ABSTRACT:
A floor tool for use in vacuum cleaning floor surfaces includes a sole plate that has a suction channel formed in it. The suction channel is bounded on at least one side by a working edge for engaging with the floor surface. Lint pickers are positioned alongside the suction channel and are separated from the suction channel by the working edge. The lint pickers are mounted on a surface of the floor tool which is inclined with respect to the plane in which the working edges lie. The sole plate is pivotally mounted with respect to a suction outlet so that movement of the floor tool in a forward and backwards direction alternately brings one of the working edges into closer contact with the floor surface.
