This invention relates to a multi-purpose position sensitive floor cleaning device having two separate and distinct selective modes of operation whereby 180° longitudinal rotation of the floor cleaning device selectively activates one of the two separate and distinct selective modes of operation. The two separate and distinct selective modes of operation are, for example, a scrubbing mode for scrubbing an associated floor and a suctioning mode for suctioning associated liquid from the associated floor.
