Clean the floor, approach nothing else
A charging bay contains equipment that is energised, connected and in some cases holds material a cleaner has no basis for handling. The instruction has to be unambiguous: nothing mounted, plugged in, connected or belonging to the charging equipment is cleaned, wiped, moved or touched. That includes cables on the floor, which are left in place and worked around rather than repositioned. Nothing is unplugged, coiled, hung or tidied for any reason.
The floor itself is a normal warehouse surface and can be cleaned normally, with one adjustment: methods are chosen to keep water away from equipment. That usually means dry removal in the immediate vicinity and any wet work kept clear of the bay, or done when the site advises it is appropriate. The scope should say which applies rather than leaving it to a crew.
