PREMIUM QUALITY MATERIAL - Made of high-strength and environmentally friendly materials to ensure optimal performance and a healthier lifestyle. This product helps maintain a clean home and supports improved indoor air quality. HIGHLY EFFICIENT FILTERING TECHNOLOGY - Features two brushes designed to work together: one removes dirt and debris, while the other sweeps. The side brush reaches into corners and edges for thorough cleaning. The filter captures 99.97% of particles as small as 0.3 microns, including dust, pet dander, and allergens. If side brushes become bent during shipping, restore them by soaking in warm water for a short time. EASY TO CLEAN AND REPLACE - Wash brushes by hand in warm water and allow them to air dry completely before reuse. Regular cleaning and replacement of parts helps maintain suction power and vacuum performance, extending the life of your robot vacuum. For best results, replace edge-sweeping brushes and filters every 2 to 3 months. Replace multi-surface brushes every 6 months.
