How to clean your vacuum.
Or just give your vacuum a good scrubbing. Because I have a dog that sheds like crazy, I vacuum almost daily and our vacuum after a while begins to smell. You know you turn on the vacuum and you smell your stinky dog.
I figured out long ago I really had to scrub the vacuum to get rid of the odor.
First, if you have a canister type like mine, take it all apart. I could never get this filter clean with scrubbing or running water so I decided to wash it in the washer. I fill with hot water and detergent and let it run on a gentle cycle. Really does a great job.
Just run it through a whole cycle and rinse.
