Keeping your pool sparkling clean can feel like a constant battle, and when your pool cleaner stops working, it’s a real bummer. Many people, especially those new to pool care, find that figuring out why their automatic pool cleaner isn’t doing its job can be a bit confusing. Don’t worry, though!
Most common pool cleaner problems have simple fixes. We’ll walk you through the steps to get your cleaner back in action quickly.
Common Pool Cleaner Problems And Simple Fixes
Your automatic pool cleaner is a workhorse. It saves you tons of time. But sometimes, they just don’t work right.
This can be frustrating when you want a clean pool. Let’s look at the most common reasons your pool cleaner might be acting up and what you can do about it.
Understanding Your Pool Cleaner Type
First, know what kind of cleaner you have. This helps a lot when troubleshooting. There are a few main types:
- Suction-side cleaners: These connect to your skimmer and use your pool pump’s suction to move around and collect debris.
- Pressure-side cleaners: These hook up to your pool’s return line and use water pressure to move and clean. They often have a debris bag.
- Robotic cleaners: These are self-contained units that plug into an outlet and have their own motor and filter. They don’t rely on your pool pump.
Knowing your type helps because the fixes can be different for each.
Troubleshooting Suction-Side Pool Cleaners
Suction-side cleaners are very popular. They are usually straightforward. Here are common issues and how to fix them.
No Movement or Slow Movement
This is a big one. If your cleaner isn’t moving or is barely crawling, something is blocking its path or its suction. Let’s check the usual suspects.
Check the Hose
The hose is like the cleaner’s lifeline. Make sure it’s connected securely to the skimmer. Look for any kinks or twists in the hose that might be stopping the water flow.
If you find a kink, straighten it out. If the hose is old and brittle, it might have small holes or cracks. These can reduce suction.
You might need to replace sections of the hose or get a new one.
Skimmer Basket
Your skimmer basket needs to be clean. If it’s full of leaves and gunk, it blocks water from getting to the cleaner. Take out the skimmer basket and empty it.
While you’re at it, check the larger pipe that goes down from the skimmer. Sometimes big things can get stuck in there.
Cleaner Head Obstructions
Turn off the pool pump. Pull the cleaner out of the water. Check the head of the cleaner.
Are there any leaves, twigs, or other debris stuck in the mouth or under the wheels? Clean any obstructions you find. Sometimes, the wheels might be worn down or clogged, preventing it from gripping and moving properly.
Clean the wheels or check if they need replacing.
Inlet Valve Adjustment
Many suction-side cleaners have an adjustable valve where the hose connects to the skimmer. This valve controls how much water goes to the cleaner. If it’s set too low, the cleaner won’t get enough power to move.
If it’s set too high, it might not be able to move effectively. Experiment with adjusting it. You want enough water flow to make it move, but not so much that it flies around wildly or gets stuck.
Pump and Filter
Your pool pump needs to be running at the right speed and your filter needs to be clean for good suction. If your pump is weak or your filter is clogged, the cleaner won’t get enough power. Check your pump’s pressure gauge.
If it’s too high, it’s time to clean your filter. Ensure your pump is set to the correct speed if it’s a variable speed pump.
Cleaner Stuck in One Spot
If your cleaner only goes in circles or gets stuck in a corner, it’s usually a hose or balance issue.
Hose Length and Weight
A hose that is too short can’t reach all areas of the pool. A hose that is too long can get tangled easily. Also, the hose can pick up air bubbles if there’s a leak or if the water level is too low.
These bubbles can make the cleaner act erratically. Make sure the hose is the right length for your pool and is free of air.
Balancing Floats
Some suction-side cleaners have floats that help balance them in the water. If these are not set correctly, the cleaner can tilt and get stuck. Check your cleaner’s manual for how to adjust the floats.
Troubleshooting Pressure-Side Pool Cleaners
Pressure-side cleaners are a bit different. They use the return water pressure.
No Movement or Weak Movement
If your pressure cleaner isn’t moving or is very slow, check these things:
Debris Bag
The debris bag on a pressure-side cleaner can get full. An overly full bag restricts water flow, which is what powers the cleaner. Empty the bag frequently.
Also, check the bag for any tears or holes. A damaged bag won’t work correctly.
Return Line Connection
Ensure the cleaner is connected to the correct return line. Some systems have a dedicated port for pressure cleaners. Make sure the connection is tight and there are no leaks.
Check the back-up valve if your cleaner has one; it helps the cleaner move when it gets stuck.
Water Pressure
These cleaners need a good amount of water pressure to work. Make sure your pool pump is running and that the filter is clean. Low water pressure from the pump will mean the cleaner won’t get enough power.
Check your pump’s pressure gauge. If it’s high, clean the filter.
Wheel and Tread Wear
Like suction cleaners, the wheels and treads on pressure cleaners can wear out. If they are worn, they might not grip the pool surface well, leading to slow or no movement. Inspect them for damage or excessive wear.
Troubleshooting Robotic Pool Cleaners
Robotic cleaners are independent and usually very reliable, but they can have issues too.
Not Turning On
This is the most basic problem. First, make sure the power cord is securely plugged into both the robot and the power supply unit. Also, check that the power supply unit is plugged into a working electrical outlet.
Test the outlet with another device to be sure.
Not Moving or Spinning in Place
If your robot isn’t moving or is just spinning its tracks, here’s what to do:
Filter Baskets or Canisters
Robotic cleaners have their own internal filter baskets or canisters. If these are clogged with debris, it can prevent the robot from moving properly. Remove the baskets/canisters, empty them, and clean them thoroughly.
You might need to rinse them with a hose.
Obstructions on Tracks or Brushes
Turn off the robot. Inspect the tracks and brushes. Leaves, twigs, or other debris can get lodged in them, stopping movement.
Carefully remove any blockages. Check that the tracks are properly on their rollers and not off track.
Motor or Impeller Issues
Less common, but sometimes debris can get into the motor housing or the impeller fan that creates suction. If you can see debris near the intake, try to remove it. If you suspect a motor issue, it might be time to contact the manufacturer or a repair service, as this is more complex.
Not Climbing Walls or Cleaning the Waterline
If your robot isn’t cleaning the upper parts of your pool:
Filter Clog
Again, a clogged filter is a common culprit. When the filter is full, suction is reduced, and the robot loses power to climb.
Worn Brushes or Tracks
The brushes and tracks are key for grip. If they are worn down, the robot will have trouble climbing. Check them for signs of wear and tear.
Worn parts might need replacement.
Surface Type
Some robots are better suited for certain pool surfaces. If you have very smooth or slippery tiles, it might be harder for the robot to get a good grip.
Power Supply Connection
Ensure the power cord is not causing any drag or tangles that might affect the robot’s maneuverability and climbing ability.
General Pool Cleaner Maintenance Tips
Preventing problems is easier than fixing them. Here are some tips to keep your pool cleaner running smoothly:
- Clean Regularly: Empty filter baskets (skimmer and cleaner’s own) often.
- Inspect Hoses and Cords: Look for kinks, cracks, or damage.
- Check for Wear: Periodically inspect brushes, wheels, tracks, and debris bags for wear and tear.
- Proper Storage: Store your cleaner out of direct sunlight when not in use.
- Follow Manufacturer Instructions: Always refer to your cleaner’s manual for specific maintenance and troubleshooting advice.
Frequently Asked Questions
Question: Why is my automatic pool cleaner not moving at all
Answer: This is often due to a blockage in the hose, skimmer basket, or the cleaner’s intake. It could also be low water pressure from your pool pump or a clogged filter. Check all these areas first.
Question: My pool cleaner moves but doesn’t pick up debris
Answer: This usually means there’s a suction issue or the cleaner’s debris bag/filter is full or damaged. For suction cleaners, ensure the hose is clear and the pump is running well. For pressure cleaners, empty and clean the debris bag.
For robots, check their internal filters.
Question: How often should I clean my pool cleaner’s filter or debris bag
Answer: It’s best to clean them after each use or at least once a week, depending on how much debris your pool collects. More frequent cleaning leads to better performance.
Question: Can I use my pool cleaner if the water level is low
Answer: No. Most pool cleaners, especially suction-side ones, need a proper water level to function correctly and avoid sucking air. Low water levels can also damage your pool pump.
Question: My robotic cleaner is making strange noises
Answer: Strange noises often indicate debris caught in the motor, impeller, or tracks. Turn off the cleaner immediately and inspect it for any lodged objects. If the noise persists after cleaning, there might be a motor issue requiring professional attention.
Final Thoughts
Most pool cleaner problems are simple to fix. By checking hoses, filters, and looking for debris, you can get your cleaner back to work fast. Regular checks and cleaning help prevent many issues.
Keep your pool equipment running well and enjoy a clean pool all season long.
