They did use robots leftover from the Lunokhod lunar exploration program and a robot sent by West Germany, however the radiation level was so high that they failed almost immediately. They had to resort to using "biorobots", as they cynically called the soldiers used to clean up the site. I'm not sure if modern robots would fare any better due to their higher complexity and use of lots of electronics which is sensitive to radiation.
