Seeing your Polaris pool cleaner endlessly circle without properly cleaning the pool is frustrating. The random circles indicate issues preventing normal cleaner coverage.
The most common causes for a Polaris going in circles are clogs, debris jams, twisted hoses, flow problems, stuck wheels, and drive belt malfunctions.
By methodically checking each issue, you can isolate and fix the problem. This guide covers troubleshooting steps to get your Polaris cleaner back to efficiently scrubbing the entire pool.
Common Causes of Circular Movement
There are a few possible reasons why your Polaris pool cleaner might be going in circles. Here are the most common causes:
- Incorrect water flow: The most common reason for a Polaris pool cleaner going in circles is incorrect water flow. If there is too much or too little water flow, the cleaner will not be able to turn properly. To adjust the water flow, you will need to adjust the valve on the pool pump.
- Stuck randomizer ball: The randomizer ball is a small ball that is responsible for randomly turning the cleaner. If the ball is stuck, the cleaner will not be able to turn and will go in circles. To fix this, you will need to remove the randomizer ball and clean it.
- Obstructed hose: The hose that connects the cleaner to the pool pump can become obstructed, which will prevent water from flowing properly. This can cause the cleaner to go in circles. To fix this, you will need to inspect the hose for any kinks or blockages.
- Worn or damaged parts: Over time, the parts on your Polaris pool cleaner can become worn or damaged. This can cause the cleaner to malfunction and go in circles. If you suspect that there are damaged parts, you will need to replace them.
- Dirty or Worn Wheels: Accumulated debris, dirt, or general wear and tear on the wheels can affect the cleaner’s movement. Inspect the wheels for debris and clean them thoroughly. If the wheels are excessively worn, consider replacing them.
- Clogged Thrust Jet: The thrust jet, responsible for steering the cleaner, may be clogged with debris. Check the thrust jet for any clogs and clear them. Ensure that it moves freely and isn’t obstructed.
- Issues with Backup Valve: If your Polaris cleaner is equipped with a backup valve, malfunctions in its operation can lead to circular movement. Inspect the backup valve for proper function. If it’s not moving as intended, consider cleaning or replacing it.
- Imbalance or Misalignment: Imbalance or misalignment in the cleaner’s components, such as the wheels or float, can impact its trajectory. Check for any imbalance or misalignment issues in the cleaner’s components. Adjust or realign as needed.
Step-by-Step Resolution Guide
Step 1: Clean and Inspect the Wheels
- Remove the cleaner from the pool and inspect the wheels for debris or signs of wear. Clean the wheels thoroughly, and if necessary, replace them.
Step 2: Check the Thrust Jet
- Examine the thrust jet for any clogs or obstructions. Clear any debris and ensure the thrust jet moves freely.
Step 3: Untangle Hoses
- Straighten and untangle the hoses to eliminate any knots or kinks that may be causing the circular movement.
Step 4: Inspect the Backup Valve
- If your Polaris cleaner is equipped with a backup valve, check its operation. Clean or replace the backup valve if necessary.
Step 5: Address Imbalance or Misalignment
- Check for any imbalance or misalignment in the cleaner’s components, including the wheels and float. Adjust or realign as needed to ensure smooth movement.
Step 6: Confirm Adequate Water Flow
- Low flow levels prevent cleaners from properly regulating direction. Check that pool pumps provide 50-70 GPM flow when the Polaris runs. Consult your pump manuals and measure flow rates using a bucket to ensure optimal gallons per minute. Increase times or pump speeds as needed.
Step 7: Replace Faulty Parts
- For ongoing circulation despite clearing obstructions, faulty parts like flappers, tires, or drive motors need replacement to restore normal steering. Buy a rebuild kit to replace worn sprockets, flappers, and drive belts. New wheels and drive motors are available if those components fail.
Step 8: Adjust Cleaner Settings
- If a previously functioning cleaner starts circling suddenly, adjusting cleaner settings can help sharpen navigation. Consult your manual for optimizing things like wheel size, skimmer valve adjustment, and flow control orifices for your specific pool.
Preventive Tips and Maintenance
Keep your Polaris running straight by:
- Regular Cleaning: Clean your Polaris pool cleaner regularly to prevent the accumulation of debris that can affect its performance.
- Inspect Hoses: Periodically inspect the hoses for signs of wear or tangling. Replace any damaged hoses promptly.
- Check Wheels and Components: Regularly check the condition of the wheels, thrust jet, backup valve, and other components to identify and address issues early.
- Proper Storage: Store your Polaris pool cleaner properly during the off-season to prevent damage and wear on its components.
Proper maintenance keeps cleaners moving efficiently across every inch of pool surface for sparkling clean results.
Wrap-Up
While a circling Polaris cleaner can seem perplexing initially, methodically checking for obstructions, flow issues, worn parts, and settings usually reveals the underlying problem. Clear jams, replace damaged components, optimized cleaner adjustments, and professional service when needed will get your Polaris back to scrubbing your entire pool.
Common Queries
Why does my Polaris 3900 Sport go in circles or spirals?
Common causes include low water flow levels, clogged intakes, twisted hoses, worn drive belts/sprockets, stuck debris, or failing drive motors.
How do you know if a Polaris has enough water flow?
Consult pump manuals to confirm 50-70 GPM flow when cleaner runs. Use a bucket to measure gallons per minute if unsure.
What should you check first if a Polaris circles suddenly?
Inspect intakes, hoses, and moving parts for obstructions from debris like rocks or sticks that could send it off course.
How do twisted hoses cause a Polaris to circle?
Kinked hoses obstruct water flow to one side, so the cleaner favors the side receiving higher flow. Straighten hoses to maximize flow.
When should you call a technician for a circling Polaris?
If you’ve cleared all obstructions and replaced worn parts but it still circles, underlying mechanical problems likely need professional service.
