How To Get Rid Of Bad Odours In Vacuum Cleaners

Several factors can cause a foul-smelling vacuum, including:

• Dust & Dirt Buildup: Over time, dirt and debris accumulate inside the vacuum, causing a musty smell.
• Pet Hair & Dander: If you have pets, their fur and skin particles can create a lingering odour inside the vacuum.
• Mold & Bacteria Growth: Moisture trapped inside the vacuum can lead to mildew and bacteria, resulting in a stale or sour smell.
• Burning Smell From Belt or Motor: A burning rubber or electrical smell may indicate a worn-out belt or motor issue.
• Dirty Filters: Clogged filters filled with dust and allergens can start to emit an unpleasant odour.

How To Remove Bad Odours From Your Vacuum Cleaner?

1. Empty the dustbin or replace the vacuum bag

• If your vacuum uses a dustbin, empty it after every use and wash it with warm, soapy water to prevent lingering smells.
• If your vacuum has a bag, replace it regularly – especially if you vacuum pet hair or damp debris.

Tip: Add a teaspoon of baking soda or a dryer sheet inside the bag to keep your vacuum smelling fresh.

2. Clean or replace the vacuum filter

• Most vacuums have a HEPA filter or foam filter that traps dust and allergens.
• Check your vacuum’s user manual to see if the filter is washable or replaceable.
• If washable, rinse the filter under warm water, let it air dry completely, and place it back.

Tip: Replace vacuum filters every 3-6 months for best performance and odour control.

3. Wash the vacuum hose & attachments

• A clogged hose can trap dirt and bacteria, leading to foul odours.
• Detach the hose and flush it with warm, soapy water or a vinegar-water solution.
• Use a long brush or pipe cleaner to remove any stuck debris inside the hose.

Tip: Let the hose dry completely before reattaching it to avoid mold growth.

4. Check and clean the vacuum roller brush

• Hair, threads, and pet fur can get tangled around the vacuum brush roll, causing a musty or burning smell.
• Use scissors to cut away tangled debris and clean the brush with a damp cloth.
• For deeper cleaning, soak the brush in a vinegar-water solution for 10 minutes, then let it dry.

Tip: If the brush roll is worn out, replace it for better suction and odour control.

5. Deodorise with baking soda or essential oils

• Baking soda is a natural odour absorber – sprinkle a small amount inside the dustbin or vacuum bag.
• Add a few drops of essential oils (lavender, lemon, or eucalyptus) to a cotton ball and place it inside the vacuum bag for a fresh scent while cleaning.

Tip: Vacuum a small amount of scented baking soda on your carpets to help freshen up the vacuum.

6. Inspect the vacuum belt & motor for burning smells

• If your vacuum smells like burning rubber, the belt may be slipping or worn out.
• Turn off the vacuum, unplug it, and inspect the belt for cracks or damage.
• If necessary, replace the belt – it’s an easy fix that keeps your vacuum running smoothly.

Tip: If your vacuum smells like burning plastic or an electrical fire, contact a technician as this could indicate a motor issue.
