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 improves indoor air quality. HIGHLY EFFICIENT FILTERING TECHNOLOGY - Features two brushes that work together: one for loosening dirt and the other for sweeping it away. The side brush reaches deep into corners and edges to remove dust and debris. The filter captures 99.97% of particles, including dust, pet dander, and allergens as small as 0.3 microns. If the side brushes become bent during shipping, restore them by soaking in hot water for a short time. EASY TO CLEAN AND REPLACE - Clean components by hand washing in warm water and allow them to air dry completely before reuse. Regular cleaning and replacement of parts help maintain suction power and overall 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.
