Cleaner does not move but there is pressure going to the unit.
Verify the wheel RPM's are in range. If they are low or the wheels are not spinning then check the in-line filter for debris. If clear and the wheels still aren't spinning then check the water management system for clogs. If the RPM's are slightly below the prescribed range then remove the restrictor disc from the wall connector. If the wheels are moving too quickly then install the red restrictor disc.
Cleaner doesn't back up.
Hold the back up valve out of the water and verify that it cycles on and off. A complete cycle takes about three minutes. If it stays on all the time or doesn't come on at all then replace the back up valve.
Cleaner does not climb/goes in circles.
Verify that the wheel RPM's are in the correct range and adjust the thrust jet. If the cleaner isn't climbing well then ensure the thrust jet is in the 11 o'clock position. If it is going in circles then angle the thrust jet so it is pointing opposite of the way the cleaner is turning. For example, if the cleaner is turning right then point the thrust jet to the left.
Cleaner flies around the pool and/or does not make contact with the bottom of the pool.
1. Confirm that the blue restrictor disk is installed in the UWF® to decrease water flow. Or, install the red restrictor disk to decrease water flow even more.
2. Check the wheel RPM. If more than 32 RPM, unsrew the pressure relief valve to decrease water flow to cleaner. Note: The pressure relief valve should only be adjusted when a restrictor disk is installed.
3. Verify the back-up valve is cycling. Hold the valve out of the water and watch the jet. It should come on and go off.
Cleaner is sluggish, running with less power than normal.
1. Check the filter screen in the in-line filter and clean, if necessary.
2. Clean the skimmer basket, pump basket, and pool filter.
3. Check all of the hoses, connections, and swivels for leaks that could cause loss of water pressure.
4. Check the wheel RPM.
Cleaner only turns in one direction.
1. Adjust the thrust jet.
2. Make sure feed hose is floating.
Cleaner hangs up on steps or other obstacles longer than 3 minutes.
1. Check the wheel RPM.
2. Verify the back-up valve is cycling.
3. Adjust the thrust jet.
4. Remove unnecessary pool hardware or install a Ladder Guard Kit (order part #G21 from a Polaris dealer).
Hose(s) becomes tangled or coiled.
Check swivels and make sure they are spinning freely. Lay the hose out in the sun for 24 hours to eliminate any potential hose memory.

Sweep hose is sucked into the vacuum tube.
1. Make sure the opening at the end of the sweep hose is not blocked by the sweep hose scrubber.
2. Adjust the sweep hose to a gentle sweeping motion.
Sweep hose sprays too much water out of the pool.
1. Adjust the speed of the sweep hose by tightening the adjustment screw.
2. Replace the sweep hose scrubber if it is worn or missing.
3. Add a sweep hose weight (order part #B2) to keep the sweep hose from spraying.
The cleaner does not clean the entire pool.
1. Check the hose length reaches within 6" of the farthest point of the pool. If not, order a new hose section from your cleaner dealer.
2. Check thrust jet for 11:00 position that optimizes random turning.
3. While the cleaner is operating, hold it upside down and look into the vacuum tube. There should be three distinct, even jets of water. If there are not, contact Customer Service or a Polaris authorized Service Center for assistance.
The cleaner is running in circles on its side.
1. Check filter bag, if full it can weigh the cleaner down on one side.
2. Remove the head float and shake it. If there is water in the float, order a new one.
3. Check the hose floats to make sure they are spaced evenly.
The cleaner is tipping over/floating.
Verify the wheel RPM's are in range. Ensure that the head float is not filled with water. Try running the cleaner without the bag and if it fixes the issue then clean the bag with soap and warm water. This will remove any biofilm/oils that may have accumulated in the bag.
