3. Operating the Cleaner
The CX-300 is equipped with Smart Navigation to optimize its cleaning path. It can clean the entire pool, including the floor, walls, and waterline, or focus on specific areas based on the selected mode.

The device will automatically shut off once its cleaning cycle is complete or the battery is depleted. Use the included hook attachment with a standard pool pole for easy retrieval from the water.

4. Maintenance
Regular cleaning of the filter basket is crucial for maintaining optimal performance.
- Remove Filter Basket: Open the top lid of the cleaner and carefully remove the reusable debris chamber cartridge.
- Empty Debris: Dispose of collected debris into a trash receptacle.
- Rinse Filter: Use a garden hose to thoroughly rinse the filter basket. Ensure all fine particles and debris are flushed out. Rinse from the outside of the filter inwards to push debris out, rather than further into the mesh.
- Reinstall: Once clean, allow the filter to dry before reinserting it into the cleaner.
