I mean, the speaker part makes sense. The vacuum has a speaker so it can make an alert sound of something’s wrong. The most common ones I hear are “please charge Roomba” and “error, please move Roomba” (that’ll happen if it rolls over a grate or something and the wheel gets stuck).
A speaker too. So you can mess with your pets while away or spy on your spouse. What an amazing product idea /s

But a cheap speaker is a pretty sensible feature.
At minimum, it might also have it for the “turning on” noise.
It might also just be the default beeper for the motherboard, and it’s just been reconfigured to make a particular noise instead of the usual beep.
