According to the American Lung Association, vacuuming carpets and rugs at least three times a week is recommended. They also stressed that having the items professionally cleaned at least once a year amplifies the benefits more.
Note that there are three main benefits of regular rug cleaning. First, it eliminates trapped air pollutants such as pet dander, pollen, and house dust. Cleaning services eliminate the threat by using specially formulated solutions, and they also remove deep-seated dirt using high-powered vacuums.
