Understanding Why Your Pool Cleaner Goes in Circles: Causes and Solutions

If you’ve noticed that your pool cleaner seems to be stuck in a continuous circular pattern instead of effectively cleaning the entire pool, it can be frustrating and concerning.

Understanding the reasons behind this behavior is essential for troubleshooting and getting your pool cleaner back on track.

In this comprehensive guide, we will explore the common causes of a pool cleaner going in circles and provide you with practical solutions to rectify the issue.

Hose and Connection Issues

Twisted or tangled hose

Check the pool cleaner’s hose for any twists, kinks, or tangles. A tangled hose can impede proper movement and cause the cleaner to go in circles. Straighten out any kinks or twists and ensure the hose is properly connected.

Hose length adjustment

Evaluate the length of the hose in relation to your pool size. If the hose is too long, it can create excess slack and result in the cleaner getting stuck in a circular pattern. Trim or adjust the hose length as necessary to maintain proper tension.

Hose buoyancy

Incorrect hose buoyancy can cause the pool cleaner to tilt and veer off in circles. Ensure that the floatation devices on the cleaner and hose are properly positioned and functioning. Adjust or replace them if needed.

Pool Cleaner Wheel and Track Issues

Wheel obstruction

Inspect the wheels of the pool cleaner for any debris, rocks, or obstructions that may hinder their rotation. Clear any debris and ensure the wheels move freely.

Worn or damaged wheels

Over time, the wheels of the pool cleaner can wear down or become damaged, affecting their ability to move smoothly. Check the condition of the wheels and replace them if necessary.

Uneven wear on wheels or tracks

Uneven wear on the wheels or tracks can cause the cleaner to veer off in one direction, leading to circular movement. Regularly inspect the wheels and tracks for signs of wear and replace them if needed.

Water Flow and Pressure Issues

Inadequate water flow

Insufficient water flow can cause the pool cleaner to lose traction and go in circles. Check the pool pump and filter system for clogs, blockages, or reduced water flow. Clean or backwash the filter and ensure proper water circulation.

Adjusting water flow

Many pool cleaners have flow adjustment valves that regulate the amount of water flowing through the cleaner.

If the flow is too high or too low, it can affect the cleaner’s movement. Experiment with different flow settings to find the optimal flow rate for your specific pool cleaner.

Issues with the pool cleaner’s intake

The pool cleaner’s intake, such as the throat or vacuum port, may become clogged or restricted, leading to imbalanced water flow. Clean the intake and ensure it is free from debris or obstructions.

Pool Design and Obstacle Interference

Pool shape and corners

The shape and design of your pool can influence the movement of the cleaner. Pools with sharp corners, angles, or unusual shapes can cause the cleaner to get stuck or follow a circular path.

Adjust the hose length, consider alternative hose configurations, or use a different pool cleaner model better suited for your pool shape.

Obstacles in the pool

Objects such as pool toys, steps, or ladders can disrupt the cleaner’s path and cause it to go in circles. Remove any obstacles from the pool before running the cleaner to ensure uninterrupted movement.

Seeking Professional Assistance

If you have exhausted all the troubleshooting steps and your pool cleaner continues to go in circles, it may be necessary to seek professional assistance.

Pool experts and technicians can conduct a thorough assessment of your pool cleaner and identify any underlying issues that require repair or replacement.


A pool cleaner going in circles can be a sign of various issues, ranging from hose and connection problems to water flow and pool design considerations.

By understanding the causes outlined in this article and implementing the suggested solutions, you can rectify the circular movement of your pool cleaner and ensure it efficiently cleans your pool.

Regular maintenance, proper hose management, and addressing any underlying issues promptly will help maintain the effectiveness and longevity of your pool cleaner.
