* Air quality: These systems are considered quite good for maintaining and impoving air quality because they can literally take the debris and dust out of the house. Plus, when the canisters are cleaned, the mess doesn't end up back inside the home. * Suction power: These vacuums are known for offering quite a bit more power than standard vacuums. Some estimates have them at three to five times as strong as regular vacuums. * Value: A central vacuum system can add to a home's value and even increase the sales appeal. This in and of itself is often seen as a huge perk. * Ease: These systems don't require the toting of a vacuum around to clean up a house. The hose and attachments might, but this sure beats lugging a heavy machine up and down stairs. When properly designed, these systems make it very easy to clean an entire house from top to bottom with minimal effort and lifting. * Sound: These machines are known to be a whole lot less loud than a typical vacuum. Since the suction unit is in a remote location, the noise produced while vacuuming is quite minimal. * Pricing: These systems can be a little expensive to have installed, but they can pay for themselves over the course of their lifetime.
