Product Components

Your Rock&Rocker HJ3052 package includes the following:
- Robotic Pool Cleaner Unit
- Power Supply Unit
- 50FT Floating Swivel Cord
- Two Filter Baskets (pre-installed)
- User Manual
- Foam Pads (for optional extra flotation)

Setup
Initial Setup:
- Unpack the pool cleaner and all its components.
- Connect the floating swivel cord to the robotic cleaner unit.
- Connect the other end of the floating swivel cord to the power supply unit. Ensure a secure connection.
- Place the power supply unit at least 11.5 feet (3.5 meters) away from the pool edge. Use the included safety cord to secure it if necessary.
- Carefully place the robotic cleaner unit into the pool. Ensure it is fully submerged and air bubbles have escaped before proceeding.
- Plug the power supply unit into a grounded electrical outlet.
Important Considerations:
- Do not use the pool cleaner immediately after spraying chemicals in the pool.
- Do not use the cleaner as a dosing machine, as this may damage and corrode internal components.
- Ensure the pH value of the pool water is between 7.0 and 7.4 for optimal performance and longevity of the cleaner.
- If the unit is not climbing walls effectively, consider installing the provided foam pads for additional buoyancy.
Operating Instructions
Starting a Cleaning Cycle:
- Once the unit is fully submerged and powered on, press the 'CYCLE' button on the power supply unit to select your desired cleaning duration (1H, 2H, or 3H).
- The robotic cleaner will automatically begin its intelligent navigation to clean the pool floor, walls, and waterline.

The intelligent navigation system ensures thorough coverage of your pool.
Wall Climbing Function:
The HJ3052 is equipped with strong adsorption capabilities, allowing it to climb and clean pool walls effectively without falling. This ensures comprehensive cleaning beyond just the pool floor.

The cleaner adheres to pool walls for vertical cleaning.
Tangle-Free Operation:
The 50-foot floating swivel cord is designed to minimize tangling during operation, allowing the cleaner to move freely throughout the pool without interruption.

The swivel mechanism helps prevent the cord from tangling.
Maintenance
Cleaning Filter Baskets:
It is crucial to clean and wash the filter baskets every time after use to maintain optimal filtration performance.

The cleaner features two easily accessible filter baskets.
- Turn off and unplug the power supply unit.
- Carefully remove the robotic cleaner from the pool using its handle. Allow excess water to drain.
- Open the top cover of the cleaner.
- Remove the two filter baskets.
- Rinse the filter baskets thoroughly with a garden hose to remove all collected debris.
- Ensure the baskets are clean before reinserting them into the cleaner.
- Close the top cover securely.

Rinsing the filter baskets is a quick and simple process.
Storage:
Store the robotic pool cleaner in a cool, dry place, away from direct sunlight and harsh weather conditions, to prolong its lifespan.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Cleaner not moving properly or track off wheel. | Debris obstruction, track misalignment, or motor issue. | Check for debris in tracks/brushes. Realign tracks. If issue persists, contact customer support. |
| Power cord tangles frequently. | Excessive cord length in pool, or unit spinning in place. | Ensure only necessary cord length is in the pool. Unwind the cable every 2-3 uses. |
| Cleaner not picking up fine particles/dirt. | Filter baskets are full or mesh is clogged. | Clean filter baskets thoroughly after each use. Ensure no fine debris is bypassing the filters. |
| Cleaner gets stuck on drains or uneven surfaces. | Design limitation or insufficient buoyancy. | Ensure proper buoyancy (use foam pads if needed). The unit is designed to navigate most pool surfaces without issue. |
| Black marks left on white pool surfaces. | Friction from black rollers. | This is a known cosmetic issue for some users. Ensure rollers are clean. |
| Water found inside the cleaner upon arrival. | Product testing prior to packaging. | This is normal. All units are water-tested before shipment to ensure functionality. |
