Start cleaning from the app or the robot; the base station will automatically handle debris removal, nozzle washing and drying after sessions if configured.

Usage recommendations

For best results, clear loose obstacles from floors before running the robot, follow the manufacturer instructions for detergent dilution, and perform periodic checks of the dust bag and water tank. Use virtual walls or app-restricted zones to protect delicate items and to prevent access to areas with many small objects.
