Operating Instructions
- Start Cleaning: Once the cleaner is fully submerged, press the power button located on the top of the unit. The cleaner will begin its automatic cleaning cycle.

Maintenance
- Retrieval: Use the provided retrieval hook to carefully lift the cleaner from the pool.
- Fast Drainage: As you lift the unit, its fast drainage system will quickly release water. Ensure all water has drained before removing it completely from the pool. This prevents debris from re-entering the pool.
- Filter Cleaning: Open the cleaner's housing and remove the dual-layer filter basket. Rinse the filter thoroughly with a garden hose to remove all collected debris, sand, and fine particles. Ensure both layers of the filter are clean.
- Reassembly: Once the filter is clean, place it back into the cleaner's housing and securely close the unit.
- Storage: Store the Lydsto S2 in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the unit is clean and dry before storage.

Troubleshooting
If you encounter any issues with your Lydsto S2, please refer to the following common troubleshooting steps:
- Cleaner not moving or starting:
- Check the battery level. Recharge the unit if the battery is low.
- Ensure no debris is obstructing the wheels or the suction inlet.
- Verify that the power button was pressed firmly to initiate the cleaning cycle.
- Poor cleaning performance:
- Clean the filter basket. A clogged filter significantly reduces suction power.
- Inspect the pool for any large debris that might be blocking the cleaner's inlet.
- Ensure the cleaner is fully submerged and has expelled all air bubbles before starting.
- Cleaner not parking automatically:
- Confirm that the battery level is sufficiently low to trigger the auto-parking feature.
- Check for any physical obstructions near the pool edge that might prevent the cleaner from docking correctly.
- Water not draining quickly:
- Ensure the cleaner is lifted completely out of the water for the drainage system to activate.
- Check for any blockages in the drainage ports that might impede water flow.
If these steps do not resolve the issue, please contact customer support for further assistance.
