Pool Vacuum Hose Question

If this question should be on a different group, please let me know; I don't want to create clutter here.
We have a Hayward Pool-Vac Ultra that is powered through about 35 feet of 1 1/2 inch (sections) hose. The hose is frequently twisted into loops that keep the vacuum from cleaning all of the pool. We have replaced the gear-box, but that didn't help. What we think would help is some kind of a swivel joint that could be placed between sections of the hose, but we have not been able to find any such coupling. Do any of you know of something like this, or do any of you have any other suggestions on what we can do to eliminate this hose looping?

(Australian-made) Kreepy Kraulelr successfully avoids this by a weight about three sections distant from the cleaning head.

That looks a lot like a Navigator. I have been nursing one along for 8 years now. They are maintenance hogs.
First be sure the consumables are OK (feet, flappers etc)
A swivel in the hose would defeat the whole purpose of the gear box. They use the hose to steer it. If you are going in one direction all the time (enough to twist up the hose) and the gear box seems to be working right look at the walking mechanism. You can test the gearbox by holding it just under the water by the hose and watching how it turns. You should go one way for a minute or so, then go the same amount in the other direction. If you verify the gear box is working check out the walking part. There should be very little lost motion as you rock the legs back and forth. Both sides should be equal. Two things to suspect are a bad roller on the cam followers or lost motion where the walking legs attach to the cam follower shaft. You can make that better for a day or so by tightening the screw but the real fix is replacing cam follower and the leg. I have had luck, simply shimming that joint with a piece of the clear plastic from a bubble package. (that thing you can't open without a weapon) Cut a piece the size of the flat on the shaft, line it up and shove it back together. Crank down on the screw. I am not sure how long that lasts but I am several months in.

pool and spa forum is a good place for these questions. Have you called Hayward tech support? Have a Polaris here which of course is driven by pressure from the returns, not suction, but uses a similar length hose though it's maybe 5/8". That hose does have swivels in it. Even that some times gets tangled up, but usually works well. I can see where a 35 ft hose that;s 1.5" with no swivels would be a problem.

Something's not right. I've had mine for about six or seven years, and never had that problem. Take it to another shop.

When I had mine rebuilt, I watched the guy. He took out the gearbox, and examined it carefully, scratched a few bits of stuff out, and proclaimed it good to go. He said that those that were heavily encrusted would be soaked in vinegar for a couple of days. As a last resort, I would try that. Plus look for the obvious. I have one, and many times when I would have trouble with it, the reason was something obvious I overlooked.

Steve, Thanks for your advice, I'll take another look at it, but after replacing the gear box and a bunch of other parts, I'm not sure that will be the answer. I asked Hayward the same question and received the answer below from one of their tech-reps.
"The cleaner is having a steering issue. Do what is called a hang test. Lift it up off the floor by the hose and watch it for 4 minutes. It should turn both directions, against the hose, a couple of turns and stop for a few seconds between directions. If it turns one direction only or doesn't turn, change the gear box.
"If it passes the test, youre looking at the A-frame and Turbine for the fix. The hoses are stationary so that the cleaner can turn against them. If one side is taking good steps and the other side is just vibrating, then look at the A-frame and Turbine AX621DAT Kit."
I'll try the suggested "Hang-Test" and see what happens and will let all know.
Lee PS: for the person above, I couldn't find my first post despite a thorough search for it, which is why I reposted it. SORRY!

There is an echo in here. I suggested the hang test several days ago and I also suggested checking for lost motion in the walking leg to A frame joint (probably where the problem is). That shaft has two flat spots and it, along with the matching hole in the feet, gets rounded out. If one is more worn than the other, it goes in circles. That kinks up the hose.

(S)he probably has a Navigator and twisting the hose is a common symptom caused by a bunch of problems, mostly worn out parts. You can buy a "kit" which is basically everything but the top and bottom cover for about $200 on Amazon and that will fix it for quite a while. Navigators are great pool cleaners but they are maintenance hogs. If you want to "piece at a time" it, be sure you have good shoes, the rocker arms are tight on the shaft and that the rollers on the wocka wocka are free with no flat spots. That is just the start tho.
