How do I add 2 different robo vacs to the same app?

When I added the new device it deletes the older one

Hi,

1. After configuring the two devices, please swipe left and right on the device interface to check if you can see both devices.

2. Please ensure that you are using the same account to configure them and that the account is set to the same region.

If the issue remains unresolved and you are a user in North America, you can contact support.na@dreame.tech for support. Also, kindly provide a video of the problem and the two devices' SNs to help with diagnosis.
