Need power brush for central vac system...

[Aimros]

I need to get a power brush so I can start cleaning the rugs in my home better. Do any of you with central vac systems have any good recommendations? I have pets so something that cleans up pet hair well would be great. I have a Zenex system but can't seem to find Zenex accessories for sale online. I don't know much about the system since we bought the house with it already installed. Thanks!
