Vacuums are a vital part of any house's cleaning equipment. Vacuum cleaners use suction to remove dirt and other particles from floors, upholstery draperies - even patio furniture. They're generally electric-driven. Central vacuums are considered semi-permanent appliances with a central extractor unit, usually placed in the garage or utility room, and hoses that run throughout the walls in your home. Access to an inlet port in each room makes it convenient to remove dust, particles, and small debris using the proper central vacuum attachments.
