Looking for a air tool rotary brush attachement

When I used to work at Delta Sonic we had an air tool (probably a grinder or sander) that had a brush attached to it. It was super useful for cleaning carpets and seats (both cloth and leather). Does anyone know where I could find such an attachement for an air sander or grinder (that would fit the cheap kind from Harbor freight)? I have been looking and have not been able to find anything.

The bristles were made of a stiffer plastic

Thanks!

 

If you can put a backing plate on the grinder with the velcro face then you could get get the PC leather/uhlpolstery/carpet brushes that have the velcro packing. I have 2 (medium & stiff) of them that fit a 5" backing plate. They are hard to remove from the backing plate because they do not flex at all. I stick a butter knife in between to break the velcro bond. They were cheaper than buying the PC brushes that are built with the BP and thread as single unit.

 

Thank you for your help! Using your info I found two types of brushes for the porter cable.

5" velcro you had recommended

and

this smaller non velcro brush

I think that for my use the smaller kind would be ideal since I could get into more nooks and crannies, and because it would not bog down as much.

I don't know anything about PC fitment, but do you think the small non Velcro brushes would fit into an air grinder/sander (I have not bought it yet, so I don't know what fits into it)? Could I make it fit into a flex?
