Pool Cleaner Not Working Properly Fixes

It’s super common for pool cleaners to stop working right. You might be new to pool care and find it a bit tricky. Don’t worry!

We’ll walk you through simple steps to figure out why your pool cleaner not working properly and how to get it running again. Let’s find out what’s going on and fix it fast.

Why Is My Pool Cleaner Not Working Properly

So, your pool cleaner is being stubborn. This is a common problem, especially if you’re just getting started with pool maintenance. There are many reasons why a pool cleaner might stop doing its job.

It could be something very simple, like a blocked filter or a loose connection. Or it might be a bit more involved, like a worn-out part. When your pool cleaner isn’t working, it means dirt and debris can build up, making your pool look less than inviting.

This guide will help you pinpoint the issue without needing to be a pool expert. We’ll cover the most frequent causes and give you clear solutions so you can enjoy a clean pool again soon.

Common Pool Cleaner Problems and Solutions

Many things can cause your pool cleaner to stop working as it should. Let’s look at the most frequent issues and how to fix them. These steps are easy to follow and should help you get your cleaner back on track quickly.

Check the Power Source

First things first, is your pool cleaner getting power? This sounds obvious, but it’s often the simplest fix. For robotic cleaners, ensure the power cord is securely plugged into the transformer and that the transformer is plugged into a working outlet.

Check if the outlet itself has power by plugging in another device. Some units have a reset button on the transformer; press it if needed. For suction or pressure-side cleaners, make sure your pool pump is running.

If the pump is off, the cleaner won’t get the water flow it needs.

Inspect the Filter System

A dirty or clogged filter is a major reason for pool cleaners failing. When your filter is full of gunk, it restricts water flow. This means less suction for suction-side cleaners and less pressure for pressure-side cleaners.

Robotic cleaners can also struggle if the debris bag or filter canister is full.

For cartridge filters, remove the cartridge and clean it thoroughly.
For sand filters, perform a backwash.
For DE filters, clean or replace the DE grids.
For robotic cleaner bags or canisters, empty and rinse them out.

Examine the Pool Cleaner’s Intake and Debris Canister

Debris can get stuck in the cleaner’s intake or in its internal filter. This prevents water from flowing through and powering the cleaner.

Suction-side cleaners: Check the hose connections for leaks or obstructions. Ensure the vacuum head isn’t blocked by large leaves or twigs.
Robotic cleaners: Open the debris canister or bag. Remove any large items that are blocking the intake. Rinse the canister and its seals.

Look at the Filter Bag or Canister (Robotic Cleaners)

If your robotic cleaner has a filter bag or canister, a clogged one will stop it. Water can’t pass through effectively.

Empty the bag or canister.
Rinse it thoroughly with a hose.
Make sure it’s properly reinserted into the cleaner.

Check for Obstructions

Sometimes, the cleaner itself gets stuck or blocked.

Ensure the cleaner’s path isn’t blocked by pool ladders, toys, or large decorative items.
Check the cleaner’s wheels or tracks to make sure they can move freely.
Inspect the brush or rollers for tangled hair, string, or other debris that might be preventing movement.

Inspect the Hoses (Suction and Pressure-Side Cleaners)

Hoses can develop leaks, cracks, or blockages.

Suction-side: Look for any holes or tears in the hoses. Check that all hose sections are securely connected to each other and to the cleaner head. A leak anywhere will reduce suction power.
Pressure-side: Ensure the hoses are connected properly to the return jet and that there are no kinks. A loose connection here will mean water isn’t being pushed out correctly to drive the cleaner.

Examine the Impellers or Drive System

The impeller is like a small fan that pulls water through the cleaner or pushes it. If it’s blocked or damaged, the cleaner won’t move or clean.

For many robotic and some other types of cleaners, you can access the impeller by opening the debris canister.
Carefully check for any debris caught around the impeller.
Remove any obstructions gently.

Check the Pool Cleaner’s Brushes or Treads

Worn-out brushes or treads mean the cleaner can’t grip the pool surface to move and scrub.

Look at the brushes or treads. Are they significantly worn down?
If they look bald or have chunks missing, they may need to be replaced.

Is the Pool Water Level Correct?

This is especially important for suction-side cleaners. If the water level is too low, the skimmer might suck air instead of water. This starves the cleaner of the suction it needs.

Ensure your pool water is at the proper level, typically halfway up the skimmer opening.
Add water if necessary.

Consider the Age and Wear of the Cleaner

Like any machine, pool cleaners wear out over time. Parts can break or become less effective.

If your cleaner is old and you’ve tried all other fixes, it might be time for a replacement.
Check for cracked casings, broken parts, or general signs of heavy wear.

Troubleshooting Specific Cleaner Types

Different types of pool cleaners have their own common issues.

Robotic Pool Cleaners

Robotic cleaners are self-contained units with their own motor and filtration.

Not moving: Check the power supply, debris canister, and for any tangled cords or brushes. Ensure the motor area is clear of debris.
Not climbing walls: This can be due to a dirty filter bag/canister, worn brushes, or if the cleaner is designed only for the pool floor. Some models are not meant to climb.
Not picking up debris: This usually points to a clogged filter bag/canister, a blocked intake, or a weak motor (which could indicate an electrical issue or internal damage).

Suction-Side Pool Cleaners

These cleaners attach to your pool’s skimmer and use the suction from your pool pump.

Not moving or moving slowly: The most common cause is low water level, a clogged skimmer basket, a dirty pool filter, or leaks in the hose.
Not picking up debris: Check for blockages in the hose, skimmer, or cleaner head. Ensure the pool pump is running at the correct speed.
Making a banging noise: This often means the cleaner is stuck and repeatedly hitting a wall or obstacle, or it might be a sign of air in the line.

Pressure-Side Pool Cleaners

These connect to your pool’s return jet and use the water pressure from your pump to move and clean. They often have a debris bag.

Not moving: Ensure it’s properly connected to the return jet and that the return jet valve is open. Check for kinks in the hose. Make sure your pool pump is running at adequate pressure.
Not picking up debris: The debris bag might be full or torn. Also, check for any blockages in the cleaner’s intake or hoses.
Moving erratically: This could be due to a faulty sweep tail or if the cleaner is getting stuck on obstacles.

Maintenance Tips to Prevent Future Problems

Preventing issues is always better than fixing them. Regular maintenance will keep your pool cleaner working at its best.

Clean the filter regularly: This is the single most important maintenance task.
Empty the debris canister/bag: Do this after every cleaning cycle or at least every few days.
Check hoses for leaks: Repair or replace damaged hoses promptly.
Inspect brushes and treads: Replace them when they show signs of wear.
Store the cleaner properly: When not in use, store it out of direct sunlight and extreme temperatures.
Run the cleaner on a schedule: Don’t let debris sit in the pool for too long.
Check the water chemistry: Proper water balance helps prevent algae and other buildup that can clog cleaners.

When to Call a Professional

While many pool cleaner issues are DIY fixes, there are times when you’ll need expert help.

If you’ve tried all the common troubleshooting steps and your cleaner still isn’t working, it might be an internal motor issue or a more complex electrical problem.
If you’re uncomfortable opening up parts of the cleaner or dealing with its mechanics, it’s best to consult a pool service professional.
If your cleaner is under warranty, contact the manufacturer or the store where you purchased it.

Frequently Asked Questions

Question: My pool cleaner isn’t moving at all. What should I check first?

Answer: First, check that your cleaner is receiving power and that the power outlet or transformer is working. For suction or pressure-side cleaners, ensure your pool pump is running and the water level is adequate. Then, inspect for any obstructions around the cleaner, its hoses, or its debris filter.

Question: My robotic cleaner is climbing the walls but not cleaning the bottom. Why?

Answer: This often happens if the filter bag or canister is clogged, preventing proper water flow to clean the bottom. It could also mean the brushes are worn out and can’t scrub the floor effectively. Make sure the cleaner isn’t only designed for wall climbing.

Question: My suction-side cleaner isn’t picking up much debris. What’s wrong?

Answer: Check your pool’s skimmer basket for clogs, and make sure your main pool filter is clean. Also, inspect the cleaner’s hoses for any kinks, leaks, or blockages. Ensure the pool water level is high enough for the skimmer to function correctly.

Question: My pressure-side cleaner’s debris bag is always full very quickly. Is this normal?

Answer: While it’s normal to empty the bag regularly, if it fills extremely fast, it might mean there’s a lot of debris in your pool that needs to be skimmed manually first. It could also indicate a leak in the cleaner’s hose or a problem with the return jet connection.

Question: How often should I replace parts on my pool cleaner?

Answer: This depends on usage and your pool’s conditions. Brushes and treads might last a year or two with regular use. Hoses can last longer if they don’t develop leaks.

It’s best to inspect parts regularly and replace them when they show visible signs of wear or damage.
