New, high-quality materials, well-made, durable, and highly compatible with the equipment. Clean accessories help maintain your home robot's optimal performance. Accessory components are easy to remove and replace as part of routine maintenance, helping to reduce the infiltration of dust, pollen, and other allergens into the air. For best cleaning and filtration results, replace the accessories every 23 months depending on usage frequency. The filter captures dust, dirt, and other impurities by the sweeping robot, keeping the unit clean and functioning properly.
