Part 1. Why Is My Pool Vacuum Not Getting Good Suction?

Several factors can contribute to poor pool vacuum suction. Understanding these factors helps you in knowing how to increase pool vacuum suction. Some of these include:

  • Issues with the Pool Pump: Problems such as a damaged impeller or air leaks in the pump can disrupt the vacuum's ability to create suction.
  • Congested Skimmer Basket: Debris buildup in the skimmer basket can obstruct water circulation, affecting the vacuum's performance.
  • Clog at the Intake Hole of the Pool Cleaner: Large debris or objects can block the intake hole on the pool cleaner, diminishing its capacity to collect dirt and debris. 
  • Leaks in the Vacuum Hose or Connections: Leaks can occur due to wear and tear, reducing the vacuum's efficiency over time.
  • Dirty or Clogged Filter: Accumulated debris in the filter can limit water flow, impacting the vacuum's suction power. Regular maintenance is essential to prevent clogs.

Check and Address the Blocked or Cracked Pool Hose

Many times, a blocked or cracked pool hose can significantly hinder your pool vacuum's suction power. Therefore, it's essential for you to identify and address this issue. Here are the steps for that:

pool hosepool hose
  1. Turn off the pool pump before inspecting the hose.
  2. Examine the entire hose for blockages, such as leaves or debris.
  3. If blockages are found, disconnect the hose from the vacuum head and the skimmer or dedicated vacuum line.
  4. Use a garden hose or pressurized water source to flush water through the hose to dislodge and remove debris.
  5. If the hose is flexible and has cracks, consider using a hose repair kit per the manufacturer's instructions.
  6. For rigid PVC hoses with cracks, it's often best to replace the damaged section or the entire hose.
  7. Reattach the hose to the vacuum head and the skimmer or dedicated vacuum line.
  8. Turn on the pool pump and observe the vacuum's performance to ensure improved suction.

Clean Your Pool Filter

A pool filter is a crucial component of your pool's circulation system and is responsible for keeping the water clean and clear. Its primary function is to trap and remove debris, dirt, leaves, and other contaminants from the pool water. However, if the pool filter becomes dirty or filled with rodents and leaves, it may affect the suction power of your vacuum. Here's how to increase pool vacuum suction by cleaning your filters:

  1. First, ensure the pool pump is switched off to avoid any accidents during the cleaning process.
  2. Depending on your pool's filtration system, locate and access the filter. This may involve removing a filter lid or opening a filter compartment.
  3. Take out the filter elements, which could be cartridges or diatomaceous earth (DE) grids, depending on your filter type.
  4. If you have a cartridge filter, rinse the cartridges with a hose to remove debris. If you have a sand or DE filter, follow the manufacturer's instructions for backwashing to clean the filter media.
  5. While cleaning, inspect the filter elements for any damage or signs of wear. Replace them if necessary.
  6. Once cleaned and inspected, reassemble the filter elements and ensure they are correctly seated.
  7. Restart the pool pump to resume normal filtration operations.
  8. Keep an eye on the pool water over the next few hours to ensure that water clarity improves as the filter does its job.

Remove Skimmer Basket Blockage 

Removing skimmer basket blockage is another method that helps answer your how to increase pool vacuum suction question. The skimmer basket captures leaves, debris, and other contaminants before they sink to the pool's bottom. However, this basket can become clogged over time, impeding water flow and affecting vacuum suction. Here are the steps to remove the skimmer basket blockage:

  1. Ensure the pool pump is switched off to avoid accidents during cleaning.
  2. Locate and access the skimmer basket. This typically involves removing the skimmer lid or cover.
  3. Carefully lift the skimmer basket out of its housing, wearing a pair of gloves to protect your hands from debris and dirt.
  4. Empty the contents of the skimmer basket, removing all leaves, debris, and other materials that may have accumulated. Dispose of this waste properly.
  5. Rinse the skimmer basket thoroughly with a hose to ensure it is clean and free from any remaining debris.
  6. Establish a routine cleaning schedule for the skimmer basket to prevent future blockages. Regular maintenance helps maintain optimal water circulation and filtration.
  7. For added prevention, consider using a pool skimmer sock. This fine mesh sock fits over the skimmer basket and captures smaller debris, reducing the frequency of blockages.

Replace the Pool Pump O-Ring

The pool pump plays a crucial role in the vacuum suction process, as it creates the necessary flow to move water and debris through the cleaning system. When there's an issue with the pool pump O-ring, it compromises this critical function. To address this problem, replace the faulty O-ring with a new one. Here are the steps for that: 

replace the pool pump O-ringreplace the pool pump O-ring
  1. Turn off the power to your pool pump.
  2. Slowly open the pressure relief valve on the filter canister until water dribbles out and the pressure gauge drops to zero.
  3. Unlock and lift off the filter head from the filter body.
  4. Remove the O-ring from the groove in the filter head collar.
  5. Clean the O-ring groove with a wet cloth.
  6. Install the replacement O-ring, coating it with silicone-based grease for sealing.
  7. Ensure the O-ring is correctly seated in the groove and the filter head is positioned with the gauge facing outward.
  8. Lock the filter head to the filter body by rotating the locking knob.
  9. Restore power to your pump from the circuit breaker.
  10. Observe the pressure relief valve until water sprays out, then close it by turning it clockwise.

Clean the Clogged Pool Pump Impeller 

The pool pump impeller is the pump's most important and only moving part. Dirt and debris accumulation doesn't allow water to flow smoothly through the cleaning filters, reducing vacuum suction. So, the best thing you can do regarding how to increase pool vacuum suction is to clean the clogged impeller. The steps for this are:

  1. Switch off the pump at first.
  2. Open the pump lid and remove the strainer basket.
  3. Use a screwdriver to reach the pump housing and locate the impeller hole.
  4. Scrape and move the screwdriver in and out to extract debris, and you are all done!
