Abstract
A paint sprayer for spraying a fluid comprises a housing that houses a motor, a pump, and a fluid passage. A handle is coupled to the housing and a paint cup is coupled to the handle for storage of a fluid. The handle is positioned between the housing and the paint cup. The paint sprayer has a center of gravity region. A longitudinal axis of the handle and a longitudinal axis of the paint cup are aligned with the center of gravity region of the paint sprayer. A gripping zone of the paint sprayer is also aligned with the center of gravity region.
