Do you want to use different spray modes for different cleaning tasks? The spray gun has a rotating selector switch that allows you to choose between jet, mist, shower, cone, center, flat and full modes. Use the flat or cone mode to spray your lawn, the shower or mist mode to water your plants, and the remaining modes for general cleaning. The sprayer also has a locking mechanism for continuous spraying, so you don't have to constantly keep your hand on the trigger.
