Frequently Asked Questions

Why isn’t my Onga HammerHead moving or why is it moving sluggishly?
This usually indicates restricted water flow or an obstruction. Check the flapper chamber for debris, empty the skimmer and pump baskets, and ensure the filter is clean. Verify that the suction seal is installed correctly with the curved tips facing upwards. Use the flow gauge to confirm the cleaner is receiving the correct flow, and inspect the hose for blockages or air leaks.
Why is the cleaner getting stuck on steps or the pool ladder?
Redirect the return jets slightly downward or toward the problem area to guide the cleaner away. Confirm the hose length is correct, and reposition the hose weights as instructed in the manual. Adjusting the regulator valve to increase or decrease flow within the recommended range may also help.
Why does the HammerHead follow a repetitive or circular pattern?
A repetitive pattern occurs when the hose or water flow limits movement. Ensure the hoses are straight and not storing coil memory. Adjust the return jets downward and verify the hose weights are positioned correctly. Check that the regulator valve is free of debris and that the cleaner receives proper water flow.
Why won’t the cleaner climb the walls or stick to the surfaces?
Confirm the water flow is within the recommended range by testing with the flow gauge. Increase suction slightly if required. Check for worn footpads or a worn suction seal, and ensure the curved seal tips face upward. Clean the filter and pump baskets to restore proper flow. Note that square-bottomed pools with sharp wall angles may prevent wall climbing.
Why is the cleaner climbing out of the pool and sucking air?
Excessive suction or incorrect hose balance may cause the cleaner to rise too high. Ensure a regulator valve is installed in the skimmer and verify flow with the flow gauge. Check hose length, hose weight placement, and remove any debris from the regulator valve.
Why is the HammerHead tying itself in knots?
Knotted hoses usually indicate hose memory or excessive flow. Lay the hoses straight in the sun to remove coils, ensure the swivel on top of the cleaner rotates freely, and confirm the regulator valve and hose weights are correctly set. Re-test flow using the flow gauge.
Why is the cleaner leaving dirty patches or missing areas of the pool?
Check that the swivel rotates freely and the return jets are adjusted correctly. Confirm the hose length and hose weight placement. Straighten kinked hoses and inspect the footpad for wear. If using a timer, ensure the system is running long enough to complete a full cleaning cycle.
Why does the cleaner only clean the walls but not the floor?
This usually means the cleaner is receiving too much suction. Confirm the regulator valve is installed and adjust the flow using the flow gauge. Clear debris from the regulator valve and inspect the footpad for wear.
Why does the cleaner stick to the walls or floor and stop moving?
Reduce the suction slightly using the regulator valve and confirm the correct hose length and weight placement. Inspect the regulator valve for debris and ensure the footpad is not worn. Verify proper flow levels with the flow gauge.
Why is the cleaner not sitting flat on the bottom of the pool?
Check that a regulator valve is installed and operating correctly. Ensure the swivel is rotating freely, adjust the return jets downward, reposition the hose weights, and verify the overall hose length. Correct water flow using the flow gauge.
How do I ensure the correct hose length and proper balancing of hose weights?
Assemble enough hose to reach from the skimmer to the farthest point in the pool, plus one additional section. The first hose weight should sit between the 3rd and 4th hose sections, and the second between the 4th and 5th. Fine-tuning may be required depending on pool depth and water density.
How do I adjust water flow using the regulator valve and flow gauge?
Insert the flow gauge into the leader hose, switch on the pump, and adjust the regulator valve until the gauge indicator falls between the minimum and maximum markers. Remove the gauge after testing and reconnect the cleaner. Adequate flow is essential for random and complete coverage.
How do I install the Onga HammerHead correctly for my pool setup?
Backwash the filter, clean pump and skimmer baskets, and close other suction lines. Assemble the hoses, attach the suction seal, and connect the regulator valve to the skimmer. Test flow with the gauge, remove the gauge, and connect the cleaner. After starting the pump, the cleaner should begin pulsing immediately.
How do I maintain the Silent Flapper, suction seal, footpad, and hoses?
Periodically open the flapper chamber and remove debris. Inspect the suction seal and footpad for thinning or wear and replace when necessary. Keep hoses straight and stored out of direct sunlight, and avoid coiling them when not in use. Clean the regulator valve and filtration system regularly to maintain consistent performance.
Why is my suction seal or footpad wearing out, and when should I replace them?
These components naturally wear as they maintain contact with the pool surface. A worn seal can reduce random movement, and a worn footpad can affect traction and climbing ability. Replace both as soon as wear becomes visible or performance declines.
Can I leave the HammerHead in the pool all the time, including during chemical treatments?
The cleaner should be removed before any chemical shock treatment to avoid damage. When not in use, store the cleaner with the suction seal laid flat and the hoses uncoiled in a shaded area.
