  We pioneer a new future in robotic dust collection by introducing passive
dust-collecting robots that, unlike their predecessors, do not require
locomotion to collect dust. While previous research has exclusively focused on
active dust-collecting robots, we show that these robots fail with respect to
practical and theoretical aspects, as well as human factors. By contrast,
passive robots, through their unconstrained versatility, shine brilliantly in
all three metrics. We present a mathematical formalism of both paradigms
followed by a user study and field study.
