The cleaning agents should not be added to the Xiaomi Robot Vacuum X20+. The robot vacuum is designed to work with water alone in its water tank for mopping purposes. Adding any kind of cleaning agent, detergent, or chemical can damage the internal components, especially the water tank and the mopping cloth. Additionally, it can leave residues that could potentially harm the flooring or create a buildup inside the robot vacuum.
The mop rotates at 180 RPM, effectively removing coffee stains, dirt, water, and other spills from floors. For heavily soiled areas, activating deep cleaning mode enhances stain removal. If the mop cloth becomes too dirty, increasing the self-cleaning frequency of the robot vacuum can help keep it clean and effective.
If you want to use cleaning agents, it is best to apply them directly to the floor or surface before mopping, rather than adding them into the water tank.
