How To Check For Vacuum Leaks

Learning how to check for vacuum leaks can save you both time and money from having to purchase a brand new vacuum. A leak in a vacuum can be very inconvenient. Leaks can cause a loss of suction power that can make cleaning a floor an extremely difficult task. There are a few simple steps you can take to check for a leak in your vacuum and fix the problem so you can get back to cleaning in a short amount of time.

To check for a leak in your vacuum, you will need:

  • Phillips screwdriver
  • Flathead screwdriver
  • Duct tape
  • Rubber cement
  • Replacement vacuum bag


  1. Thoroughly inspect the vacuum. Remove the bag from the vacuum and inspect it for holes. A leak in a vacuum bag can cause a drastic loss of suction, so this can be the easiest fix. Make sure there is nothing inside the vacuum hose.
  2. If you are not able to locate a leak in the vacuum bag or a blockage in the hole, use a screwdriver to take apart the vacuum. The process of taking apart the vacuum will allow you to see the tubing within the unit in order to check for a crack. There may be many small parts and screws, so be sure to put them in a safe place during the repair process. Start from the agitator of the vacuum and inspect the tubing. There will be several stops in the hose at different points of attachments. Gently pull the hose around the areas of attachment to ensure they are properly connected. Once you locate the leak, fixing it is rather simple.
  3. All you will need to fix a leak in an attachment area is rubber cement. If the leak is at a place of attachment, simply remove the hose from the attachment and coat the end with rubber cement. Place the tube back into the attachment. The leak will be fixed when the cement dries. You may choose to wrap a coat of duct tape around the attachment area to add more security to the area.
  4. If the leak is somewhere along the tubing, you will need duct tape to repair it. Simply locate the leak in the hose and wrap duct tape securely around the opening. You may feel the need to apply several layers of duct tape, which is perfectly acceptable.
  5. After you locate and fix the leaks in your vacuum, reassemble the parts you previously removed. Be sure to replace all of the parts and screws back into their original place. Doing so will ensure your vacuum is back to its secure structure.

Checking for a vacuum leak does not have to be done at the point of completely losing suction. Periodically vacuuming baby powder or another powder product will allow you to see if there are any leaks forming in the vacuum before the leaks become a more serious problem.
