The carpet needs to be steam cleaned again .you most likely have gotten the end of the roll,which has more of the loose fiber in it,so much loose fiber can cause medical problems.so this is what you do, move everything off of the carpet , have it steam cleaned , tell the tec that cleans it why you are having it cleaned,, let it dry completely(stay off of it as much as possible while drying) then put a new bag in your vacuum and vacuum it completely. check your bag when done . a 20 x20 room should produce about a half of a bag of fiber on a NEW carpet. i see that your posting is 490 days old you ,you shouldn't have much fiber at all at this point i thought that i would reply to this post anyway just in case you're still having a problem.
