Hello Alexandra
You can run the robot with water only or by adding a small amount of your own iRobot cleaning product. It is also compatible with BONA cleaning products.
Best regards,
Your iRobot team

It is recommended that only pure water be used. The information available does not mention the use of scouring products, and the lack of specifications on this subject suggests that you stick to the basic instructions provided by the manufacturer. For specific advice, consult the official user guide or contact iRobot support directly.
