Is your Roomba Combo Essential (models like Y0140, Y0110, Q0520, Q0120, 105, etc.) starting to leave behind dirt or not mop as well? Time for a maintenance refresh! This 16-piece kit has all the consumable parts you need to get it running like new again. You get 1 main roller brush, 4 side brushes (those little spinning ones that get corners), 4 HEPA filters (crucial for trapping dust and allergens), and 6 reusable microfiber mop cloths. Regularly swapping out these parts is key to keeping your robot's suction strong, its navigation smooth, and your floors genuinely clean. The parts are high-quality and designed to fit perfectly, just like the originals. The mop cloths are absorbent and gentle on floors. It's a fantastic value bundle that saves you money compared to buying each part separately from iRobot. Pro tip: if the side brushes arrive bent from shipping, just soak them in hot water for a bit and let them air dry to bounce back to shape. Keep your little robot helper happy and efficient!
