If you receive the message "U-Scan Requires Cleaning" in the Withings App, this indicates that there is a clog in the device that is preventing your U-Scan from working properly. 

Typically, a deep cleaning will solve this issue; however, in some rare instances, further action is needed.

If the deep cleaning doesn't solve the issue, try the deep cleaning process with vinegar, as detailed below:

1. Prepare the Station for cleaning, following guidelines in our article.
2. Fill the Station with white vinegar so that the bottom 1/3 of the U-Scan is covered (enough to fully submerge the collection point) when placed inside.
3. Run the cleaning cycle as indicated in the app.

If you still receive the cleaning message, please reach out to our Support for further assistance.
