It depends on the soiling and the level of soiling, i think if its everyday foot traffic, the mw/rw will be fine, but if its like some of the engineering factories we do, when all the factory staff walk through the offices day in day out, i just don't think they'll cut it, well i dont think, i know! i have owned mw and i have a rw, which now gets used for scrubbing in pre spray on carpets, for which it is very good for!!!!
