I want to change the language it speaks to English. It gives out some messages when it randomly stops while cleaning and I need to change the language to know what’s wrong.
From page 14 of the user manual: Take the Roomba off its base and press Clean. The lights should turn on.Press and hold Dock until the Roomba beeps and says the current language (about 3 seconds).Press Clean until you hear the language you want.Press and hold Clean to turn off the Roomba and confirm your language choice. I have attached the full user manual for your vacuum below. IRobot Roomba 800 Manual
