摘要 A surface cleaning device having a steering assembly is provided. The surface cleaning device includes a foot, a handle assembly with a user manipulated handle, and a steering assembly coupling the handle assembly to the foot. The steering assembly defines an open path between the handle assembly and the foot and includes a means for biasing the foot with respect to the handle assembly. Movement of the handle assembly stores energy within the biasing means so that the biasing means exerts a corresponding force on the foot.
