This works fine and came from a vacuum that worked fine. (The vacuum motor unit got cracked in the plastic. Machine did not mechanical issues). 
This listing is for the motorized carpet cleaning attachment with brush. It works great but has some scuffs as seen in pictures. It isn't perfectly clean but is pretty clean. Didn't feel up to doing a thorough brush cleaning but nothing gross happening here.
I tested this again yesterday to insure it is still fully functional as it hasn't been used in a year or so.
This is from a Riccar Pristine Stine 1 unit in the light green color. It may or may not fit later models.
This is a no-refunds listing so please do your homework to ensure it fits your machine.
I will be parting out other pieces on this vacuum. I have hoses, attachments, filters, etc. available. 
Feel free to contact me with inquiries on other parts.This is for the motorized head only. No other parts, hoses or attachments are included.
