Abstract
A sprayer can include a sprayer body, a reservoir coupled to the sprayer body, a cleaning fluid reservoir coupled to the sprayer body and a pump assembly arranged within the sprayer body and coupled to the reservoir and the cleaning fluid reservoir. The pump assembly can include a pump barrel that defines a central aperture, a piston arranged within the central aperture, a solenoid coupled to the piston and configured to reciprocate the piston within the central aperture during operation of the sprayer, and a manifold assembly coupled to the pump barrel and including a valve member movable between a first position and a second position. The valve member can fluidly couple the central aperture with the reservoir in the first position and fluidly couple the central aperture with the cleaning fluid reservoir in the second position.
