It will be appreciated that the features described in relation to embodiments having one or more aspects of the invention are not necessarily features required in relation to the other of the one or more aspects of the invention as will be understood by those skilled in the art. It will also be appreciated that the invention need not be limited to a floor tool that forms part of an upright floor cleaning apparatus. For example, the invention could be embodied on a floor tool which connects to a wand of a cylinder cleaner or the like. The apparatus may also be a wet cleaning apparatus. Furthermore, the cleaning member described with reference to one or more of the embodiments need not be driven by a motor and could be, for example, driven by a wind-turbine.
