I think the main problem with Refbot in Series 4 was that he was simply designed to ensure that two locked together robots could be separated, and not because he was effective at it. Instead, it was simply because they did not want to confuse viewers with the House Robots freeing opponents instead of attacking them. They may as well have introduced Shove into the wars instead, he was seemingly much better at this job in Series 4
