It can be confusing when your pool cleaner isn’t working right. One common issue people wonder about is why is pool cleaner floating. This might happen because something is a bit off with the cleaner itself or how it’s set up.
Don’t worry, it’s usually an easy fix! We’ll walk through the simple steps to get your cleaner back to doing its job. Let’s figure out why it’s floating and get your pool sparkling again.
Understanding Why Your Pool Cleaner Floats
Seeing your pool cleaner bobbing on the surface instead of scrubbing the bottom is a common problem, especially for those new to pool maintenance. This usually means something is preventing it from staying submerged and effectively cleaning your pool. It’s not a sign of a major breakdown, but rather a puzzle to solve with a few straightforward checks.
The main reason a pool cleaner floats relates to buoyancy and the weight it carries. Pool cleaners are designed to be neutrally buoyant or slightly negatively buoyant so they sink and stay on the pool floor. If they start floating, it’s because their buoyancy has changed or something is lifting them up.
This can be frustrating, but the causes are generally simple and fixable.
Common Culprits Behind a Floating Pool Cleaner
There are a few key things that can make your pool cleaner float. We’ll explore each one to help you pinpoint the issue with your cleaner.
1. Air Trapped Inside the Cleaner
Many pool cleaners, especially robotic ones or suction-side cleaners, can trap air. This is a very common reason why is pool cleaner floating. When air gets inside the cleaner’s body or hoses, it makes the cleaner lighter.
Lighter objects float more easily, so the trapped air pushes the cleaner upwards.
How does air get trapped? For robotic cleaners, it can happen if the unit isn’t fully submerged when you turn it on, or if there’s a leak in the casing. For suction-side cleaners, it’s often due to air being pulled in through the suction line.
This could be from a loose connection, a damaged hose, or if the cleaner itself is not properly sealed against the pool floor.
To fix this, you usually need to bleed the air out. Robotic cleaners often have a specific process for this, like tilting them or running them briefly upside down. For suction-side cleaners, you might need to check all connections to ensure they are airtight and that the cleaner’s body is intact.
2. Insufficient Weight or Ballast
Some pool cleaners are designed with specific weights or ballast to help them sink and stay down. If these weights are missing, damaged, or have come loose, the cleaner might not be heavy enough to stay on the pool floor. This is particularly true for older models or those that have undergone repairs.
Check if your cleaner has removable weights. If so, ensure they are all in place and securely fastened. If the weights are integrated into the design, look for any signs of damage or detachment.
Sometimes, replacing a lost or broken weight can instantly solve the problem of why is pool cleaner floating.
3. Debris or Obstructions
Debris can play a surprising role in making a pool cleaner float. If debris gets lodged in the cleaner’s brushes, wheels, or internal mechanisms, it can disrupt its movement and balance. Sometimes, the debris can create a pocket of air, or simply make the cleaner unstable.
For example, a large leaf or a piece of plastic stuck in the impeller of a suction-side cleaner can cause it to work inefficiently and potentially float. Similarly, if a robotic cleaner’s brushes are clogged, it might not be able to grip the pool floor properly and could drift upwards.
Regularly cleaning out any debris from your pool cleaner is a simple preventive measure. If you notice your cleaner floating, check its brushes, wheels, and any accessible intake areas for obstructions. Clearing them out should help it return to normal operation.
4. Issues with the Hose or Connection (Suction-Side Cleaners)
For suction-side pool cleaners that attach to your pool’s skimmer or a dedicated vacuum line, the hose is critical. If the hose has leaks, cracks, or is not properly connected, it can suck in air. This air travels to the cleaner and makes it float.
It’s a very common scenario for why is pool cleaner floating when you have this type of cleaner.
Check the entire length of the hose for any signs of damage. Ensure that the hose is securely connected to the cleaner head and to your pool’s suction fitting. A loose connection at either end is a prime suspect for air leaks.
Sometimes, an old or brittle hose can develop small holes that are hard to see but are enough to let in air.
If you suspect a hose issue, you might need to
5. Problems with the Drive System or Impellers
The drive system is what powers the cleaner’s movement. For robotic cleaners, this involves motors and gears. For suction-side cleaners, it’s often the pool pump’s suction that drives them, and they might have impellers or turbines.
If the drive system is malfunctioning, the cleaner might not be able to maintain proper contact with the pool floor. For instance, if a motor on a robotic cleaner is weak or has a problem, it might not have enough power to stay down. With suction-side cleaners, a clogged or damaged impeller can reduce suction power, leading to the cleaner losing its grip and floating.
Diagnosing drive system issues can be more technical. If you’ve ruled out simpler causes like air or debris, it might be time to consult your cleaner’s manual or a professional for further assistance.
6. Buoyancy Control Issues (Robotic Cleaners)
Robotic pool cleaners have internal mechanisms for buoyancy. Some use floatation devices or adjustable components to ensure they stay at the right depth. If these components are damaged, misaligned, or have become detached, the cleaner can become too buoyant.
For example, some robotic cleaners have float arms or specific buoyant materials inside. If these break or fall out, the cleaner will definitely float. Refer to your robotic cleaner’s user manual for information on its specific buoyancy control features.
Sometimes, these parts are user-serviceable, but other times, professional repair might be needed.
7. Incorrect Cleaner Setup for Your Pool Type
Not all pool cleaners are suited for every type of pool. Some cleaners are designed for flat-bottomed pools, while others can handle slopes and steps. If you’re using a cleaner that’s not optimized for your pool’s shape or depth, it might struggle to stay grounded, leading to floating.
Also, consider the water level in your pool. If the water level is too low, it can affect the suction for suction-side cleaners or make it harder for robotic cleaners to stay submerged properly. Ensure your pool water level is at the recommended height, usually mid-skimmer.
Using the correct cleaner for your pool type and ensuring proper water levels are essential for optimal performance. If your cleaner is consistently floating, it might be a sign that it’s not the right fit for your specific pool environment.
Troubleshooting Steps When Your Pool Cleaner Floats
When you notice your pool cleaner is floating, take a deep breath. It’s a solvable problem. Follow these steps to diagnose and fix the issue:
- Turn Off The Cleaner: Always turn off and unplug or disconnect the power to your pool cleaner before attempting any adjustments or cleaning. Safety first!
- Check For Trapped Air: For robotic cleaners, consult your manual on how to release trapped air. This often involves tilting the unit or running it briefly out of the water. For suction cleaners, ensure the hose is fully submerged and all connections are tight.
- Inspect for Debris: Thoroughly examine the cleaner’s brushes, wheels, and any intake ports for lodged debris. Clean out anything you find.
- Examine Hoses and Connections (Suction-Side): Check the entire length of the hose for leaks or cracks. Make sure all connections are secure.
- Verify Weights/Ballast: If your cleaner has removable weights, confirm they are all present and properly attached.
- Clean Filter and Skimmer Baskets: A clogged filter or skimmer basket can reduce overall suction, indirectly affecting some cleaners.
- Check Water Level: Ensure your pool’s water level is at the correct height, usually mid-skimmer.
- Consult Your Manual: Your cleaner’s user manual is your best friend. It often has specific troubleshooting guides for common problems.
- Test Run: After making adjustments, turn the cleaner back on and observe its behavior. Make further adjustments as needed.
If you’ve gone through these steps and your pool cleaner is still floating, it might indicate a more significant mechanical issue. In such cases, contacting the manufacturer or a pool service professional is the next best step.
Frequently Asked Questions
Question: Why does my new pool cleaner float?
Answer: Even new cleaners can float if they trap air during their first use, or if a component isn’t seated correctly. Check your manual for the initial setup and air release process.
Question: Can a low water level make my pool cleaner float?
Answer: Yes, especially for suction-side cleaners. A low water level can lead to the skimmer pulling in air, which then travels to the cleaner and makes it float.
Question: How do I know if my pool cleaner has trapped air?
Answer: A pool cleaner that floats or bobs erratically on the surface is a strong indicator of trapped air. You might also hear gurgling sounds from the cleaner or its hose.
Question: What if my suction-side cleaner floats to the surface and won’t go down?
Answer: This usually means it’s sucking in air. Check the hose for leaks, ensure connections are tight, and make sure the skimmer basket isn’t clogged. Also, verify the cleaner itself isn’t damaged.
Question: Should I use a cleaner with weights if mine keeps floating?
Answer: Some cleaners come with adjustable weights to help them stay down. If your current cleaner consistently floats despite other troubleshooting, a weighted model or adding weights (if possible and recommended by the manufacturer) might help.
