Accumulated debris and environmental residues obstruct signal transmission and reception. Maintaining clear optical or radar paths ensures reliable autonomous vehicle perception and safety.

Suboptimal coordination between fluid delivery and wiper movement leads to streaking or incomplete debris removal. Precise sequencing ensures maximum visual clarity with minimal fluid consumption.

Accumulation of biological contaminants and pathogens on interior and exterior vehicle surfaces. Mitigating these risks ensures occupant safety and maintains operational hygiene standards.
