles. Avoid high-pressure nozzles that can damage the mesh.
Step 4: Deep Clean if Needed
Soak the filter in a 50/50 mix of water and white vinegar for 2–3 hours to break down oils and grime.
Step 5: Dry & Reinstall
Allow the filter to fully air dry before reinserting. Power your cleaner back on and run a test cycle.
🛠 Pro Tip: Clean After Every 2–3 Uses
In peak season, aim to rinse your filter every few uses, and deep clean it weekly. A clean filter means a cleaner pool—faster.
