How Can I Get Better Suction from My Pool Vacuum?

It can be really enjoyable to own a pool for swimming in the summer which creates a safe atmosphere and keeps people relaxed; however, cleaning it is very important to ensure that stress is reduced. Another beauty of a well designed and strategically placed pool vacuum is that it is one of the many things that pool owners always complain of bad suction from their pool vacuum. There may be a few issues when your pool vacuum is not as effective as it should be, and this can be aggravating. Here you will learn how to increase the suction on your pool vacuum so that you can keep pool clean without stress.

Understanding How Pool Vacuums Work

If the suction of the pool vacuum is still inefficient, it is crucial to have an idea of how your particular vacuum type works. Most pool vacuums operate through your pool’s filtration system. The vacuum is inserted into the pool’s pump and the pump then draws water and other objects through the vacuum head and hose. From there the water flows to the filter of the pool with the debris left behind to be cleared.

Any interuption of any of these steps leaves the vacuum with a reduced suction power. That’s why it’s important to consider all the features associated with the circulation and filtration systems of your pool.

Check for Clogs in the Hose

One of the simplest reasons for reduced suction is a clogged vacuum hose. Over time, leaves, dirt, or other debris can get lodged inside, blocking the flow of water. The solution is to disconnect the hose from both ends and check for blockages. Run water through the hose to flush out any obstructions. This should clear the path and restore better suction to your vacuum.

Inspect the Pool Filter

A clogged or dirty filter can also affect your pool vacuum’s suction. If the filter is full of debris, it restricts water flow, weakening the suction from the vacuum. To prevent this, make sure to clean or replace your filter regularly. If you use a cartridge filter, remove the cartridge and rinse it thoroughly with a hose. For sand or diatomaceous earth (DE) filters, backwashing the system can clear out debris and improve suction.

By ensuring your filter is clean, you'll improve water circulation and help your pool vacuum perform more efficiently.

Examine the Pump Basket

Your pool pump has a basket designed to catch larger debris before it reaches the filter. If this pump basket is full, it will restrict water flow and reduce the vacuum's suction power. Open the pump and empty the basket regularly. Even small amounts of debris can affect the system’s performance, so make this a habit, especially during pool season.

Look for Air Leaks

Air leaks can be a significant cause of reduced suction in pool vacuums. If air is getting into the vacuum hose or pool pump, it will disrupt the water flow. A common place for air leaks is the connections between the hose and the pool pump. Ensure all connections are tight and secure. If you suspect a leak but can't find it, turn off the pump and listen for hissing sounds, which can indicate where air is entering the system.

You can also check the pump lid for cracks or loose fittings. Replacing damaged parts can solve this problem and restore your vacuum’s suction power.

Prime the Vacuum Properly

If your pool vacuum isn’t primed correctly, it won’t work as efficiently. Priming ensures that no air is trapped in the hose, which could decrease suction. To prime the vacuum, fully submerge the vacuum head and hose in the water. Allow the hose to fill with water completely, then connect it to the skimmer or vacuum port. Once connected, the vacuum should work better without air bubbles interrupting the suction.

Ensure the Pool Water Level Is Correct

The water level in your pool can directly impact how well your pool vacuum works. If the water level is too low, the skimmer may suck in air instead of water, reducing the suction. Make sure your pool water level is high enough to keep the skimmer fully submerged. Typically, the water should reach about halfway up the skimmer opening.

Maintaining the correct water level ensures smooth circulation and better suction from your pool vacuum.

Keep the Pool Skimmer Clean

The skimmer basket collects debris before it enters your pool’s filtration system. If it’s overloaded with leaves or dirt, it can reduce suction by blocking water flow. Empty the skimmer basket regularly to ensure there’s no obstruction. This simple task can significantly improve your pool vacuum’s suction power and help maintain cleaner water overall.

Adjust the Vacuum Head

If the vacuum head isn’t adjusted correctly, it won’t create strong enough suction to clean your pool effectively. Make sure the vacuum head is positioned flat against the pool floor. If the head is tilted or lifted, the suction will be weaker. Some vacuum heads come with adjustable weights or height settings, allowing you to position them for optimal performance. Proper alignment will help the vacuum pick up debris more efficiently.

Clean or Replace the Vacuum Head Brushes

If your pool vacuum has brushes on the vacuum head, they can wear out over time, reducing the vacuum’s ability to pick up debris. If the brushes look worn or damaged, replace them. Clean the brushes regularly to remove any buildup of algae or dirt. Fresh brushes help the vacuum glide smoothly over the pool surface, improving its overall effectiveness and suction power.

Maintain the Pool Pump

Your pool pump is the heart of the entire system. Without it functioning properly, your pool vacuum won’t work as intended. Regularly inspect the pump to ensure it’s running at full capacity. If the pump motor sounds weak or is making unusual noises, it may need servicing or repair. Additionally, check the pump impeller for clogs, as debris can get stuck there and reduce suction.

A well-maintained pump will provide consistent suction for your pool vacuum, making the cleaning process much more efficient.

Replace Worn or Damaged Hoses

Pool vacuum hoses can wear out over time due to constant exposure to water, chemicals, and sunlight. If your vacuum hose has cracks, holes, or has become brittle, it’s time to replace it. Even small cracks can let air into the system, reducing suction. Invest in a quality hose that is designed to withstand harsh pool conditions for long-lasting performance.

Upgrade Your Pool Vacuum System

If you've tried all the above tips and still aren't getting the suction you need, it might be time to upgrade your pool vacuum system. Older or budget-friendly models may not have the power required for thorough cleaning. Consider investing in a more powerful pool vacuum that can handle your pool’s size and debris load. Robotic pool vacuums are another option, as they are self-contained and don’t rely on your pool’s pump for suction.

Regular Maintenance Is Key

Improving suction from your pool vacuum isn’t just a one-time task—it requires ongoing maintenance. Regularly check your pool's circulation system, clean out debris, and inspect hoses and filters to keep everything working smoothly. By staying proactive, you'll ensure your pool vacuum always operates at peak efficiency, giving you the clean, clear pool you want.

Conclusion

Getting better suction from your pool vacuum is about maintaining all parts of your pool’s filtration system. By keeping hoses clear, checking for leaks, cleaning the pump basket and filters, and making sure everything is primed and functioning properly, you’ll enhance the vacuum’s performance. With consistent care and maintenance, you can enjoy a cleaner pool with less effort, ensuring you get the most out of your pool vacuum.
