Act as a robotics engineer with 10+ years of experience in designing autonomous cleaning devices. Create a high-quality, futuristic concept for an automated window cleaner robot that can operate on [glass skyscrapers], [residential homes], and [solar panels]. The design should include [self-charging solar panels], [AI-powered pathfinding], and [ultra-absorbent microfiber brushes] for streak-free cleaning. Emphasize sleek, compact aesthetics with [modular attachments] for different surfaces. The robot should be depicted in action on a [rainy day] or [dusty environment] to showcase its adaptability. Use a [blue and white color scheme] to convey cleanliness and technology. Include subtle branding elements like [a minimalist logo] on the robot’s body. Render the scene with realistic lighting and reflections to highlight the robot’s efficiency.
