Smelly Vacuum Cleaner: How to Get Rid of These Bad Smells?
Does your vacuum cleaner smell bad? Fortunately, there are ways to fix it. Cleaning your vacuum cleaner can help keep the unit in good condition and prevent bad odors from forming. Schedule cleaning every three to six months.

Replace the dust bag or clean the dust bin. If your vacuum cleaner has a dust bag, try replacing it with a new one first. If your vacuum cleaner has a dust bin, remove it and wash it thoroughly with hot water, soap, and a little white vinegar or baking soda.

Wash or replace the filter. If your vacuum cleaner has a washable filter, clean it and rinse the filter with cold water until the water runs clear. It may take longer than five minutes. Let the filter dry for 24 hours before vacuuming again. If your vacuum cleaner has a replaceable filter, replace it every six to 12 months. If you have pets, you should probably replace the filter every six months.
Flush the plumbing. One easily overlooked source of odor is the plumbing. Debris can get stuck there and start to smell bad. To clean the hose: First, remove it from the vacuum and push a broom handle through it to remove large debris. Next, fill a sink with about four inches of hot water. Add a tablespoon of dish soap and two tablespoons of bleach or baking soda and vinegar. Place the hose in the sink and twist it to clean the inside. Then, empty the sink and run clean water through the hose to rinse it out. Hang the hose up to 1/2 inch of water.
