Rotary Roller with Falcon 40 watt Pro.

The bundle package was a Falcon 40 Watt Pro with the extended legs and the rotary roller. I have not found any info/videos using this rotary roller with the Pro model. Anyone using this with the pro model? Supposed to be delivered tomorrow. Anyone with any info would be greatly appreciated.
Just had a total knee replacement and wont be able to assemble and try for a couple weeks. Would like to know if I need to return this model for another to work with the rotary roller instead of waiting a few weeks to find out that’s what I need to do.
Thanks…
