How to Vacuum Your Inground Swimming Pool

July 5, 2024 Written by: Nick Luisi

Keeping your inground pool sparkling clean is essential for summertime fun. Regular vacuuming is a key part of that process, and it doesn’t have to be a chore! Here are some top tips and information to make vacuuming your pool a breeze:

Why Vacuum Your Pool?

Regular vacuuming is crucial for several reasons:

  • Clean Water: Removes dirt, leaves, and other debris that can cloud your pool water.
  • Prevents Algae: Helps prevent algae growth by removing organic material that algae feed on.
  • Maintains Chemical Balance: Reduces the need for excessive chemical adjustments by keeping the water clean.
  • Prolongs Equipment Life: Keeps your filtration system running smoothly by reducing the load of debris.

Types of Pool Vacuums

There are different types of pool vacuums, each with its own advantages:

  • Manual Pool Vacuums: Require manual operation but are effective for thorough cleaning.
  • Automatic Pool Vacuums: Operate independently and include suction-side, pressure-side, and robotic vacuums.
  • Robotic Pool Vacuums: The most advanced option, these vacuums clean the pool floor and walls and sometimes even scrub the waterline.

Preparing Your Pool for Vacuuming

Before you dive in, follow these preparation steps:

  • Turn Off Your Pool Pump: This will prevent debris from getting circulated through the filter system while you vacuum.
  • Remove Large Debris: Skim the pool surface to remove large objects that could clog the vacuum.
  • Brush the Pool Walls and Floor: Loosen dirt and algae to ensure a more effective vacuuming process.
  • Gather Equipment: Attach the vacuum head to the telescoping pole and connect the hose to the head.

Vacuum Setup

Proper setup is crucial for effective vacuuming:

  • Prime the Hose: Submerge the vacuum head and hose in the pool. Hold the other end over a return jet to fill the hose with water, removing air to ensure proper suction.
  • Connect to Skimmer: Insert the end of the hose into the skimmer suction port, ensuring a good seal. Depending on your pool setup, you may need to remove the skimmer basket and use a vacuum plate adapter.

Inground Pool Vacuum Technique

Vacuuming Technique

Now you’re ready to vacuum like a pro:

  • Start at the Shallow End: Begin vacuuming at the shallow end and move slowly toward the deep end.
  • Use Long, Slow Strokes: Move the vacuum head in overlapping lines to ensure you cover the entire pool floor.
  • Pay Attention to Corners and Steps: Debris tends to accumulate in these spots, so take extra care when vacuuming these areas.
  • Empty When Needed: For heavily soiled pools, you might need to pause and empty the pump strainer occasionally to maintain suction.

Filtration Settings

Choose the right setting for your filtration system:

  • For Light Debris: Use the “Filter” setting on your multiport valve for regular maintenance.
  • For Heavy Debris: Switch to “Waste” to bypass the filter and send debris directly to the drain.


After vacuuming, follow these steps to keep your pool in top shape:

  • Clean the Filter: Regularly clean or backwash your pool filter to maintain optimal suction and water clarity.
  • Check for Missed Spots: Inspect the pool for any missed areas and clean them if necessary.
  • Brush for a Finishing Touch: Consider attaching a brush to your telescoping pole and scrubbing the floor and walls for an extra layer of clean.

Bonus Tips

  • Schedule Regularly: Vacuum your pool at least once a week during peak usage season, and more often if there are a lot of trees or debris around.
  • Use a Pool Cover: When not in use, a pool cover can reduce debris accumulation.
  • Consider Automation: For a hands-off approach, explore automatic or robotic pool cleaners.

Troubleshooting Common Issues

  • Weak Suction: Check for air leaks in the hose or connections and clear any clogs in the vacuum head or hose.
  • Clogs or Blockages: Inspect the vacuum hose and filter for blockages.
  • Leaks: Inspect the vacuum hose and connections for signs of damage or wear.
