But on this threat model? Why would it not be good?
It has to physically accessed on the PCB itself from what I gather.
There are 2 “threats” from what I see:
-
someone at the distribution facility pops it open and has the know how to install malware on it (very very unlikely)
-
someone breaks into your home unnoticed and has the time to carefully take apart your vacuum and upload pre-prepared malware instead of just sticking an IP camera somewhere. If this actually happens, the owner has much much bigger problems and the vacuum is the least of their worries.
The homeowner is the other person that can access it and it is a big feature in that case.


It is funny because electric motors have nearly unlimited* torque depending on the kind. If you have thick enough power cables and winding conductors, you can just keep pushing it harder to get more torque.
It is like the thing they are very good at, besides sound levels, double or triple the efficiency, low/no maintenance, simpler with less parts, no emissions, etc…
Literally the only good thing about combustion engines are their fuel source energy density.
I think the problem is that motorheads see the enshittification of the auto industry as a whole and just say it’s because of electric motors because it happened right about the same time as EVs started coming out and try to push back on the wrong thing.
