I knew my vacuum had a problem the day my living room smelled worse after I cleaned it than before. The machine was pushing out a warm, musty smell with every pass. It was not the carpet. It was the vacuum.

Vacuum smell usually comes from one of three places: a clogged filter, a full bag or bin, or debris stuck somewhere it should not be. All three are fixable in under an hour.

Empty and Wash the Bin

Start with the obvious. Empty the dust bin outside, not over the kitchen trash can. Then rinse the bin with warm water and a drop of dish soap. Let it dry completely before putting it back, because moisture in the bin will make the next batch of dust smell like wet dog.

The Filter Is Usually the Culprit

Most vacuums have a washable filter, usually foam or pleated paper. Check your manual for how yours comes out. Foam filters can be rinsed and air dried. Paper filters cannot be washed, so replace them when they get gray.

I set a calendar reminder to wash my filter once a month. It takes five minutes and honestly, the suction improves too.

Clean the Brush Roll and Hose

Hair wraps around the brush roll and traps dust, which then bakes into a smell. Cut the hair off with scissors, careful not to cut the bristles.

The hose can hide surprises. A sock, a LEGO, a pet toy. Detach the hose and shine a light through it. If you see anything, push it out with a broom handle or a long screwdriver.

The Baking Soda Sprinkle

For a quick refresh between deep cleans, sprinkle a little baking soda on the carpet before vacuuming. It pulls odors out of the fibers and leaves the vacuum smelling neutral instead of dusty.
