An automatic cleaning system is configured by a single controlling apparatus, and a plurality of self-traveling cleaners. When the controlling apparatus has received from a self-traveling cleaner a dust location signal containing a dust location detected by the self-traveling cleaner, it writes the received information into a storage unit. When the controlling apparatus has received from one of the plurality of self-traveling cleaners, with respect to dust which is not removed by any self-traveling cleaner, a signal requesting a reservation of removing the dust, the controlling apparatus will not accept from any other of the plurality of self-traveling cleaners a signal requesting a reservation of removing the dust, until receiving from the one self-traveling cleaner information indicating that removing of the dust has been completed or information indicating that the removing of the dust has been stopped.
