I've been a bad Dobby Mummy!!

Having a black Dobby & living in the middle of agricultural land, I have been taking it through the jet wash every few days to remove the mud . . .
My partner decided to take his Qashqai through the normal auto carwash & all was good so I thought I'd do the same (as I miss lots by using the jet wash)
bad move . . the brushes seemed to have killed my rear wiper . . please help!

Has it broken the arm off or has it just stopped working?

It broke the arm, but managed to fix it, thanks for taking the time to answer
