When in operation, it tends to leave the bottom of the pool and swim around in the 'air'. When not in operation, it sits with the rear end off the bottom of the pool. If I take it out and throw it back in the pool, it sinks very slowly. The result is that it does not do a good job of cleaning the bottom, and almost every day manages to tie itself in a knot around the hose connection at the side of the pool.

All air is out of the unit. I can see it, there's no air going through the line. I've played around with the float, tail pressure, position of the rear propulsion control to no avail. In any case, the problem is evident when the unit is OFF. I've played around with this, and there no tension on the floats when the unit is on the bottom of the pool.

I can hold the hose under the water while the unit is on the bottom, and it still doesn't have all wheels on the 'ground'. This is operating normally - no water flow when it's supposed to be between backup cycles. I've tried adding weights took it apart and put them inside, hung weights on various appendages, etc.

My last guess is the following: I have a salt water chlorinator, so there's a lot of salt in the water. I think that would make the unit more buoyant. But if so, I would expect to see some chatter on the internet from others with similar problems.

Maybe I'm missing a part, though this is hard to imagine? Any ideas would be appreciated! Thanks, Jerry. DBfan In The Industry. Aug 7, near the swamp. It's what gives the unit balance.

I have a customer who's Polaris is doing the exact same thing, but it will work for a short time. This is what we tried: 1 cleaned out the backup valve it was stuck partially open all the time.

Next thing we will do in the spring is open it up and check for blockages in the jets, check the gears Mod Squad. TFP Expert. Platinum Supporter. In The Industry. Apr 1, 34, Sebring, Florida. It comes from the factory heavier than water so it seems the only way to get it lighter than water is to put some air in it. Christian Platinum Supporter. Jul 19, Sacramento, California. This issue can be caused by water getting inside the head float.

If there is any water at all inside the head float it throws off the buoyancy. Christian said:. Vanya water in the head float throws off the buoyancy which can cause the exact symptoms he is describing in the OP. Check the filter screen in the Quick Disconnect and clean, if necessary. Clean the skimmer basket, pump basket, and pool filter. Check all of the hoses, connections, and swivels for leaks that cause loss of water pressure.

Polaris only turns in one direction. Make sure feed hose is floating. Sweep hose is sucked into the vacuum tube. Make sure the opening at the end of the sweep hose is not blocked by the sweep hose scrubber. Adjust the sweep hose to a gentle sweeping motion. Sweep hose sprays too much water out of the pool. Adjust the speed of the sweep hose by tightening the adjustment screw. Replace the sweep hose scrubber if it is worn or missing.

Add a sweep hose weight Part No. B2 to keep the sweep hose from spraying. The Cleaner does not clean the entire pool. Verify that feed hose reaches within 6" of the farthest point of the pool. If not, order a new hose section from your Polaris dealer.

Check the thrust jet for straight back position that optimizes random turning. While the cleaner is operating, hold it upside down and look into the vacuum tube. There should be two distinct, even jets of water. The cleaner is running in circles on its side.

Check the filter bag, if full it can weigh the cleaner down on one side. Remove the head float and shake it. If there is water in the float, order a new one. Check the hose floats to make sure they are spaced evenly. The wheels rotate less than 28 times a minute. Use the Polaris pressure tester to check the booster pump pressure. Check that the metal pre-filter is present and not clogged.

Make sure that the hose weight adjustment nut is screwed down correctly. Make sure the hoses have been cut as indicated in the instructions. Make sure that the blue reducing disk has not been installed in the quick disconnect.

Check that the booster pump is working normally. Clean the skimmer baskets, sand filter, and pump basket. Makes sure to mark the position of the sweep hose adjustment screw with a marker before removing it. How to Adjust the Thrust Jet on a Polaris Remove the unit from the water: Shut off the pool pump system and lift the Polaris vacuum unit out of the water, lifting it by its hose.

Moving the jet nozzle on a Polaris pool cleaner affects how it moves in the pool. Test the Polaris: Lower the Polaris by the hose back into the pool. This is an added maintenance cost. A robotic pool cleaner would be expected to last between 3 to 5 years and may last up to 8 years. There would be no replacement of parts.

Polaris Leans to One Side. If the head float develops a crack that allows water to fill the float, it gets heavy and the cleaner will run on its side. How do I fix Polaris backup valve? How to Troubleshoot a Polaris Backup Valve Run the swimming pool and lift the portion of the Polaris house containing the backup valve out of the water.

Shut the pool off and unscrew the backup valve body to disassemble it. Spray the backup valve mechanism with water from a water hose to clean debris off of it. Place the mechanism in the backup valve case. How do I know which Polaris pool cleaner I have? The newer Polaris cleaner models have the serial number stamped on a sticker on the back of the cleaner.
