The Wagner airless paint sprayer is ideal for large outdoor projects such as painting the exterior of a house. Because the airless paint sprayer applies paint by means of a piston, it is powerful enough to directly apply thicker paints like latex in larger quantities than regular air-powered paint sprayers. The Wagner airless paint sprayer model also comes equipped with a specialized spray tip that can be turned 180 degrees in order to make it easier to unclog the sprayer's nozzle.

The power of an airless paint sprayer also has its own drawbacks. The sprayer's piston drives the paint out with such force that it emits substantial amounts of paint dust and small paint particles from the sprayer nozzle along with the stream of paint. This is why airless paint sprayers are better suited for use outside where these small paint particles can't settle on interior walls. Airless sprayers are also noisier than air-powered sprayers because of the motor and piston apparatus and need more maintenance and upkeep because they have more moving parts.
