Once a week: Your carpet is a place where dust, dirt and allergens tend to hide. Giving your floors a weekly clean with a good-quality vacuum cleaner is super important. In places with constant foot traffic, you may want to vacuum more than once a week.
Pro tip: If you need to spot clean a stain, you can mix a teaspoon of liquid dish detergent with a quart of warm water and ¼ teaspoon of white vinegar. Apply this mixture on the spot and then rinse and blot dry!
