ON-BOARD INFORMATION DISPLAY

A method of operating a cleaning machine can include determining if a human is detected nearby. If a human is not detected, the process can restart. If a human is detected, then a determination can be made if there is emergency information to show. If there is emergency information to be shown, then the emergency information can be shown. If there is no emergency information to be shown, then an attention seeking mode can be enabled. The presence of a target group can be determined. The availability of content relevant to the target group can be determined. If content relevant to the target group is available, then the content can be displayed. If content relevant to the target group is not available, then the method can restart or return to a previous step.
