Regular vacuuming –about once per week –will increase your carpet’s durability. Vacuuming removes particles that settle loosely on the surface of your carpet before they settle deeper and start abrading the carpet fibers. Regular vacuuming can allow you to go longer before needing professional cleaning.
However, no matter how often you vacuum, you will still need professional deep carpet cleaning sooner or later. So, if it’s been long since you hired a professional to clean your carpet, now is probably the best time to do so.
