You show me an Android-enabled washing machine, I will show  you a washing machine on HarmonyOS Eco-system. 

Why is HarmonyOS is "distinctly different" from Android.

I dunno enough of washing machines to tell you if they are using Android, but you shouldn't just cite one application.

Most appliances nowadays do not have an OS in them, as it's deemed to be an overkill. Instead they use low-cost microcontroller chips.

You put OS only when you need to include other higher functions that require sophisticated scheduling of resources etc.

I am certain Android is being used in many other devices besides your handphone. Examples are ATM machines, cars etc.
