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 removes dirt while the other sweeps debris. The side brush reaches into corners and edges to capture more dust and particles. The cleaning filter captures 99.97% of dust, pet dander, and particles 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 by hand washing in warm water and allow to air dry completely before reuse. Regular cleaning and replacement of parts helps maintain suction power and extends 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.
