Claim:
A hand-held device for applying a layer of fluid droplets, said device comprising: a housing including a fluid reservoir; an inlet port in the housing for receiving pressurized fluid; a rotatable brush roll including a plurality of bristles, the brush roll being configured for rotation along an axis positioned to have a selected spatial relationship relative to an exit window in the housing; a conduit for delivering the pressurized fluid to the bristles in the brush roll; at least one flipper element positioned to contact the tips of the bristles extending over a corresponding section of the rotatable roll so that fluid collected therein is propelled through the exit window in the housing with a pattern at least in part based on the selected spatial relationship between the rotation axis of the brush roll and the exit window; an outlet port for draining fluid that accumulates in the reservoir; and a shutter coupled to a trigger assembly for selectively opening and closing the exit window in response to respective commands from an operator of the device.
