Abstract: Embodiments of the invention provide a cleaning apparatus, such as a battery- powered vacuum cleaner, that has a body and a cleaning wand. The apparatus operates in a multiple power mode, uses a wireless system to allow an operator interface to be provided on the cleaning wand and/or uses a motion detector on the cleaning wand to operate the cleaning apparatus in an intelligent manner. In cases where the cleaning apparatus is a battery-powered apparatus, the use of a multiple power mode, wireless system and/or a motion detector helps to extend the life of a battery.

Abstract: An apparatus (10) and method for cleaning fabrics, floor coverings, and bare floor surfaces (25) utilizing a soil transfer cleaning medium (62, 64) is disclosed. A method of mechanically removing soil from a surface (25) intended to be cleaned includes the steps of successively and repeatedly: wetting a portion of a cleaning medium with a cleaning liquid; extracting any soil and at least some of the cleaning liquid from the previously wetted portion of the cleaning medium (62, 64); and wiping the surface intended to be cleaned with the portion of the cleaning medium (62, 64) so as to transfer soil from the surface intended to be cleaned (25) to the cleaning medium (62, 64). Portable and vehicle-based devices may be utilized to practice the method of cleaning.

Abstract: 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 (10) is disclosed having a cleaning implement (34) in selective wiping contact with a surface (20) to be cleaned, a cleaning solution dispenser (36, 38) which selectively wets with a cleaning solution (14) a portion of the cleaning implement (34) or a portion of the surface (20) or both, a first selectively controllable vacuum extractor tool (56, 58) which when operating removes some of the dispensed cleaning solution (14) and soil from the cleaning implement (34), and a second selectively controllable vacuum extractor tool (54) which when operating removes soil and some of the cleaning solution (14) directly from the surface (20) 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.
