  • Rotary cleaning head having indirect fluid application
    Patent number: 9295366
    Abstract: A rotary cleaning device having a plurality of flush pad extractors can provide improved debris removal and reduced residual material. More specifically, a rotary cleaning device can include a plurality of flush pad extractors which are oriented generally circumferentially about a common rotation axis. These unique flush pad extractors can include a fluid applicator and a vacuum member oriented behind the fluid applicator such that during operation of the device the fluid applicator contacts a surface to be cleaned prior to contact by the vacuum member. In accordance with the present invention, the fluid applicator provides passive delivery of fluid to the surface to be cleaned. Passive delivery of fluid allows for reduced fluid usage and more controlled and even distribution of fluid across a surface without overwetting.
