I found that one of their old android application uses them, so I reverse engineered the app and found all that codes. These are actually serial commands send to the serial inside of the vacuum. 
I haven’t updated the firmware of the vacuum. I left it with the one that it came with. Works perfect with 970T model. After the latest HA update, the custom card I made is not sending commands. I’ll figure out what I have to change in order to fix the problem it has.
