What to do if your vacuum cleaner is loosing suction

Troubleshooting Guide: Restoring Suction Power for Your Vacuum Cleaner


A loss of suction in your vacuum cleaner can be frustrating, but before you rush to replace it, there are several steps you can take to restore its suction power. Here’s what you can do if your vacuum cleaner is losing suction.

Check the Filters

The most common culprit of reduced suction is a clogged or dirty filter. Depending on the type of vacuum you have, there may be multiple filters that need to be regularly cleaned or replaced. Refer to your vacuum’s manual for specific instructions on how to access and clean the filters.

Clear the Hose and Brush

Inspect the hose and brush for any obstructions such as hair, debris, or foreign objects. Use a long, flexible item such as a broom handle or a straightened wire hanger to dislodge any clogs.

Empty the Canister/Bin

If your vacuum has a bagless design, ensure that the canister/bin is not full. Even if it’s not at capacity, emptying it more frequently can help maintain optimal suction power.

Check for Blockages

Inspect the vacuum cleaner’s tubes and ducts for potential blockages. Use a flashlight to aid in detecting any blockages, and remove them carefully using a long, thin object like a straightened coat hanger or a pipe cleaner.

Assess the Brush Roll

If your vacuum has a brush roll, check it for any tangled hair or debris that may be hindering its rotation. Use scissors or a seam ripper to carefully cut away any entangled materials.

Examine the Belt

In upright vacuums, a worn or broken belt can cause a loss of suction. Refer to your vacuum’s manual for instructions on how to access and replace the belt.

Clean the Vacuum Head

The vacuum head itself may be obstructed with debris. Use a damp cloth or brush to clean the brush roll and remove any debris from the head.

Check the Seals

Inspect the seals and gaskets to ensure they are properly in place and not damaged. Damaged seals can result in loss of suction.

Seek Professional Service

If the above steps do not resolve the issue, it may be time to seek professional servicing. A certified technician can diagnose and resolve more complex issues with your vacuum cleaner.


By following these steps, you can potentially restore your vacuum cleaner’s suction power without the need for costly replacements. Regular maintenance and cleaning can go a long way in preserving the performance of your vacuum cleaner.
