A troop of robotic vacuum cleaners "waltz" with each other around a school gymnasium in this installation for the Biennale Interieur event in Kortrijk, Belgium. Interaction designer Pietro Leoni, of curator Joseph Grima's Geneva-based collective Space Caviar, programmed twelve Roomba vacuum cleaners to follow a routine created with choreographer Kostas Tsioukas. Leoni hacked the robots, removing their cleaning equipment and changing their wiring, to make the perform a specific set of movement instructions to The Blue Danube classical music piece by Austrian composer Johann Strauss. Six "male" and six "female" robots dance in couples to mimic a Viennese Waltz, with three pairs performing before three more.
