The actor signed up for the part in May last year and was introduced on screen two months later. His current storyline sees Rob trying to steal away Underworld's clients after his sister Carla Connor (Alison King) sacked him from the factory.
Speaking on Daybreak this morning (January 9), Baylis praised Rob's development over the past few weeks.

Baylis commented: "He's really starting to come into his own. I'd rather it be that way as a process on the job myself - the slower that it unravels for me, the more interesting it gets to play.
"It feels that over the Christmas and New Year period, there's been a bit more interest in what's going on with the storyline, which is great."
Baylis also spoke further about Rob's upcoming romance with schemer Tracy Barlow (Kate Ford), hinting that it begins when she lands a job at the factory.
He said: "Kate's been an absolute dream to work with. It is slowly bubbling under the surface. I'm not going to give too much away, but it definitely rubs people up the wrong way that this is all going on. Especially because it all starts in the factory as well."
Meanwhile, asked how he is coping with recognition from Coronation Street fans, Baylis replied: "That is something that you just have to get on with. There are ways that you can cope with that.
"I'm not actively going out looking to be recognised. Life's too short - that's not the life that I want to live, to be honest. There's ways and means around it, and when it does happen, it's generally on a positive note anyway."
