How to Fix a Hayward Navigator Pool Vacuum That Is Not Moving
The Hayward Navigator
A common pool cleaner is the Hayward Navigator, which consists of many moving parts. Occasionally, those parts fail and need to be replaced.
If you’re like me, you like to save money. Many pool stores will repair these cleaners with no “labor costs," but believe me, you will be paying more than enough for the parts and could save at least 50% or more by ordering the parts online and fixing it yourself.
You don’t need to be a rocket scientist to repair it. If you take the time to read through this article and refer to the photos, there really isn’t much to it.
Determining What Needs to Be Replaced
If your navigator seems to spin around in circles without really going anywhere, or if it doesn’t really move at all, or if you’ve owned it for a while, you probably already know that something may have gotten stuck in the unit. You need to pull whatever it is out. (Surprisingly, this problem accounts for around half the calls I get.)
Next, take the unit out of the pool and check the “shoes” or “feet.” These are the four pads that allow the cleaner to grip to the surface. If these are worn down too much, they will need to be replaced.
Checking the “A-Frame”
The A-Frame is inside the navigator, but I can usually tell if this is bad by how loose the pods seem to be. If there is a lot of play when you move the pods back and forth and it seems very loose, then the problem is likely to be the A-Frame. The is the most common repair I make on these cleaners and are easy to replace. The "pods" are usually not bad unless they are visibly cracked or broken. Other parts include the turbine, bearings, and gear box, which I will talk about shortly. A-Frame
Disassembling the Navigator
Please be sure to reference the photos for this section.
How to Disassemble the Navigator
- Remove the “wings” from the unit. The wings are attached to the pods.
- Pry off the round protector in the center of each pod, which will expose the screw heads. This will require a ¼ inch socket to unscrew.
- After removing the two ¼ inch screws, the pods may still be on tightly. Pry with a flat screwdriver on either side of the screw and work gently. Pods will come off.
- After pods are removed, turn the unit upside down and remove the center screw and remove the center piece, which that screw holds in. This will expose the turbine.
- Now remove the 4 Phillips screws as shown in the photo. This will remove the section that houses the A-Frame. Remove the A-Frame gently and set it aside.
- STOP! If the A-Frame is the only part that you are replacing, you will not need to go to the next step and remove the six perimeter screws. You can stop here and re-assemble the unit with the new A-Frame.
- There will now be six more screws around the perimeter of the unit. These are much longer than the first set of screws you removed. You will need to remove these to get to the turbine and bearings. Once screws are out, this piece will also be removed fully exposing the turbine and bearings. The bearings and turbine will lift out and the new bearing and turbine kit will go in its place.
- Lift the turbine and the two bearings out of place. Old bearings may fall apart. Don’t worry, the new ones won’t. Replace with the new bearings and turbine. They can only go in one way. Now replace the plate with the six screws. Turbine should spin freely.
The gearbox does not often need replacing. If it does, this is a very easy part to replace. With the six perimeter screws, turbine, and bearings out, simply pull out the old one and replace.
After replacing the parts, it is just a matter of re-assembling the unit just as it was disassembled. It's not difficult since there aren't too many screws to remove and put back in. If all was done right then it is ready to go back into the water and clean your pool!

Questions & Answers
I have had the Navigator for about two months, and its sucking, but not moving around the pool. Why is this?
If it's 2 months (brand new) it should be under warranty if there's something broken. Do the pods move back and forth when it's not on the bottom? I would also check for any obstruction in the turbine (a rock, large leaf, etc...) These rarely go bad when they are that new unless you bought it used. Also check valve positioning on the pool pump, meaning, does it have ENOUGH suction? If there's not enough suction, it won't move much.Helpful 22
One of the pods is jammed on my pool vacuum. How do I get it off?
If the pod is difficult remove, I usually use some wd-40 around it and a flat screw driver to work it off.Helpful 6
My Hayward pool vac wasn't moving so I replaced the A-frame and turbine kit. It now only stays in one section of the pool. No matter where I move it, it always makes it way back to the same section and does circles in that area. I replaced the gear box and medium turbine spindle gear last year but I assume its one of these. Do you have any suggestions?
The pods might need to be replaced. Where the pods fit on to the A-frame can become loose over time, allowing for a lot of movement. They should fit snug. Also, check the rubber shoes to make sure they aren't worn down.Helpful 17
All of the inner parts of my Hayward Navigator pool vacuum are new; the pods and shoes are new, the hose is new. When the Navigator is suspended the pods move. If I place the Navigator on the bottom of the pool all action stops. Do you have any suggestions?
The only suggestion I would have, knowing that you've replaced all the inner parts and pods, (otherwise, I'd say the A-frame or pods), would be to make sure there is enough suction through the cleaner. If you have a separate cleaner line, close the main drain valve and close the skimmer valve halfway and have the cleaner valve all the way open. Make sure filter is clean and the system has plenty of flow. More suction on the cleaner will make it work better. You can look at this article that explains how the valves should be set.Helpful 8
