A:Answer For the Robot Vacuum E25 All-in-One Robot Vacuum and Mop Combo, there is no need to change or remove the roller between vacuuming and mopping. However, you will need to handle the installation and removal of the mopping module depending on whether you want to vacuum only or vacuum and mop simultaneously.
The mopping module is a black plastic plate located behind the rolling brush, and the mopping cloth is affixed to the bottom of this module. If you wish to vacuum only, you can remove the entire mopping module by pressing and holding it on the left and right sides to detach it.
When mopping, you need to fill the water tank, attach the mopping module and cloth, and start the operation. Ensure detailed instructions are followed for proper installation and operations. Please also note that with the mopping module installed, the auto-empty function will not work, and accessing the rolling brush and dust collector for cleaning might be challenging.
