As a cure-all that even our great-grandmothers used, place one bay leaf in the vacuum.

Advice from grandmother
Nothing to worry about, though; the plant is placed in the bag rather than the vacuum itself, so the tiny leaves won't clog the machine.
The versatility and adaptability of laurel make it an ideal substitute for scented candles, incense, and room sprays, among its many other uses around the house.
When we light candles or incense, the combustion process can make the air less healthful and can even leave a burning scent in the air even after we switch them off.
Laurel: That's exactly why the vacuum cleaner is the way to go.
In any case, if we put the bay leaf in the vacuum bag, the activity of the device will release its contents and aroma throughout every area of our house.
Since bay leaf, whether in the shape of leaves or a complete plant, can be purchased on the market for a few euros, we can clean and perfume our rooms without breaking the bank, and the scent will linger for a long time.
A pleasant, clean aroma will waft through your home as soon as you give this old remedy a go.
