## Summary description

Bosch Aerotwin Flatblade A890S is a flatblade windshield wiper set with lengths 650 mm and 500 mm. The set features a frameless aerodynamic design for consistent contact with the windshield, reduced noise and even wiping. Intended for vehicle front windscreen use, it replaces conventional beam or bracket-style wipers and suits wet-weather visibility improvement.

## Long description

Bosch Aerotwin Flatblade A890S 650 mm + 500 mm is a frameless windshield wiper set designed for front windscreen use. The set contains two flatblade wipers in lengths 650 mm and 500 mm, engineered to maintain consistent contact with the glass surface. The aerodynamic, beam-style construction reduces lift at higher speeds and minimises noise while delivering even wiping across the sweep area. This replacement set is intended to improve wet-weather visibility and is compatible with vehicles that use beam or bracket-style front wipers of the corresponding lengths.
Advantages
The frameless Aerotwin profile provides uniform pressure distribution along the blade, which ensures streak-free wiping and extended rubber contact. Its aerodynamic shape reduces wind lift and decreases operational noise at highway speeds. The flat design resists ice and debris build-up and simplifies installation compared with some multi-component bracket wipers. Constructed with quality materials, the blades offer consistent performance in rain and light snow conditions.
Suitable for
Replacement of front windshield wipers in passenger cars that require 650 mm and 500 mm blade lengths
Improving visibility in rainy and wet driving conditions
Drivers seeking a low-noise, aerodynamic flatblade alternative to conventional bracket-style wipers
Key specifications
Blade type: frameless flatblade (aerodynamic beam)
Lengths: 650 mm (driver side) and 500 mm (passenger side)
Application: front windshield
Design features: uniform pressure distribution, reduced wind lift, low-noise operation
Environment: suitable for rain and light snow conditions
How to use
Refer to the vehicle owner manual for the correct blade length positions, then remove the old wipers and fit the Aerotwin blades using the manufacturer-specified adapter or attachment method. Ensure the wiper arms are in the parked position before detaching the old blades. Align the replacement blade with the wiper arm connector and secure until it clicks or locks in place. After installation, test the wipers on the windshield at low speed to confirm correct fit and even contact across the sweep.
Usage recommendations
Regularly inspect the rubber edge for wear or damage and replace blades when streaking, chattering, or reduced wiping performance is observed. Clean the windshield and blade rubber periodically to prolong service life. For winter conditions, consider lifting the arms when parked to prevent freezing to the glass and avoid using wipers to clear heavy ice or snow.
