Made from microfiber, the Roborock Mop Cloth removes ultra-fine dust that would otherwise be left behind by regular vacuuming. | Mount the cloth onto the water tank easily and quickly through the specially designed attachment slot. | The highly absorbent cloth soaks up water and distributes it evenly across its surface, giving you an even clean that lasts for up to 60 minutes. | High-quality Velcro locks the mop tight and flat and is tested to maintain as much as 80% of its effectiveness after 500 uses. | The cleaning area matches the width of the main brush, giving a perfectly matched clean that leaves all surfaces vacuumed and mopped.
