Central vacuum cleaners combine powerful suction and unparalleled filtration to remove dust and other contaminants from your home. Unlike a traditional vacuum cleaner that recirculates air, central vacuums exhaust the air outside of your home. With the Hide-A-Hose patented central vacuum system there's no need to drag that central vacuum hose from outlet to outlet. Hide-A-Hose stores the vacuum hose inside walls and can be retrofitted into existing systems.
