Note: If you do not have a suction cup tool for opening U-Scan, please follow the instructions using your hands, preferably with the gloves packaged with U-Scan or rubber gloves to aid in gripping the device.
Daily cleaning and upkeep
The U-Scan's surface is designed to be rinsed with each toilet flush, keeping it relatively clean every day. If necessary, you can clean the surface of the device with a mild soap and pat dry with a soft cloth or paper towel.
Warnings:
- If your toilet's design prevents the U-Scan from being rinsed with the water from the toilet's flush, it is recommended to rinse the surface of the device with a cup of water on a regular basis.
- Please only use mild soap and water to clean the surface of the U-Scan. Do not apply any other cleaning products, as they may affect the U-Scan's lifespan and accuracy.
- Do not use any toilet cleaner/deodorizer blocks in your toilet while U-Scan is installed, as it can lead to measurement contamination as well as discoloration of the U-Scan.
- Do not use toilet paper to dry off the U-Scan after cleaning. Toilet paper may clog the collection point of the device, leading to measurement failure.
- Please remove the U-Scan before cleaning your toilet. Bathroom and toilet bowl cleaning solutions often contain abrasive chemicals that can damage U-Scan.
Daily purging process
Every day between 11:00 am and 12:00 pm, U-Scan will automatically purge its fluid collection tube (used to collect your urine sample) by blowing air into the tube. This process is meant to remove any incidental fluid that is remaining inside the collection tube to ensure that the next measurement is as accurate as possible and to avoid any buildup of humidity within the device. You will hear mechanical whirring noises coming from the U-Scan while it purges.

Deep cleaning process
Deep cleaning of the device is highly recommended and will be suggested by the app when:
- a Cartridge is replaced
- the collection point of the U-Scan is potentially clogged, resulting in measurement failure
Deep cleaning is two-fold:
- External - The surface of the U-Scan is cleaned by being submerged in a mixture of detergent (packaged with the U-Scan) and water inside of the U-Scan Station.
- Internal - The fluid collection tube inside the U-Scan is cleaned by collecting a mixture of water and cleaning powder (packaged with the U-Scan’s Cartridges). Rinsing the U-Scan with water afterwards helps pump the remaining detergent in the fluid collection tube out of the device.
To deep clean your Withings U-Scan, follow these steps:
- Remove U-Scan from your toilet and dry it thoroughly with a paper towel.
- Open the Withings app.
- Go to Devices > U-Scan > Clean and charge U-Scan.
- Open the U-Scan:
- Position the suction cup on the center of the U-Scan's cover and hold the U-Scan in one hand and the suction cup handle in the other.
- Press down firmly on the suction cup to create a seal between the suction cup and cover.
- Twist the suction cup handle counterclockwise along with the cover to close the U-Scan. - Confirm that the gasket is in place and tap Yes.
- Close the U-Scan:
- Position the suction cup on the center of the U-Scan's cover and hold the U-Scan in one hand and the suction cup handle in the other.
- Press down firmly on the suction cup to create a seal between the suction cup and cover.
- Twist the suction cup handle clockwise along with the cover to close the U-Scan. - The app will ask you to confirm that you have lined up the arrow with the dot to ensure a watertight seal.
- Tap Confirmed.
- Fill the Station with water and cleaning powder (detergent) up to the gray marking.
- Tap Next on-screen.
- Unplug the cap from the USB-C port on the side of the Station, as your device will also charge during the cleaning process.
Note: Make sure the area around the USB-C port is dry so no water enters the port. - Plug the Station into a power source.
- Tap Next.
- Insert the U-Scan by:
- threading the toilet clip through the top of the Station cover, making sure that the arms of the cover cradle the top of the U-Scan's body
-
aligning the U-Scan's shell side with the shell icon on the Station.
- The Station's status light (LED) will turn white to indicate the U-Scan is detected.
- The U'Scan's status light will turn orange to indicate the U-Scan is charging. You should be able to see the orange light through the top of the Station.
- Tap I see an orange LED to confirm.
- The app will confirm that the deep cleaning has started and will take 3.5 hours to complete.
- Tap Next and then Exit.
- The U-Scan will start emitting motor noises within 20 minutes, indicating that the internal cleaning has commenced.
- After 3.5 hours have passed, you should receive a notification on your mobile device that the deep cleaning has concluded.
Tap on the notification to proceed. - Remove the U-Scan from the U-Scan Station and rinse it under room temperature water running at a medium flow for at least 20 seconds. You should hear the device as it pumps water through the fluid collection tube to clear out any remaining detergent.
- The U-Scan will eventually stop pumping and its status light will turn off, indicating the conclusion of the cleaning cycle.
- Dry the U-Scan with a kitchen or paper towel. Be careful not to use toilet paper, which may block the collection point.
- Follow the instructions to change your Cartridge if necessary. When closing the device, ensure that the gasket is in place and the device is completely sealed closed.
- Place the device back in the toilet.
- A scheduled purge will happen within 20 minutes, and the U-Scan won't be available for another measurement during this period.
Note: If you want to store your U-Scan for a period of time, you can do so after the scheduled purge is finished. Simply dry off the U-Scan as well as the Station and store both items in a dry place out of direct sunlight.
