    摘要： Disclosed is a wet/dry carpet cleaner having a large tank assembly for fluids. A bladder containing fresh or cleaning water is positioned in the large tank. Nozzles for dispensing the cleaning water to a brush, a vacuum nozzle for vacuuming and returning soiled fluid to the recovery tank portion of the tank assembly is also provided. The present invention includes the method of securing a brush head assembly pivotably to the chassis assembly and includes the driving motor, rotating brush, and spray mechanism. The pivotal securement results in the weight of the brush head assembly applying a constant force on the brush throughout the entire cleaning cycle, independent of the amount of fluid contained in the recovery tank or the bladder. Also, the method is addressed to configuring and proportioning the bladder to insure a relatively constant load on the nozzle. By balancing the nozzle loading and, therefore, the downward pressure per square inch on the nozzle throughout the cycle compensation results for fluid loss or fluid re-distribution. With the brush loading remaining constant throughout the cycle, consistency is maintained during the entire period while the carpet is being cleaned.

    摘要： Disclosed is a wet/dry carpet cleaner having a large tank assembly for fluids. A bladder containing fresh or cleaning water is positioned in the large tank for dispensing the cleaning water to a brush. A vacuum nozzle for vacuuming and returning soiled fluid to the recovery tank portion of the tank assembly is also provided. The present invention stems from the development of a brush head assembly which is pivotably secured to the chassis assembly and includes the driving motor, rotating brush, and spray mechanism. The pivotal securement results in the weight of the brush head assembly applying a constant force on the brush throughout the entire cleaning cycle, independent of the amount of fluid contained in the recovery tank or the bladder. Secondarily, the present invention is addressed to configurating and proportioning the bladder to insure a relatively constant load on the nozzle. By balancing the nozzle loading and, therefore, the downward pressure per square inch on the nozzle throughout the cycle to compensate for fluid loss or fluid re-distribution; with the brush loading remaining constant throughout the cycle, consistency is maintained during the entire period while the carpet is being cleaned.

    摘要翻译： 公开了一种具有用于流体的大型罐组件的湿/干地毯清洁器。 包含新鲜或清洁水的膀胱位于大罐中，用于将清洁水分配到刷子上。 还提供了一种真空喷嘴，用于将污染的流体抽真空并返回到罐组件的回收罐部分。 本发明源自于可旋转地固定到底盘组件上并包括驱动电动机，旋转刷和喷射机构的刷头组件的开发。 枢轴固定导致刷头组件的重量在整个清洁周期中在刷子上施加恒定的力，而与回收罐或囊中所含的流体的量无关。 其次，本发明涉及配置和配比气囊以确保喷嘴上的相对恒定的载荷。 通过在整个循环中平衡喷嘴负载，并因此平衡喷嘴上每平方英寸的向下压力，以补偿流体损失或流体重新分布; 刷子负载在整个循环中保持恒定，同时在整个毯子清洁期间保持一致性。
