You can if you have the parts (and the skills). I've just recently learned that technically you don't even need the PCB and can use a USB UART directly on the vacuum's pins.
However, I don't plan to become part of a community where the only place to discuss issues is a centralized walled garden which I got banned from and I can't recommend anyone else does either.
Do you have a link to any docs showing this? I've been looking at supported vacs but want to avoid the pcbs if at all possible.

Not sure how I missed that. Thanks!
