Central Vacuum Cleaners, Information for Homeowners
With the increased size of residential homes, the idea of a central vacuum system is a new added feature some may consider. Just exactly what is a central vacuum and how does it work? Here is a crash course, in 500 words or less, about central vacuum systems.
In general, a central vacuum system is composed of 3 basic components, the main power unit, usually installed in a basement or lower level; the inlets, openings in the walls in each serviced room which connect to the main unit; and the hose and attachments.
The main unit draws the vacuum that is supplied through the room inlets throughout the house. When the hose and/or attachments are connected, the system is activated and vacuuming can begin. Some high-traffic locations, such as the kitchen or a breezeway, may warrant a vacpan. This in an inlet that has an activation switch. Once turned on, one can simply sweep dirt and debris up close to the inlet and it will be vacuumed into the vacpan opening.
In terms of the central vacuum unit, three types exist. The first, a fabric drop down filter, has reusable/cleanable filters. The filters are simply shaken out and re-used. Debris collects in the canister, which is then periodically emptied. The second type of unit uses a paper bag filter. Much like conventional vacuuming, dirt is trapped in a paper bag, which also filters exhausted air. These bags are disposable. The third variety of central unit uses cyclonic separation. No bag or filter is used. The cyclonic nature of the design allows much more air flow, using centrifugal force to separate debris. This system requires outside venting. For maximum particle reduction, outside venting is recommended for any system. Next for consideration are the inlets.
To determine the location and number of inlets throughout your home, follow this rough guideline. Approximately one inlet each 700ft2. Each individual manufacturer will work with you to see that you have the proper number installed. The next option with inlets is to install either standard or electrical inlets. Considerations include whether or not your home is a new or existing construction; variety of flooring types; and the presence of shedding pets. Here are the benefits and limitations of each of the two inlet types.
Standard Inlets do not have electrical power, so that certain attachments may not work with them. To provide power for an electrical attachment, you would need an attachment that could be plugged into a regular outlet. Standard outlets do provide the ability in the handle to turn the unit on and off. One can install standard inlets in both new and existing residences.
The electrical inlets are wired with 110 current, so that electrical attachments are powered automatically when plugging into the inlet. You can also turn on the power unit from the handle. You will need a licensed electrician for installation of the 110 line. Due to the need for running wiring, the electrical inlets are typically installed in newly constructed homes. It is not impossible to install in an existing home, but the wiring is a bit more complicated.
Attachments are as many and varied as for conventional vacuums. Hoses come in varying lengths and the correct one can be chosen with some advice from your central vacuum dealer.
Central vacuums may not be for everyone, but it never hurts to check one out and see what advantages it may hold for you.
