This is a good suggestion, it would definitely help to be able to distinguish which vacuum it is talking about. This is done for almost every other device, including cameras, sensors etc…they will all tell us the name of the device in the notification, so it makes sense this should be done for the vacuums too. Great idea!
This seems to also effect Alexa. I haven’t used the voice commands for a while, but iirc you have to say “Wyze robot vacuum”, not just the name of the vacuum.
