Abstract: A portable motorized fluid sprayer device is described, having a fluid tank and a pump manifold configured to pump fluid from the tank and into a connected fluid conveying structure (e.g., a hose, wand, nozzle, handle and/or similar structures). The manifold may include an electric motor, a gear pump, a controller, and a battery. Additionally, the fluid sprayer device may allow for spraying fluid with consistent pressure, recirculation of fluid within the tank, a gear pump for spraying or suctioning fluid from the fluid conveying structure, a safety lever, the ability to separate the pump manifold from the fluid tank, and other features.
