Roomba battery failure 

That is to change the language on the robot. My language is English

@@vincenguyen1 Unfortunately the happy sound is only compatible for older Roomba 500 series robots.

Baud rate change?

yes it's restart the robot software lol

Correct

Yep!

The vacuum being switched doesn’t sound right

@@ericxxonvf When you switch the vacuum bins the sounds are always different on the roombas

Because the 531 is picking up less dirt.

@@vincenguyen1 dfg scx

Because I wanted to.

@@vincenguyen1 I should’ve made a 670 look like a 530

@@vincenguyen1 I’m surprised older bins are compatible with the newer roombas

@@jimsdog23 the black one was 692 and the brown robot was 531

@@vincenguyen1 I kinda expected some of the 670 models to have the older version of the IRobot logo and the newer Roomba font. But if it doesn’t exist, then just buy a for parts Roomba older 600 series!
