I like central vacuum cleaners. Having the power head in the garage and a series of inlets throughout the house all connected by tubing hidden in the walls is the equivalent of having structured wiring for your telephone, data, and CATV needs. What I want to bring to your attention, whether you are planning a new install, adding a new inlet, or just replacing the hose, is that you need to make sure that the hose matches the inlet.
All inlets have two, spring-loaded metallic nubs that make contact with a ring on all hoses when the hose is inserted in to the inlet. This low-voltage contact triggers the power head motor to turn on when the hose is inserted and off when the hose is removed. The Nutone NU360 is a standard, low-voltage inlet.
In additon to the low-voltage contacts, there is another type of inlet that has a trapezoidal shaped connector above the circular inlet that allows 120 VAC, household electrical current to safely flow through the hose and drive power brushes and other AC-powered cleaning accessories attached to the hose. The NUCI390 is an example of an electrified, direct-connect inlet.
So which hose do you use? If you have the standard, low-voltage inlet, then the NUCH230 is the hose for you. If however, you needed more cleaning oomph in the form of an electric power brush, you would need to get a different hose such as the NUCH520. The ‘520, pictured above, can be inserted in a standard inlet, and comes with a six-foot, pigtail AC power cord attached to the inlet side of the hose. The pigtail allows connection to a nearby electrical outlet thus allowing the use of the power brush.
The third and final hose is the NUCH620. This is an electrified, direct-connect hose. No pigtail. Just plug it in and you’ve got both suction and AC power at your control.
