On average, the carpet should be cleaned once every two months. However, this guide assumes that you have a vacuum cleaner with a rotating brush available that can pick up all the allergens in the air and assimilate them into its fibers. You may need to go through the process more frequently if you have a new puppy in the house or kids who tend to spill food on the floor. You should also clean your carpets more often, in case you notice any visible signs of soiling. For example, even a small stain on your carpet will get people’s attention right away. You must clean up as soon as possible after it takes place so that it doesn’t seep deeper into the fibers and cause long-term damage.
