A wand with boost and mode selections having a high flow capacity and a compact size is provided. The wand comprises a shell, a waterway, and a face module. The waterway includes boost and mode modules. The boost module includes fixed and movable boost sub-modules. The mode module includes fixed and movable mode sub-modules. The movable boost sub-module and the movable mode sub-module are operable to move in a generally longitudinal and circumferential direction, respectively. A first flow passage of the fixed boost sub-module, a second flow passage of the movable boost sub-module, a third flow passage and flow openings of the movable mode sub-module, and first and second outlet passages of the fixed mode sub-module extend in and a flow of water therethrough extends in a generally longitudinal direction. A ratio of a flow coefficient of the wand to a volume of the shell is greater than approximately 0.125.
