Abstract
The present invention relates to an attachment for a pressure washer wand comprising: a plate having a front end, a rear end, top end, and a bottom end; a first wheel connected to the front end of the plate; a second wheel connected to the rear end of the plate; an angle bracket connected to the plate; a clamp connected to the angle bracket; and optionally a spray wand connected to the clamp. The design of the spray wand attachment of the present invention allows for cleaning a narrow area (only a few inches wide) from the edge of the hard surface. The edger of the present invention is not designed to clean the entire areas of the hard surface because the plate needs to be in contact with the edges of the hard surface, which prevents the device from moving away from the edges.
