Be it snow or rain, mud or even debris, the windshield of a Mercedes Benz needs to be clear so that the driver have the full visibility in avoiding the bumps, potholes, or even accidents waiting to happen. It needs a device to wipe these eyesores not only to clean but to protect form harm, as well.
The windscreen wiper does this job. It cleans out unnecessary elements that pose as distractions to the focused driving vision of a Merc owner. The assembly consists of: the arm pivoting at one end, the motor that powers the assembly and the blade that attaches to the arm. The blade is swung back and forth over the glass, pushing water and other elements from its surface. Generally, the speed is being controlled with several continuous speeds and often one or more "intermittent" settings. Most automobiles use two synchronized radial type arms, while many commercial vehicles use one or more pantograph arms. To note, Mercedes-Benz pioneered a system called the "Monoblade" wherein a single wiper extends outward to get closer to the top corners, and pulls in at the ends and middle of the stroke, sweeping out a somewhat 'W'-shaped path.
