How to Fix a Vacuum Cleaner That Won't Suck

Careful inspection can find the objects clogging your vacuum's suction path.

A vacuum cleaner that won't suck is virtually a useless appliance. It doesn't mean that the vacuum cleaner is completely broken, however. Sometimes the fix is a matter of general maintenance dealing with filters and full canisters. Other fixes require a deeper inspection of the suction pathways in order to find the clogging culprit. Regardless, you may not need to send your vacuum cleaner for professional repair. You can fix your vacuum cleaner won't suck.

Things You'll Need

• Household tools
• Dishwashing soap (optional)
• Pipe cleaner

Instructions

1. Unplug your vacuum. Turn it over and look into the main suction port for any obstructions. Reach inside the port with your hands, if possible, or with a pipe cleaner to see if you can feel any objects or large dust balls possibly clogging the suction path.

2. Detach the hose attachment from the vacuum cleaner using your household tools if needed. If you have a flexible attachment, stretch and retract the hose to loosen any objects. Look inside one end for daylight to the other to ensure there are no other objects inside.

3. Inspect the hose attachment connection port on the vacuum for obstructions. Do a hand check and pipe cleaner check as step 1 shows.

4. Empty the vacuum cleaner's canister or bag completely. If they are filled to the brim, they can significantly reduce your vacuum's suction power. Inspect the suction path connections for any damage or obstructions. Replace any torn bags, as the tear can also reduce suction power.

5. Remove and wash all the vacuum's filters per the owner's manual instructions. Washing usually requires cold water and mild dishwashing soap. Check inside the canister for a removable filter. Replace both the canister and filters after emptying and cleaning.

Tips & Warnings

• If you don't have a pipe cleaner, consider using a wire coat hanger to feel for obstructions.

• A dirty roller brush may also reduce the suction power if there are strings preventing it from pushing dirt into the suction path.
