A surface treating tool comprising an interconnected cleaning and stripping device for a self contained automated retrieval cleaning apparatus that provides a vacuum recovery and filtration system, with the tool consisting of a rotary brush mounted in an open bottom housing. The brush provides a core having operative connection to a rotating means and includes rows of radially extending resilient flaps carrying at their distal ends peening elements adapted to have contact through the open bottom of the housing with the surface to be cleaned while such surface is being vacuumed. The core can also provide radially extending wire bristles alternately disposed between the rows of resilient flaps.
