How can algae affect Hayward Navigator?

Answer 1

I assume that algae would affect the Navigator's ability to move on the bottom and/or climb walls because it is slippery. ---- The following is part of a Hayward troubleshooting guide:

My cleaner doesn't move Cleaners depend on several factors to make them operate. There must be enough water flow past the turbine. Use a vacuum gauge to measure the vacuum in the cleaner hose. You should have 1" vacuum per section of hose. Second, the four small "shoes" must be able to grip the pool surface. Make sure that the "shoes" are not worn out and that the surface of the pool is not slippery because of a buildup of algae. Note: some algae is clear, be sure to feel the underwater pool surface. Third, the shoes and "pods" must be working correctly. Any wear in the "drive train" can cause problems. To check for wear, hold the left and right "pods" in your hands and firmly, try to rock the pods. All force on the pods should be transferred to the turbine and no "play" should be evident. As a test, hold the cleaner by the hose. Keep the cleaner below water with the pump running. Hold the cleaner off the bottom of the pool and observe, the cleaner should: rotate right - not rotate - rotate left - not rotate - rotate right - etc. All the time, the "pods" should be kicking. If you can reach under the cleaner and stop the pods with your hand, there is either excessive wear on the internal parts or inadequate suction. Remember to check the vacuum reading before calling for assistance.
