    I'd do in this order:
    1. adjust (center) rear jet
    2. use hose screw to balance pressure between hose & jet
    3. check wheel bearings, (inside) gear tracks/guides for missing teeth & adjust tension appropriately
    4. adjust idler wheel to apply equal pressure to wheels & check swing axle function.

There are several things that may cause the unit to run in circles. #1 never roll the hose when the unit is out of the water. Infact every year you should remove the entire unit from the pool and lay the hoses straight on the deck in the warm sun light. 1 to 3 days is usually enough use rocks if you need to in order to force th hose to stay straight. the hoses have memory and when you roll them up and lay them outside the pool this starts the problem. you also need to see if all three wheels turn in sequence. you can grab ahold of the single wheel on the left side and be sure it spins forward and backward without resistance. additonally the right front wheel should spin at the same time. there is a gear that runs between both front wheels and when the booster pump runs the gears spin and turn the front wheels. the back wheel turns from the tension placed on it by the small wheel between the two tires on the right side. over time the metal gears can wear out the plastic grooves inside the large wheels. if there is too much wear on one of the wheels you can remove one of the front tires and swap it with the back tire since it does not need the gear or grooves to turn. another issue is the directional jet located under the fitting the whip hose attaches. this uses the water pressure to direct the unit in different directions if the nipple is pointed to 12 noon this causes the unit to climb more 6 am will limit the climbing the urge. when pointed to the left it cause the unit to vere to the right and vice verse. 808-871-POOL

Water comes out of the tail of polaris 360, but tail does not sweep.

check the filter in the wall of the pool where the Polaris line hooks up, it got a small filter in it. you are running it on low-pressure that's why it not sweeping, could also be a plugged impeller on the booster pump.

Polaris tail not sweeping. I believe the impeller on the booster is clogged restricting water flow

If unit is operating satisfactorily otherwise, the check end of sweep tail for missing orifice tip. Without it tail won/t sweep. Also check adjusting screw. Out - more tail flow In - less.

The tail of the Polaris comes out of the water surface some times and sprays a ten foot jet of water. I would like to weigh it down some more to prevent this but at the same time not limit its movement.

That is normal-- when polaris runs up the side and heads down the tail follows and there you have it. You know the saying if you cant stand the heat get out of the kitchen-- well if you cant stand getting sprayed stay in the kitchen. Just kiddin the kids seem to enjoy the machine spraying everybody

3900 goes round circles and stays in deep end

I had the issue of Polaris 3900 going in circles and staying on the deep end for a while before I figured out the problem.
In some cases the lone wheel connected directly to the gearbox turns faster than the wheels connected to the chain causing it to veer right because of slippage.

When this happens check to see if the chain is secure. It should be tight enough so that the tensioner does not touch the wheel sprocket. In my case I had to remove some 6 links from the chain and once I did this it started working well.

When you disassemble the unit you will see a sticker with a diagram of the drive chain on the feedpipe. Check that the angle of the tensioner is consistent with the diagram so that it does not touch the sprocket.

My polaris is doing circles. it appears the single wheel doesnt move like it used to

i've just discovered i have this same issue with my polaris 3900. the machine is less than 3 months old. there is a small metal "gear" in the wheel hub just behind the blue "hub cap". a single screw holds it on the axle. it appears that the gear has worn the out around the hub causing it to slip and not be able to drive the wheel.. it appears that the solution would be to buy another wheel.

My polaris runs but there is no suction. Any recommendation?

Inside the part where the bag clicks onto the large circle outlet on the top are two little valves. Sometimes these get clogged by algae. Use a thin wooden skewer to poke the algae through then replace your line hose onto the pool return. Everything should work now.
