What did bohr's model of the atom do that rutherford's model did not?

Rutherford came up with a model of an atom which he described consisted of a nucleus in the center surrounded by a cloud of electrons. Neils Bohr on the other hand improved upon this theory by stating that the atom does contain a nucleus in the center, but the electrons surrounding it do not exist as a cloud, rather, they exist in fixed orbitals (shells) around the nucleus, just like planets in our solar system. His argument was that if Rutherford's model were accurate, then the electrons would eventually have clashed into the nucleus and cause the collapse of the atom.
