Found a solution. You must have Samsung app called SMART HOME connected to the robot. Enable in the Alexa app and then device discovery in Alexa app. If you have the newer app Samsung SMART THINGS that fine but it does not work with Alexa as the app see it as a switch. SMART HOME see it as other. I use the SMART THINGS because it works well with my washer, dryer and schedules when the robot vacuum to come on. If you have both of those apps enabled in your Alexa app, you need to delete the duplicate robot device. The one that you need to delete is the robot that works through THE SMART THINGS on the Alexa device screen. Once you have the robot listed once on Alexa device page tied to SMART HOME you are golden.
