Vacuum cleaner robots, on each of which a mini projector is attached, move within a darkened room. They project videos of 3D animated animals, walking in a loop, isolated, in front of a black screen. Depending on the position and angle, the machines produce aleatory image compositions. In contrast to the physical space constantly cleaned by the robots, the virtual space of the animated animals is an antiseptic space; Free from odors, dust and physical abrasion. Just like the robots, the animals are caught in the movement of progress, in form of a cyclic animation sequence. Their stagnating on the spot is mirrored by the programmed stretches of way of the vacuum cleaners, which carry the projections through the exhibition space. In a maximally controlled setting, the animals become pledges of a constructed „nature“. At the same time, the vacuum cleaners continuously measure and process their habitat.
