1. Is your central vacuum system universal?
2. Is your hose and beater brush electric or non-electric? Take a look at your hose.
3. Now, based on what you have to work with, what would you like to do?
4. What Accessories fit?

Take a look below.

1. Upgrade to an electrical driven power brush (how to) (suggested for carpeted homes)
2. Buy 110 volt ELECTRIC central vacuum hose, power brush, complete kit, or inlet valve
3. Buy NON-ELECTRIC hose, power brush, complete attachment kit, or inlet valve
4. Buy Accessories or Supplies or Parts for all central vacuum systems and installations.

Upgrading to an electrical power brush and hose.

To upgrade your non-electric hose and power brush to electric:

1. Make sure you have an electrical outlet within 8-feet of each vacuum inlet where you will be using the electrical power brush.
   
2. Buy an 8-foot cord style or direct connect complete Electric Kit. See all of our Electric Kits.

1. NON-STANDARD: Wall inlet valve is NOT between 1 7/16 to 1 1/2 inches in diameter.

   Sears, Kenmore, Whirlpool, Budd, and Black & Decker typically had 1.25 inch diameter vacuum outlets. Unfortunately it is next to impossible to change out your inlet valves to the larger size inlets without ripping open the walls, but you can buy a new high quality crushproof replacement hose for your system. Complete line of products for Sears, Kenmore, Whirlpool and Budd and Black & Decker central vacuums.

2. Inlet valve hole is slightly larger than 1.5 inches. If the inlet valve hole is slightly larger than 1.5 inches, such as older Filtex models (that used a rubber end that go into an all metal inlet), you will need to use a hose with tapered cuff. If you want to replace the inlets you can have a much more functional system. Here is a turtorial of changing out inlet valves from an older Filtex valve with a pop out button. Also, here is a complete list for Filtex replacements.

1. The power unit on/off feature, on hoses with a handle switch, will not function with these valves. But you can use a corded hose to have control over a electric power brush. Or, you could use a non-electric hose, with no switches, and non-electric power brush.

1. Top emptying units (bag type filtration)
   1. Have MD, SilentMaster, FloMaster? View paper bag page.
   2. Have Nutone? View Nutone's one size bag.
   3. Have Filtex? There are 2 sizes of Filtex bags. View Filtex bags.
   4. Other brand? We might be able to direct you to the proper product if you email us.
2. Bottom emptying units (have no removable bag, but they always have a filter or screen which can or cannot be seen)
   1. Contact manufacturer for refer to the owner's manual for cleaning details.
   2. M.D.'s bottom emptying unit, AirMaster, does require an AirMaster foam filter (size is either 12 inch or 10.25 inch).

1. Inlet compatibility. Universal valves have an 1 1/2 inch diameter intake hole. If you have a question, send an inlet valve e-mail to MD.
2. Installing inlets in new or existing homes - see installation page. Make sure there is a small gasket joining the face plate and mounting plate. A gasket is built into newer mounting plates. If you are dealing with older valves or plates or if it is loose and leaks air, use some electricians tape around the face plate neck before inserting it into the mounting plate. Start with about 1.5 wraps tightly around the neck.
