Professional cleaners know that a timesaving secret is to vacuum every floor in the house, including bathrooms and the kitchen. It's the fastest and most efficient way to pick up dust, hair, and all the little bits of debris that like to hide in corners.

In large private homes, the housekeeper usually supervises maids and other cleaning personnel. A cleaning lady is someone who comes in at scheduled intervals to do cleaning such as mopping, vacuuming, and dusting. The less sexist term is "cleaner."
