Good-smelling vacuum

I've always had a problem with the vacuum exhaust stinking - probably because I've always had a dog. Our dog is an indoor dog who is very clean and gets regular baths and grooming, but it doesn't seem to keep my vacuum from stinking up the house when I use it. I've resorted to using a very inexpensive vacuum cleaner because replacing the filters is so expensive. Anyway, I heard a trick and tried it without much hope, but it's completely solved my stinky vacuum problem. Just stick a scented drier sheet in the bag (if it's bagless, you can throw it in the canister), and the exhaust will smell fresh and clean. It works tremendously. I am almost at the point of having to replace the bag again, and it still smells as fresh as it did the first time I used it. Nice!
