Abstract
A model for cleaning a graph with brushes was recently introduced. Most of the existing papers consider the minimum number of brushes needed to clean a given graph G in this model, the so-called brush number b(G). In this paper, we focus on the broom number, B(G), that is, the maximum number of brushes that can be used to clean a graph G in this model.
