A device for sweeping a substantially horizontal surface (20) is provided which includes a broom (1) having a handle (7) and a head (2), a valve (5) disposed on the device, and a spray bar (4) movably disposed on the head for directionally spraying a liquid that is supplied to the valve, wherein the valve regulates the pressure of liquid sprayed by the spray bar. The valve can be spring-loaded and/or hand-controlled. The device may include tubing (6) between the valve and the spray bar, which tubing may be positioned internal to the handle or external to the handle. The handle (7) may be used to convey liquid, such as that from a garden hose, from the valve (5) to the spray bar (4). In an embodiment, the head (2) may include water channels (19) and the spray bar may be made integral to the head. The spray bar may oscillate and may take a variety of shapes, including elliptical, u-shaped and straight shapes. The device may further include a reservoir (47) for holding an agent for treating the horizontal surface. |
