The Refbot pullback was based upon the Series 4 version of its real life counterpart. Because of this, it does not feature the electronic countdown board and the electronic carding system, both introduced in Extreme 1. The two arms moved with the aid of a button on its back. Pressing the button made the pincer arm move upwards, the extinguisher arm move downwards and the head turn to the right. The pincer was fixed in position. It also featured a "Bump and Change Direction" style drive, like the Shunt pullback, meaning if it hit an object it would either change direction or reverse.
