I'm using the Roborock app for Android ver 3.2.18 (most recent in the Play Store) with the S7 + auto clean dock. firmware ver 02.15.00 .
Since the UI major change where the robot operating modes are divided to tabs (Vac & Mop, Mop, Vacuum, Customize),
I noticed a major bug where if you start the robot on deep mop mode, it would stay on this mode without any indication of that in the app :
for example, I switched to deep mop and started the robot on Full clean, it had finished and returned to dock. A day afterwards, if I start the robot again on "full", there is NO INDICATION in the app that it would not start the vacuum, and it only starts cleaning in deep mop mode (no vacuum) -
to be perfectly clear, the operation mode icon does not change to indicate it's in mop only mode! it still shows vacuum/mop icon (the one with the divider line).
The only way to return the cleaning mode to Vac & Mop, is to manually switch to Mop (the robot beeps),
and switch back again Vac & Mop (robot beeps). ONLY then, the robot would start the vacuum (and mop) on the next full clean.
