Power sprayer

A water delivery system for connection to at least one source of water and for mounting to a sink deck, the water delivery system comprising:

• at least one valve adapted to be in communication with the at least one source of water;
• and
• an output device coupled to the sink deck, the output device having an internal waterway and a spray head, the internal waterway being in fluid communication with the at least one valve and with the spray head, wherein the spray head includes a first outlet defining a longitudinal axis and producing a stream of water from the spray head along the longitudinal axis, and a second outlet having a stationary contact surface facing inwardly toward the longitudinal axis and flared outwardly at a downstream end, the second outlet being continuous and surrounding the first outlet, and a stationary whirl member coupled to the second outlet and positioned upstream from the contact surface, the whirl member including rotationally fixed slots configured to impart rotational movement to water passing to the second outlet, such that water moving to the second outlet is propelled radially outwardly due to centrifuged force for following the contact surface and producing a continuous shield of water from the spray head, the continuous shield of water rotating about the longitudinal axis of the stream of water and being spaced apart from the stream of water.
