The installation process is straightforward, primarily involving connecting the hose sections to the cleaner head and then to your pool's suction point (skimmer or dedicated vacuum port).
Operating
The SandShark utilizes an exclusive SmartTrac programmed steering system to navigate your pool. This system allows the cleaner to maneuver effectively around tight corners, ladders, and other obstacles, ensuring fast and thorough cleaning performance. It is designed to clean faster than random-style cleaners, minimizing the chance of missing spots on your pool's surfaces.
The cleaner operates by moving across the pool floor and walls. For optimal performance, it is crucial to adjust the suction power correctly. The product includes a suction gauge with a yellow indicator to assist with this adjustment. If the suction is too high, the SandShark may lift or 'jump' out of the water. Adjust the suction until the indicator is within the recommended range for consistent operation.
Maintenance
Proper maintenance ensures the longevity and efficiency of your SandShark pool cleaner. The hoses should be stored flat and straight when not in use to prevent bending or kinking, which can affect the cleaner's movement and performance. It is also recommended to remove the cleaner from the water when shocking your pool to protect its components from harsh chemicals.
Troubleshooting
If your SandShark cleaner is not performing optimally, consider the following:
- Poor Cleaning Performance or Getting Stuck: Ensure the suction power is correctly adjusted using the provided suction gauge. Incorrect suction can cause the cleaner to move erratically, miss spots, or get stuck.
- Hose Kinking: Check the hoses for any bends or kinks. Hoses should be stored flat and straight when not in use to maintain their shape and allow for smooth operation.
- Inability to Climb Walls: Verify that the pool pump is running at an adequate speed and that the suction is properly adjusted. Some pool designs with very steep steps or walls may not allow the cleaner to climb completely.
