How to remove and install the roller mop?

Friendly reminder:
If you encounter situations such as the robot's roller mop not being installed or the roller mop becoming tangled during use, you can attempt the following steps:
I. Removing the roller mop
Double-click the AUTO button on the ROBOT. The roller holder will automatically extend outward.
2. Press the release button on the inner side of the roller holder with your finger, then gently pull the Roller End Cover outward; remove the roller mop.
3. Apply slight force to pull out the Roller End Cover; this separates the Roller End Cover from the roller mop.
Note: The roller and mop are integrated as a single unit; the mop cannot be replaced separately.
II: Installing the Roller Mop
Reattach the Roller End Cover to the roller mop.
2. Align the roller mop with the roller motor and gently push inward until you hear a "click" indicating proper installation. The Roller End Cover should be flush with the top of the roller mounting bracket.
3. Double-click the AUTO button on the ROBOT to automatically retract the roller mop.
Note: Both installation and removal must be performed in the extended position. Do not double-click the AUTO button while inside the station.
