“Buffy” was one of the thousands of small, flying CLE-004 window cleaning droids on Coruscant. It worked together with an INS-444 window installation droid nicknamed “Mick,” taking instructions from a central computer. Together, the two droids replaced the bedroom window of Senator Amidala’s Coruscant apartment after the original window was destroyed through the actions of ASN-121 and Obi-Wan Kenobi.
