The CLE-004 window cleaning droid, also known simply as a cleaner droid, was a fifth-degree window cleaning droid produced by Publictechnic during the time of the Galactic Republic. It commonly worked alongside INS-444 window installation droids. One particular CLE-004 unit, nicknamed "Buffy", along with the INS-444 unit "Mick", was employed by the staff of Senator Padmé Amidala in 22 BBY. The droids installed and cleaned a window in her apartment to replace one smashed by Obi-Wan Kenobi during his pursuit of an ASN-121 assassin droid.
