Abstract: A spa sprayer contains: a body and a water spray unit. The spray unit including a spraying seat, a lid, and a cavity defined between the spraying seat and the lid. The spraying seat is mounted on an end of the body away from the motor and has an impeller received in the cavity. The lid has at least one inlet and two opposite outlets which are in communication with the cavity. The lid further has a spacing rib, an inflow space formed inside the spacing rib, an outflow space formed outside the spacing rib, and multiple tilted guide ribs. A tilted direction of the multiple tilted guide ribs corresponds to a rotation direction of the impeller, each of the multiple tilted guide ribs has an oblique angle, and the lid further has two stop shoulders extending from the two opposite outlets.
