Methods, systems, and devices for debris permutation are described. A robotic device may identify a cleaning trigger for a first surface region (e.g., a cleaning schedule, a notification from a remote device). The robotic device may activate one or more rotors o based at least in part on the surface cleaning trigger and move to an aerial position proximal to (e.g., above, diagonal to) the first surface region using the one or more rotors. The device may displace debris from the first surface region to a second surface region using a pressurized air stream.
