My polaris 9550 pool cleaner wheels only spin on one side

SOURCE: Pool cleaner only goes in circles; doesn't clean the whole pool

could be a number of problems. The most common problem is the turbine bearings have failed. You will have to disassemble it to check them. A fix is a turbine kit with A-frames. This kit has all the moving parts excluding the turn valve. If your cleaner is going around in circles and twisting the hose, its likely you have a bad bearing or so on either the turbine, a-frames or both.

Check all of the following. Ones of these issues is probably causing your pool cleaner to go in circles. Let me know if these soultions don't work and I will be glad to offer more solutions, but I a think one of these might solve your problem:

1. You might not have proper water flow. Too much or too little pressure will cause this to happen. Check the pressure with your flow gauge and adjust if necessary.

2. Check for a partial blockage of the navigator throat. If you have a blockage, it could disrupt the movement of your cleaner. Clear blockage if necessary.

3. Check the shoes and wings. Damage or wear to them can disrupt your patterns of cleaning. If you notice that your shoes or wings are worn, replace them to correct the problem.

4. Check to make sure that your hose is not twisted. It should be clear of kinks, twists, and knots. Untangle if necessary. Laying the hose out in the sun will make it more pliable and easier to untangle if you need to do this.

5. Other things that could cause steering issues: check and clean the rear screen, check to see that the cone gear is is free and rotates smoothly, clean/replace/repair gear box, check pod connection, and check turbine and spindle assembly.

Hope this helps! Let me know if you need clarification or additional help!

If these automatic pool cleaners are moving in circles, it is usually an obstruction in the connection hose. Check the hose to make sure that there are not any knots or kinks that might not be immediately visible. Also, check to make sure that you don't have a partial blockage in either the cord or the throat. You will also want to check the return to make sure it is not allowing too much water to get to the cleaner. You might need to adjust the rear tension flap. Too much tension could cause the cleaner to go in circles. Finally, make sure that the wings and shoes are properly installed.

Check your wheel RPM. With these automatic pool cleaners, you can manually adjust the RPM. Low RPM could be the cause of the problem. To check the RPM, first mark a single wheel side tire, Turn the pump on, hold the cleaner under water and count the wheel revolutions for one minute. If the RPM is less than 28, you might need to remove the blue restrictor disk from the UWF or adjust the gate valve on the booster pump. Also, this may sound simple, but make sure there is no debris lodged in the wheels/axles. Check your filter screen in your in-line filter and make sure that it is clear of debris. You will also want to check your hoses, connections, and swivel to make sure that there are no leaks.

With these automatic pool cleaners, if they are not staying firmly on the bottom of the pool, it is most likely that there is air in the appliance casing.Try submerging your cleaner. Keep the cleaner vertical while you are putting it in slowly to let the air out. Ensure the unit sinks to the bottom of the pool.
