Onga Hammerhead Hammer / Oscillator (Silent Flapper) - Genuine Spare Part K6130

Onga Hammerhead Hammer / Oscillator (Silent Flapper) – Genuine Spare Part K6130

Is your Onga Hammerhead pool cleaner stuck in the mouth or moving erratically? The culprit is almost always a worn Hammer (Oscillator). This single moving part is the heart of the Hammerhead's simple flapper design — and when it wears, the cleaner stops working properly.

What Does the Onga Hammerhead Hammer Do?

The Hammer (also called the Oscillator or Silent Flapper) propels the Hammerhead and BullShark pool cleaners around your pool. Unlike diaphragm-based cleaners, the Hammerhead uses just this one moving part — making it robust and long-lasting. Over time, however, the Hammer's shape changes with wear, causing it to jam in the cleaner's mouth and halt operation.

How Do I Know If My Hammer Needs Replacing?

• The cleaner is stuck in one spot or not moving
• The Hammer appears visibly deformed or flattened
• The cleaner moves sluggishly or in circles
• The Hammer is getting caught in the mouth of the machine
