These brush accessories effectively help the vacuum cleaner clean floors. EFFICIENT CLEANING - The Roomba roller brushes are perfectly matched: one lifts dirt while the other sweeps it away. Edge-sweeping brushes reach deep into corners and edges to remove dirt, dust, and debris. The high-efficiency filter captures 99.98% of dust, dirt, and particles as small as 0.3 microns. EASY TO USE - Clean by hand washing in warm water and allow to air dry completely before reuse. Regular cleaning helps maintain suction power and extends the life of your vacuum. For best results, replace edge-sweeping brushes and filters every 2 to 3 months. WHAT YOU GET - Includes 1 set of dual multi-surface rubber brushes, 3 filters, 3 edge-sweeping brushes, 1 cleaning brush, and 1 screwdriver. If the side brushes are bent, soak them in warm water for a short time to restore their shape.
