The present application discloses a system for dispatching cleaning robots. The system includes an input subsystem configured to provide an input signal including information about foot traffic in a time period in an area. The system includes a processing subsystem to receive and process the input signal and further to determine a cleaning task under an operation scheme and generate a control signal for the cleaning task. Further the system includes a communication subsystem configured to receive the control signal from the processing subsystem and one or more first signals respectively from the one or more cleaning robots. The communication subsystem sends the control signal based on the one or more first signals to dispatch at least one cleaning robot to the area to perform the cleaning task and receives one second signal from the cleaning robot to update the operation scheme.
