    摘要： An apparatus and method for cleaning fabrics, floor coverings, and bare floor surfaces utilizing a soil transfer cleaning medium is disclosed. A method of mechanically removing soil from a surface 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; and wiping the surface intended to be cleaned with the portion of the cleaning medium so as to transfer soil from the surface intended to be cleaned to the cleaning medium. Portable and vehicle-based devices may be utilized to practice the method of cleaning.

    摘要： An air sweeping apparatus having a head assembly, a debris conveyer and a receptacle. The head assembly includes a front skirt which is selectively positionable away from a surface to be cleaned to enable debris of different densities and sizes to be collected. After the front skirting of the head assembly is moved past debris, the debris becomes entrained within a flow of air formed by a line of pressurized air as it traverses the surface and the interior surface of the main chamber of the head assembly. Preferably the air flow in the head assembly is skewed with respect to the direction of travel to urge the entrained debris towards an output end of the main chamber. When debris reaches the output end of the main chamber it is transported to a debris receptacle by a low pressure conduit which discharges entrained debris into a first hopper or bin. As the debris enters the first hopper, the heavier material settles and lighter, entrained material is directed through a filter element and onto a second hopper or bin. The second hopper includes a separator which is used to remove light particulate matter. After emerging from the separator, the air stream enters an air handling device (typically a motorized fan surrounded by a shroud) where it is pressurized and directed to the input portion of the head assembly. A portion of this high pressure air flow is directed back towards a third hopper or bin in the receptacle where it is passed through a filter to remove fine particulate matter and exhausted.

    摘要翻译： 一种具有头部组件，碎屑输送器和容器的空气清扫设备。 头部组件包括前裙部，其可选择性地定位成远离待清洁的表面，以使得能够收集不同密度和尺寸的碎片。 在头部组件的前围板移动通过碎屑之后，当碎片穿过头部组件的主室的表面和内表面时，碎屑被夹带在由加压空气线形成的空气流中。 优选地，头组件中的空气流相对于行进方向倾斜，以将夹带的碎屑推向主室的输出端。 当碎片到达主室的输出端时，它通过低压管道输送到碎片容器，将夹带的碎屑排放到第一料斗或料仓中。 当碎屑进入第一料斗时，较重的材料沉降并且较轻，夹带的材料被引导通过过滤元件并进入第二料斗或料仓。 第二料斗包括用于除去轻微颗粒物质的分离器。 在从分离器出来之后，空气流进入空气处理装置（通常是由护罩包围的机动风扇），在那里加压并引导到头部组件的输入部分。 该高压空气流的一部分被引导回到容器中的第三料斗或料仓，在其中它通过过滤器以除去细小的颗粒物并排出。
