An apparatus performing multiple different cleaning operations for cleaning fabrics, floor coverings, and bare floor surfaces is disclosed. A device according to the present invention selectively utilizes soil transfer and solution extraction technology. In one embodiment, an apparatus is disclosed having a cleaning implement in selective wiping contact with a surface to be cleaned, a cleaning solution dispenser which selectively wets with a cleaning solution a portion of the cleaning implement or a portion of the surface or both, a first selectively controllable vacuum extractor tool which when operating removes some of the dispensed cleaning solution and soil from the cleaning implement, and a second selectively controllable vacuum extractor tool which when operating removes soil and some of the cleaning solution directly from the surface intended to be cleaned. A method of use of such an apparatus is also disclosed. Portable and vehicle-based devices may be utilized to practice the different methods of cleaning.
