The Bosch Aerotwin Upgrade eAR813S set of wipers includes blades of 650 / 450 mm and boasts a frameless construction.
Frameless wiper blade unleashes a streamlined flat spine, precision-engineered to maintain even line pressure across today’s sculpted windshields. A resilient metal spine pairs with a premium silicone edge, ensuring a crystal-clear pass. Its low-drag aero spoiler cuts lift at highway speed, while tool-free quick-click mount suits 95% of vehicles for rapid installation. The frameless build shrugs off snow and ice, eliminates corrosion points, and hugs modern glass shapes for superior visibility. Drawbacks: higher upfront cost, refill inserts are non-serviceable, plastic adapters may embrittle in severe cold, and clamping force declines slightly on very flat windshields. Rinse with pH-neutral soap every three months and replace every 12–24 months (6–12 months in extreme climates). Experience silent clarity – upgrade now.
