ABSTRACT:
A floor tool for use in vacuum cleaning floor surfaces includes a sole plate for engaging with a floor surface, a supporting body for the sole plate having means such as wheels or rollers for allowing the body to ride along the floor surface and an outlet conduit for coupling to a wand of a vacuum cleaner. The outlet conduit is mounted to the support platform by a connecting arm, a first end of the connecting arm being pivotally connected to the outlet conduit about a first axis and the second end of the connecting arm being pivotally connected to the supporting body about a second axis. The first and second axes are substantially parallel to one another. Fluid flow from the sole plate can be carried by a flexible hose or by the connecting arm itself.
