    • A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation is provided. The cleaning apparatus includes a base portion for movement along the surface and a handle pivotally connected to the base portion. A solution tank for supplying a flow of cleaning solution to the surface is removably mounted to one of the base portion and handle. A recovery tank is removably mounted to the handle. A suction nozzle is secured to the base portion. A suction source is located downstream of the recovery tank in fluid communication with the suction nozzle for generating suction to draw dirt and liquid through the suction nozzle and into the recovery tank. A suction conduit is fluidly connected between the recovery tank and the suction source. A suction shut off device is operatively connected to the suction source to shut shutoff suction through at least a portion of the suction conduit upon the handle being pivoted down a predetermined distance to a first position.
    • 提供了一种用于清洁其中清洁溶液被分配到表面并且在连续操作中基本上同时在表面上被污染地提取的表面的清洁装置。 清洁装置包括用于沿着表面移动的基部和可枢转地连接到基部的手柄。 用于将清洁溶液流供应到表面的溶液罐可移除地安装到基部和手柄中的一个上。 回收罐可拆卸地安装在手柄上。 吸嘴固定在基座部分上。 抽吸源位于回收罐的下游,与吸嘴流体连通,用于产生吸力,以通过吸嘴吸入污物和液体并进入回收罐。 吸入管道在回收罐和抽吸源之间流体连接。 抽吸切断装置可操作地连接到抽吸源,以在手柄沿预定距离向下枢转到第一位置时通过抽吸管道的至少一部分闭合截止抽吸。

    • The cleaning apparatus includes a base portion for movement along the surface and a handle pivotally connected to the base portion. A recovery tank is removably mounted to the handle and has a front end. A lid covers the recovery tank and has an inlet opening for directing dirt and liquid into the recovery tank and an outlet opening located at the front end of the recovery tank. A suction nozzle is secured to the base portion and fluidly communicates with the inlet opening of the lid. A suction source fluidly communicates with the outlet opening for drawing dirt and liquid from the surface through the suction nozzle and into the recovery tank. A partition device is positioned between the outlet opening and the inlet opening and extends down within the recovery tank a sufficient distance to prevent the liquid from flowing from the inlet opening to the outlet opening.
    • 清洁装置包括用于沿着表面移动的基部和可枢转地连接到基部的手柄。 回收罐可拆卸地安装在手柄上并具有前端。 盖子覆盖回收罐,并具有用于将污物和液体引入回收罐的入口和位于回收罐前端的出口。 吸嘴固定在基座部分上并与盖子的入口开口流体连通。 抽吸源与出口开口流体连通,用于通过吸嘴从表面吸入污垢和液体并进入回收罐。 分隔装置定位在出口和入口之间,并在回收罐内向下延伸足够的距离,以防止液体从入口开口流到出口。
