In one example, a fluid spraying device includes a chassis, a plurality of wheels connected to the chassis, a spray tip assembly connected to the chassis, and a hopper mounted on the chassis. The hopper is in fluid communication with the spray tip assembly and is configured to be oriented in an upright draining position for draining fluid from the hopper. The hopper includes a bottom side, a top side opposite the bottom side and including an aperture configured to receive and drain the fluid, and a side wall extending at an obtuse angle away from the bottom side to the top side adjacent the aperture to facilitate draining of fluid when the hopper is in the upright draining position. |
