Vacuuming the house depends on the people and pets living around the house. Typically, a house should be vacuumed twice a week, especially for those who have allergies, and for pet owners. This helps in keeping the house clean throughout the entire time. However, there is no amount of times that a house should be vacuumed. Generally, vacuuming a house should be done anytime that dirt starts to build up in the house. Those who are living in dusty regions might be forced to vacuum their houses more often as compared to those people who live in dust-free areas.
