We'll need some additional information.

Pool type, size, water temp, age of the unit, has it ever had service, how long has it been tangling itself, has it always done this?

One of the 1st things to look at are the hose swivels. Sometimes they get jammed up.

Had the pool and cleaner since July. Yes it has always done this. Seems to be worse over that last couple of months though. I empty the bag when necessary. This is my pool...

If the hoses are the right length, make sure its running straight. The manual is pretty good and if you follow it you should be able to fix it.

Water temp please. Also, check the swivels. Is the jet stem pointing strait, slightly elevated, or slightly down?

Is the whip whipping a lot or is it gently swaying?

Is the backup unit functioning?

Are the floats evenly spaced?

IMHO, the connection in the wall may be in the wrong spot. I think it should have been put a couple feet from the shallow skimmer towards the deep end on that hump. That seems to be about the 1/2 way point of the pool's length. Or is it and the water is distorting my view? It looks like it might be plugged in near the deep skimmer.

It's actually connected just past the black overflow grate on the right side, very close to the middle of the pool. Water temps are in the upper 60's. We're in Southeast Texas. I did check my jet direction the other day, and I think that may be one issue. It is directed at about a 45 degree angle to the left if you are looking at the cleaner from the rear. I'll have to go over my manual to figure out how to adjust that if that's what I need to do. I did read in the manual that you can adjust it for different "goals", so I didn't know if the builder did that intentionally or not.

Make it straight back.

If the whip isn't gently swinging and swaying left, right, left, etc, the stainless thumb screw back there can be opened a bit. If it's moving quickly, then close it a little.

Bet that solves it if the swivels are a swiveling!

I'm betting its moving to fast. Too much pressure going to it will tangle it up every time.
At the wall fitting there is a knob you can turn to bypass some water back into the pool. Try loosening it a turn or so. The Polaris should move slowly, gently around the pool. If this doesnt help, read the manual regarding speed adjustment.
On the other hand, if you bypass too much water the cleaner will not have the power to pull out loops in the hose. The manual shows how to adjust the speed, you will need a watch with a second hand.

mike is probably onto something. I don't like turning the knob he's speaking of. They have a habit of breaking.

What color disk is in the threaded fitting in the wall? You will need to unscrew it to see. It will be evident as soon as you pull it out,

You should have had 3 that came with the unit. A red, black and blue. Each disk has an orifice that is a slightly different size. A smaller orifice is called for. The larger ones are used for longer hose lengths.

I've never seen a black restrictor, they have always been red and blue? The wheel rpm should be between 28-32. Its all in the first couple of pages of the manual.
