4.2 Placement in Pool
Once fully charged, ensure the cleaner is powered off. Carefully place the cleaner into the pool. It will sink to the bottom. Ensure there are no obstructions in its path.
5. Operating Instructions
5.1 Starting the Cleaner
To begin cleaning, simply press the power button on the top of the unit. The cleaner will activate and begin its cleaning cycle automatically. No complex programming or syncing is required.
5.2 Cleaning Modes
The RERIOU Robotic Pool Vacuum offers three distinct cleaning modes:
- Floor Mode: Focuses cleaning on the pool floor, ideal for general debris accumulation.
- Wall Mode: Engages the wall-climbing function to clean the pool walls and waterline.
- Full Coverage Mode: Combines both floor and wall cleaning for a comprehensive clean of the entire pool surface.
Select the desired mode by pressing the mode selection button (refer to the product diagram for button location). The cleaner will adapt its navigation and cleaning patterns accordingly.

5.3 Stopping the Cleaner
The cleaner will automatically return to a reachable edge or float to the surface when its cleaning cycle is complete or the battery is low. Use the provided retrieval hook to safely remove the cleaner from the pool.
6. Maintenance
6.1 Cleaning the Filter Basket
Regular cleaning of the filter basket is crucial for maintaining optimal suction and cleaning performance. It is recommended to clean the filter after each use, especially if the pool is heavily soiled.
- Remove the cleaner from the pool.
- Open the cleaner's top cover to access the filter basket.
- Remove the filter basket.
- Empty debris from the basket.
- Rinse the filter basket thoroughly with a garden hose until all debris and fine particles are removed.
- Ensure the filter basket is completely dry before reinserting it into the cleaner.

6.2 General Cleaning and Storage
Wipe down the exterior of the cleaner with a soft, damp cloth. Do not use harsh chemicals. When storing the cleaner for extended periods, ensure it is clean, dry, and fully charged. Store it in a cool, dry place away from direct sunlight and extreme temperatures.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cleaner does not start. | Battery is low or depleted. | Charge the cleaner fully (approx. 3 hours). |
| Cleaner moves slowly or stops frequently. | Filter basket is full or clogged. | Clean the filter basket thoroughly. |
| Cleaner does not climb walls effectively. | Filter basket is full; water chemistry imbalance (algae). | Clean filter. Check and balance pool water chemistry. |
| Cleaner is not picking up debris. | Filter basket is clogged or damaged; suction intake blocked. | Clean or replace filter basket. Check for and remove any blockages from the suction intake. |
| Cleaner gets stuck. | Obstruction in pool; uneven pool surface. | Remove large debris. The track drive system is designed to handle most uneven surfaces. |
If the problem persists after attempting these solutions, please contact customer support.
