I must run my V9 Pro with "Strong" suction. My Android app says that's what it's using, but in fact it always starts in "Normal." To get "strong," I have to set it to something else and then back to "strong." This keeps me from scheduling any automatic runs, as I have to be there to adjust suction. I don't belive this is the way it's supposed to work. What can I do? Yes, firmware is up to date.
