Help Determining Your Central Vacuum Hose
Hose Notes:
We recommend upgrading the basic hose to an electric hose with pig tail if your house has a lot of carpeted flooring, as this will allow for compatibility with electric power heads to ultimately provide better carpet cleaning.
We recommend upgrading to a low voltage hose if your house has a lot of hardwood floors, this will allow you to turn the vacuum on and off with the flip of a switch from the handle. This will save power, and make a better cleaning experience.
Electric Hoses:

Electric Hose with Direct Connect
When you hear the words "direct connect" it refers to a 2-pin plug that connects directly into the inlet for power. This power is then sent to the handle for electric power brush compatibility.

Electric hose with Pig Tail (corded)
Pig tail is essentially just another term for 'corded'. You plug the cord into a nearby outlet, and then your hose will have the same benefits as a 'direct connect' hose. This hose is compatible with 99% of central vacuums and is the absolute best option when upgrading your hose.

A closer look at the Electric Hose Handle
Notice the two-hole female end for electric application. If your current hose handle doesn't have any pin-holes like the one pictured, you will have a low voltage or basic hose.
See below for more details on low voltage and basic hoses.
Low Voltage Hoses:

Low Voltage hose with Button Lock
Button Lock is a mechanism for locking in your vacuum wand, or attachment, into the hose handle so it does not accidentally separate when vacuuming. The handle of low voltage hoses will have a useful on and off switch for your convenience.

Low Voltage hose with Friction Fit
Friction fit is your typical vacuum connection, the hose handle will just press into the attachment or wand with friction keeping it in place. There is a switch on the hose handle that allows you to turn the vacuum on or off with the press of a button.

Low Voltage Wall End
A look at the low voltage wall end. Notice the switch in the pictures above - If your hose handle has a switch, but the wall end doesn't have a pig tail or direct connect, it's a good chance that you have a low voltage hose.
Basic Hose:

Basic Hose Handle
This is a picture of the basic hose handle that we carry. This hose does not include a bleeder valve, nor does it have a button locking mechanism.

Basic Hose End
The end pictured has a metal ring that entirely wraps around the hose end. This results in the vacuum being in a 'always on' state when plugged into the wall.
If you would like the option of being able to turn the vacuum on/off by the hose handle, then we recommend a low voltage hose.
