INTERNAL CLEANING FOR AUTONOMOUS VEHICLES

Aspects of the disclosure relate cleaning systems for cleaning cabin air and interior surfaces of a vehicle. For instance, a cleaning system may include a surface cleaning device including a UVC light source. In addition, a request for confirmation that the vehicle may not be occupied may be sent to a remote computing device. In response to the request, a signal indicating whether or not the vehicle is occupied may be received. The surface cleaning device may then be activated based on the signal.
