The Xiaomi Mi Robot Vacuum-Mop Essential Filter is a replacement component designed to keep your robot vacuum operating efficiently. This white HEPA filter measures 156 x 50 x 27 mm and weighs just 40 g, ensuring it fits seamlessly into the device without affecting its movement. By utilizing high-quality materials, it captures up to 99.97% of fine dust, bacteria, allergens, and pollen from the aspirated air. This prevents these particles from being redistributed back into your living space, making it a practical choice for those who want to maintain a cleaner indoor environment.
