iRobot 4640236 Roomba 800 and 900 Series Replenishment Kit (Open Box) PRODUCT DESCRIPTION Everything you need to perform regular maintenance on your Roomba 800 or 900 Series Robot. Kit includes three Aero Force High-Efficiency Filters, two side brushes and one set of replacement Aero Force Extractors. Features: * Everything you need to help maintain your Roomba 800 or 900 Series Robot's cleaning performance in one convenient kit. * 3 AeroForce High-Efficiency Filters: The filter attaches to the dustbin to catch particles. A dirty filter weakens your robot?s suction power. * 2 Edge-Sweeping Brushes: Specially designed at an angle to sweep debris from edges and corners and into the cleaning path to be suctioned off your floors. Worn brushes don?t grab debris as effectively. * 1 set of replacement AeroForce Extractors: The AeroForce Extractors stay in contact with carpets and hard floors ensuring consistent suction of dirt and debris. A worn brush doesn?t clean effectively. * Compatible with Roomba 800 or 900 Series Robots. * It's important to replace your robot accessories with iRobot genuine parts. Genuine parts are designed and manufactured to the exact specifications set by iRobot. This ensures that each part not only fits perfectly but also operates in harmony with the rest of the robot, maintaining the designed performance standards. Non-genuine parts may choose to cut corners when it comes to material selection, method of fabrication, and quality control. Condition: Open Box Color: White Copyright All rights reserved.
