If your Pool Cleaner is not moving or is barely crawling it may be clogged with debris. This guide describes how to clear the the debris and check the operation of the turbine that propels the pool cleaner.

Step by Step


Step 1

To gain access to the Main Turbine, remove the screw that secures the Access Cover Assembly to the Lower Body.

Step 2

Lift off the Access Cover Assembly.

Step 4

Reach into the chamber that holds the Main Turbine and clear out any debris.

Step 5

Spin the wheel of the Main Turbine to ensure that it moves freely. As you rotate the wheel you should see the pods move up and down. If they move, your cleaner should now operate properly.

Step 5

Replace the Access Cover Assembly and secure it with the single screw.

tonyeng - Sounds like you have covered most of the problems. The only thing I would suggest at this point is to up the pressure more. If you have the option, shut down most of the water flow going to the main drain while you are cleaning. If your cleaner is on a dedicated suction line, reduce the flow to the skimmer as well.

Hayward pool ultra vac goes very slow
1. have good pressure
2. replaced bearings
3. fully unassembled and made sure gears move freely, direction cap rotates freely
4. reassembled - ca not see any obstructions, feet going up and down, vac rotates right - straight and left as it should

but it goes very slowly. No idea.

any ideas please

GML - The bearings of the main turbine may be worn. Look at our guide on How To Service the Inside of a Hayward Navigator Suction Cleaner for information on replacing those bearings.

Done all that - the main turbine catches at a certain point and I need to exert a little bit more finger pressure to get it to turn. Remedy? Thanks

I had this same problem recently. I found that while re-assembling the pool vac, I had installed the turbine backwards, so its rotation was not sufficiently powerful. Look for Left (L) and Right (R) markings on the turbine and the pool vac, and make sure they match! It will make a big difference. BR
