Abstract: A hand-held battery operated sprayer with a rotatable spray lance includes a spray lance assembly and a spray chamber. A motor, a pump, a shutoff valve, a suction hose assembly, a pump inlet hose, a pump outlet hose, a battery pack, and a conductor are disposed in the spray chamber. Water sequentially passes the suction hose assembly, the shutoff valve, the pump inlet hose, the pump, and the pump outlet hose, and flows out of the spray chamber. A rotary axle base is disposed at the front end of the spray chamber. A right-angled rotating shaft is movably connected in the rotary axle base. The rotating shaft is connected to the spray lance assembly. The pump outlet hose can reach a nozzle of the spray lance assembly through the rotating shaft.
