The head float provides the balance for the pool cleaner to perform it tasks such as moving, climbing, turning. Without this float head, the cleaner would not be able to climb the walls or steps and would be weighed down (lay down) to the pool surface. troubleshooting tip if the cleaner is weighed down or operating abnormally could mean that the float head is leaking or cracked. This will cause it to fill with water making it ineffective and needing to be replaced.
