Battery-powered spray wand

Abstract

A system, apparatus and method are provided for spraying liquid contained in a reservoir remote from said apparatus. The spray apparatus includes a housing in which a pump is positioned. The pump has an inlet and an outlet. An electric motor positioned within the housing drives the pump when a power supply located in the housing selectively provides power to the motor. A flexible intake hose connected to the inlet of the pump extends out of the housing to provide a path for liquid to flow from the remote reservoir to the pump. A discharge device in fluid communication with the outlet of the pump discharges liquid from the apparatus in a desired spray pattern. The housing also includes a hose compartment for storing a predetermined length of the intake hose when the apparatus is not in use so that the intake hose can be extracted from and inserted into the hose compartment. The spray apparatus may further include an extension for varying the distance between the discharge device and the housing. Additionally, a portion of the housing may pivot with respect to another portion of the housing.
