6.2 Cleaning Modes
The Vexilar T6T7T8 offers four cleaning modes:

- Edge Clean: Cleans along walls and furniture edges.
- Mop Mode: Engages the mopping function for hard floors.
6.3 2-in-1 Sweeping and Mopping
The robot can simultaneously vacuum and mop. To use the mopping function:
- Fill the water tank (200ml capacity) with clean water.
- Attach the mop cloth to the water tank.
- Insert the water tank assembly into the robot.
- Select Mop Mode via the app or remote control. The electronically controlled water pump allows for adjustable four-level water output.
