A system comprises a processor and a memory. The memory stores instructions executable by the processor to determine a baseline polarization for a surface of a material based on a first polarimetric image of the surface, to determine a second polarization for the surface based on a second polarimetric image of the surface, to determine, based on the baseline polarization data and the second polarization data, that there is a wet area on the surface, and upon determining the wet area, actuate an actuator to cause a clean the surface.

A vehicle has a steering device with a manually actuatable steering input unit for manual gripping and inputting steering commands. The steering input unit has a one-piece or multi-piece gripping surface that is manually grippable for inputting steering commands, and a cleaning device for cleaning the gripping surface. The steering input unit is movable between a usage position, in which it can be gripped by the driver, and a non-usage position in which it cannot be gripped by the driver. The cleaning device has at least one cleaning box arranged on the vehicle and having or containing a cleaning device for cleaning the gripping surface. In the usage position the steering input unit is arranged outside the cleaning box at least in the region of the gripping surface and in the non-usage position it is arranged inside the cleaning box at least in the region of the gripping surface.

Systems and methods are directed to automated cleaning systems for vehicles. In one example, a vehicle is provided that includes a drive system, a passenger cabin, and a vehicle cleaning system. The vehicle cleaning system includes a vacuum unit and a robotic manipulator. The robotic manipulator includes an arm including a plurality of arm sections and a gripper unit positioned at a distal end of the arm. The robotic manipulator is connected to the vacuum unit such that the arm provides a vacuum path between the vacuum unit and the gripper unit.

According to one aspect, a vehicle includes a first compartment, a system, and a first sanitizing arrangement. The first compartment has a plurality of walls that define a space, and the system is configured to enable the vehicle to travel autonomously. The system includes a power system configured to provide power to the first compartment. The first sanitizing arrangement includes at least a first sanitizing component, the at least first sanitizing component being included in the first compartment, wherein the first sanitizing arrangement is configured to be activated to sanitize the plurality of walls and the space.

Vacuum cleaners to be mounted in a vehicle are disclosed. Some of the vacuum cleaners have a modular design that allows the vacuum cleaners to be arranged, assembled, and/or installed in different configurations and to fit in different spaces within the vehicle. Vacuum cleaners may include a vacuum module, a collector module, and/or a hose storage module. An interconnecting duct is configured to operatively couple the vacuum module and the collector module in any one of a plurality of different predefined assembly configurations. The collector module may have a debris canister that may be lifted straight out of a collector housing. The vacuum cleaner may be installed in a vehicle in a manner to allow easy removal of the debris canister without disconnecting and/or removing other portions of the vacuum cleaner.
