So many moving parts that can break. I am already sad my robot vacuum cleaner broke (it's the moving lidar that broke). I have to send the entire thing including dock back to the manufacturer (very expensive).
My preference would be ifixit level guides where you can easily replace parts yourself. Then it would be perfect if the same servo is used everywhere so I can have 3 or 4 stored somewhere.
In general, a cost optimized robotic platform for a consumer market, has inverse specifications compared with reliable industrial robotics.
Industrial robotics like all machinery can be dangerous, and could still get your firm slapped with an export restriction. A lose-lose product class from a business perspective. =3
