Using a vacuum is one of the best ways to create a healthy home. By vacuuming just once a week (or twice if you have pets) you can keep dirt, dust and other debris under control. But one more trick? Vacuum slowly. By going slow and moving the vacuum with overlapping strokes, you actually speed up the cleaning process by 85 percent. More dust, allergens, pollen, dirt and other debris get picked up with the slower motion of the vacuum.
