A cleaner going in circles is an indication of a problem with the drive mechanism on the same side as the unit turns. If cleaner uses drive belts, check them for tension or wear. If direct drive, it may be either the drive linkage or a damaged/worn impeller. Unless your are confident with repairing the unit yourself, this is a job for an experienced pool equipment technician. You can still troubleshoot the problem by running the unit on its side in shallow water and observing the relative drive speeds on each side.

My Polaris 3900 Sport is on it's side. I turn it back up on all 3 wheels and it hits the side of the pool and goes back on it's side again...going in circles.


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.

Cleaner not staying on bottom, its goes in circles but never reaches bottom


Check your wheel RPM and make sure that it is not more than 32. If the pool cleaners RPM are too high, it can cause the wheels to lose contact with the bottom of the pool. Make sure that the back up valve is cycling and working properly. If it is in the incorrect position, it could be thrusting the cleaner upward and away from the bottom. You may also need to adjust the water flow diverter to make sure that you are not receiving too much water.

My Polaris 3900 Sport Pool Cleaner's doing tight circles in the pool because the single left-side wheel is not turning at all, while the 2 right wheels are turning normally. How do I fix it?


I had a similar issue. When I lifted the unit out of the water while it was operating only the single wheel was rotating. I turned it off and removed the bag and hose. I flipped it over on a workbench and unscrewed the three recessing screws securing the base plate. Once the plate was removed I noticed the metal chain driving the two wheels had come off on the far side of the inner sprocket. I worked the chain back onto the sprocket and tested it by rotating the single wheel and verifying the other two wheels rotated. After reassembly I put the unit back in the pool and it drove straight and high on the sides. Hope this helps someone :-)

Polaris 3900 is going in circles


If the cleaner is running in circles to the left the chain has come off the double side. To fix take bottom off and place chain where it is riding on the center sproket. To test turn one wheel and all wheels should turn. Also on the axel blocks the wheels are attached to can be adjusted to allow more tension on the chain.

Make sure the wall screen is clean. It sounds like you are missing the wall fitting screen. If this is the case you have debrie in the unit and it has plugged the water management system. Take the cover off the head and clear all the jets where the hoses connect.

Hayward pool cleaner just goes in circle


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.

Cleaner goes in circles only.


could be a symptom of one of the "feet" or "pods" not being as tight as the other one.... when you pull off the wings...(carefully) take a flat head screwdriver and pop those small .5" caps off the pods.... take a .25 nutdriver and tighten both pods... if that doesnt work you may need a new aframe kit for the navigator. navigators are notorious for too many moving parts creating problems
