The self-styled cleaning fairy plead not guilty in an Ohio courtroom Thursday.
Susan Warren is now being held on a $5000 bond.
Westlake, Ohio Police say Warren broke into homes that didn't request maid services, but then left a bill for $75 written on a napkin.
Residents returned home and found it sparkling clean, and nothing was taken.
Still, it's a crime.
Warren claims she does it all the time, which could tie her to similar crimes in surrounding communities.
