ABSTRACT:
A liquid spaying apparatus is formed by a molded plastic generally rectangular container having a forward surface contoured for contacting the back of a user in backpack fashion. A wheel and axle assembly secured to the forward lower portion of a container support panel in cooperation with a handle on the container permits movement of the apparatus in two wheel dolly fashion. An on board battery drives a motor/pump assembly for spraying liquid through a manually controlled wand.
