1. A self-cleaning sensor system of a motor vehicle, the self-cleaning sensor system comprising: a plurality of object sensors, with each of the object sensors having a lens surface facing an associated one of a plurality of regions that are different from one another and located external to the motor vehicle, with each of the object sensors generating a signal associated with at least one of an image and a video of the associated regions; a plurality of lens treatment devices for applying an associated one of a plurality of remedies to the lens surface to remove an obscurity formed on the lens surface of the associated object sensor, where the remedies are different from one another and each of the remedies is configured to remove an associated classification of the obscurity from the lens surface, wherein the plurality of lens treatment devices include a heat-based lens treatment device for applying heat to the lens surface to remove the obscurity formed on the lens surface of the associated object sensor, a liquid-based lens treatment device for delivering a pressurized liquid to the lens surface to remove the obscurity formed on the lens surface of the associated object sensor, and a gas-based lens treatment device for delivering a compressed gas to the lens surface to remove the obscurity formed on the lens surface of the associated object sensor; a computer including at least one processor electrically communicating with each of the object sensors and the lens treatment devices, and the computer further including a non-transitory computer readable storage medium storing instructions, such that the at least one processor is programmed to utilize a multi-task neural network to: determine a classification of the obscurity in response to the at least one processor receiving the signal from the associated object sensor; generate an actuation signal based on the classification of the obscurity; and transmit the actuation signal to the associated lens treatment device; wherein the associated lens treatment device applies the associated remedy to the lens surface in response to the associated lens treatment device receiving the actuation signal from the at least one processor; wherein the at least one processor is further programmed to: determine that at least a portion of the obscurity is disposed on the lens surface after the lens treatment device applied the associated remedy to the lens surface; count a number of attempts taken to remove the obscurity; compare the number of attempts to a maximum threshold; and generate the actuation signal in response to the at least one processor determining that the number of attempts is below the maximum threshold; wherein the associated lens treatment device applies the associated remedy to the lens surface in response to the associated lens treatment device receiving the actuation signal from the at least one processor.
