Patent ID: 7979940

Claim:
A portable apparatus for treating a surface and comprising: a handle having a proximal portion for holding in a person's hand and a distal portion for delivering a carrier fluid to the surface; a carrier fluid supply fitting at the proximal portion for connection to a source of carrier fluid; a housing at the distal portion of the handle; a treatment material cartridge mounted to said housing for rotation on an axis and containing treatment material in liquid form, said cartridge having an outlet opening; a nozzle at the housing, said nozzle having an inlet to receive said carrier fluid, and said nozzle having an outlet to discharge said carrier fluid in a stream having a discharge direction; a carrier fluid delivery passageway from said supply fitting to said nozzle inlet; a wheel mounted in the housing for rotation on a second axis in the housing; and a plurality of surface treating elements circularly spaced around the wheel, wherein said nozzle is adjustable to change said carrier fluid stream discharge direction relative to said axis of the cartridge, wherein the nozzle is sufficiently adjustable to cause the discharge direction of carrier fluid from the outlet to impinge the treating elements and thereby rotate the wheel on the second axis, and wherein the nozzle, the cartridge, and the wheel are arranged to enable a discharge direction of the carrier fluid to impinge portions of the cartridge and the treating elements to enable simultaneous rotation of the cartridge and the treating elements on their respective axes.
