Are you looking to upgrade your central vacuum system. If you have questions about what you should purchase, this guide might help you determine exactly what you need.
Do your valves have a plug on them?
If it has a plug you’ll need the direct connect. If there is no plug, you will need the Pig Tail hose end to use the electric brush.
Is there a plug located beneath the handle nozzle?
If there is a plug, is it flush or recessed?
This decides if the handle works with your wand.
