Let X be a metrizable space and Comp (X) be the hyperspace consisting of non-empty compact subsets of X endowed with the Vietoris topology. In this paper, we give a necessary and sufficient condition on X for Comp (X) being homeomorphic to a non-separable Hilbert space. Moreover, we consider the topological structure of pair (Comp (X‾), Fin (X)) of hyperspaces of X and its completion X‾, where Fin (X) is the hyperspace of non-empty finite sets in X.
