ABSTRACT:
A portable, steam weed killing apparatus designed to be environmentally friendly, economical, fast acting and used by an individual standing in an upright position. The apparatus is intended for killing weeds and unwanted plants in gardens, flower beds and along sidewalks by application of concentrated heated water or steam thereto. The apparatus includes electrically powered, portable steam generating unit containing a water reservoir, an electric pump and an electric steam heater. The apparatus also includes an elongated, rigid guide bar with a weed cover attached to its distal end. A flexible hose delivers steam from the steam generating unit to the weed cover. During use, the weed cover is placed over the undesired plant and the steam generating unit is operated to deliver a concentrated amount of steam to the plant located inside the weed cover. In another embodiment of the invention, the steam generating unit includes a super-heating steam unit which provides saturated, super-heated steam for greater killing effect.
