Sometimes a carpet is noticeably in dire need of a cleaning with obvious stains and grime. What you aren’t aware of, is how carpets are designed- to conceal dust and dirt deeply embedded within its fibers. Imagine the spills, germy soles, and buildup of filth that seep its way into your carpets. The deeply rooted dust which a vacuum won’t catch, will trigger allergies.
For a proper, clean environment, once a year is the recommended minimum to have your carpets cleaned. Area of heavy traffic, such as living rooms and staircases require cleaning more often.
