Possible commands for vacuum.send_command service for Mi Vacuum Roborock S50

I just got my Roborock S50 vacuum and start to play around with it in HA. I notice there is a service called vacuum.send_command but I am not sure what are the available commands I can use other than set_dnd_timer in the example. Please help.

Overall how is the experience (hardfware wise) and the integration in HASS?

Planning to buy one, trying to chose which model (currently at 320 Euro)

It’s good. Buy it. You won’t regret. Integration works well.
