The Dyson Articulating Hard Floor Tool is designed for improved pickup on hard floors, with bristles that prevent scratching or marking on wood or delicate floors. It"s designed with two pivoting points, one on the neck, (for left and right motion), and one on the base of the tool, (for up and down motion). It pivots 180° and has an ultra-slim profile to clean hard to reach spaces more easily. The articulating hard floor tool works on all Dyson upright and canister models.
