So I bought a bunch of tools the other week - Makita LTX battery series. Including with the kit came a poster with all the things you can buy that run off the same battery series. In addition to the fan vest and the heated vest, they also have their version of the roomba.
I settled for just the saws, drills, and sanders that I actually needed. Well, and the strimmer that my wife needed.
Medievalists and Medieval-adjacent. Sort-of.
