    • An apparatus and method for cleaning a surface. The apparatus includes a frame having wheels and a handle extending outwardly therefrom. A disc plate assembly is mounted on the frame for rotation about a first vertical axis and a nozzle assembly is mounted on the disc plate assembly for rotation about a second vertical axis. The disc plate assembly is rotated at a lower speed than the nozzle assembly. Separate pneumatically-operable motors drive the wheels, the disc plate assembly and nozzle assembly. A skirt extends downwardly from the frame and outwardly from nozzles on the nozzle assembly. The nozzles may be raised or lowered relative to the surface to be cleaned. Fluid is delivered from a fluid source to the nozzles and a vacuum port is provided on the frame to enable dirty fluid to be removed from a chamber bounded by the skirt.
    • 一种用于清洁表面的设备和方法。 该装置包括具有轮的框架和从其向外延伸的手柄。 盘片组件安装在框架上用于围绕第一垂直轴线旋转,并且喷嘴组件安装在盘片组件上以围绕第二垂直轴线旋转。 盘片组件以比喷嘴组件低的速度旋转。 独立的气动马达驱动车轮,盘片组件和喷嘴组件。 裙子从框架向下延伸并从喷嘴组件上的喷嘴向外延伸。 喷嘴可以相对于要清洁的表面升高或降低。 流体从流体源传送到喷嘴,并且在框架上设置真空端口,以使脏污流体能够从由裙部限定的室中移除。
