    Abstract: Carpet or upholstery cleaning apparatus uiltizing hot cleaning fluid, for instance, water with or without additives, has its heating device located remotely from the suction nozzle so as to simplify the construction thereof and reduce its bulk. In order to insure a constant supply of hot cleaning fluid adjacent the nozzle unit, a bypass line is provided which constantly returns the fluid to the heating element when the fluid is not being impinged on the work. The heating device may be located on a remote carriage which also carries the dirt separating suction tank, a cleaning fluid reservoir, and the cleaning fluid and suction pumps, or it may be mounted directly on the handle of the nozzle unit.

    Abstract translation: 将热清洗液（例如具有或不含有添加剂的水）浸湿的地毯或室内装饰清洁装置具有远离吸嘴的加热装置，以简化其结构并减小其体积。 为了确保在喷嘴单元附近恒定地供应热清洁流体，提供了旁路管线，当流体不被冲击到工件上时，将暂停将流体返回到加热元件。 加热装置可以位于远离的托架上，该托架还带有污物分离抽吸罐，清洁液储存器以及清洁流体和抽吸泵，或者它可以直接安装在喷嘴单元的手柄上。

    Abstract: A powered vacuum mop has the cleaning liquid line arranged as a flexible tube inside the vacuum hose and wand and has a pushbutton valve on the upper end of the wand. Also, an improved cleaning tool has a main housing receiving the wand, and a separator plate under the main housing closes off all the space under the housing except narrow vacuum intake openings along the front and rear edges of the housing. A perforated plate under the separator plate between the intake openings carries a porous scrubbing tool, and a squeegee is arranged in each of the intake openings. The cleaning liquid line leads to a liquid passageway extending through a separator plate and into a perforated tube extending over the perforated plate.
