Maintenance
Automatic Self-Cleaning Program
To maintain optimal performance and hygiene, activate the automatic self-cleaning program after each use. Press and hold the self-cleaning button for 3 seconds. The appliance will use high-temperature steam to clean the brush roller and internal pipes, flushing away residual grime. This minimizes manual cleaning and prevents odors.
