Product Help - S20 Pro

[S20 Pro Handle Installation] Adjust the direction of the handle's end and insert it into the port on the floor cleaner device following the arrow direction. Once you hear a "click" sound, ensure the handle is firmly in place without any looseness. This signifies successful installation of the handle.

[Adding Cleaning Solution] Press the button on the right side of the roller brush cover and lift up to remove the cover. Pour the cleaning solution into the storage compartment (please do not use non-official Yunmi cleaning solutions to avoid damage to the machine). Fill to the MAX line, which is full. A fully filled cleaning solution compartment can last approximately 40 days (or about 20 water tank refills).

The S20 Pro can lay flat at a 180° angle, effectively addressing hard-to-reach areas such as under sofas and tables. This feature allows for a larger turning radius, making it more convenient to clean low-lying areas.
With its body edge being just 1mm thick, it can complete household cleaning tasks in a single go. It reaches dirt and dust along walls, table corners, and narrow spaces seamlessly.

When cleaning low areas, the S20 Pro slightly reduces suction power in lie-down mode to prevent blowing dust and lint, which could impact the health of sensitive individuals and pets by being inhaled. The entire device can be maneuvered into low spaces and flexibly rotated, ensuring thorough cleaning while preventing the scattering of dust and lint.

After completing the cleaning task, place the floor cleaner back into the charging base:

[Activate Self-Cleaning + Drying]: Press the [Self-Cleaning] button on the front side of the handle to start the self-cleaning mode. Once self-cleaning is complete, the drying mode will activate automatically.
[Activate Self-Cleaning Only]: Press and hold the self-cleaning button for 2 seconds to activate only the self-cleaning mode.
[End Self-Cleaning and Drying]: If you need to end the self-cleaning or drying tasks, you can briefly press the power button or the self-cleaning button.

Kind Reminder: Please promptly clean the dirty water tank components after self-cleaning is complete.

In a dry environment, static electricity is easily generated, similar to the sparks that occur when removing a sweater or the static shock received when shaking hands. In sunction mode, the high-speed airflow and the dry rotating roller brush may create static electricity through friction with the structural components. When your body comes into contact with it, a discharge may occur. This is a normal phenomenon and poses no harm. To avoid this, you can start in another mode for about 10 seconds before switching to suction mode; this can help prevent static shocks.

Press both the Mode button and the Self-Cleaning button when the vacuum is locked to switch the language.
