I saw this briefly on a YouTube video - 'wings' that slide out on the handle of the Dolphin M5 and maybe others. I didn't know about this, so I checked my Rosie, and sure 'nuff hers slide out too. I checked the manual and online - didn't have any luck finding out what they do. I bet Patrick knows!!! I pulled them out and put Rosie in the pool, but I didn't stay to see her in action with her wings open.
Here's a picture of Rosie with her wings.....
