A car wash spray device can include a fluid inlet to receive a pressurized fluid from a fluid source. The car wash spray device can also include a first spray nozzle, and a first pressure-sensitive valve in fluid communication with the fluid inlet and the first spray nozzle. The first pressure-sensitive valve can be configured to allow flow of the pressurized fluid therethrough at or below a first pressure. The car wash spray device can further include a second spray nozzle, and a second pressure-sensitive valve in fluid communication with the fluid inlet and the second spray nozzle. The second pressure-sensitive valve can be configured to allow flow of the pressurized fluid therethrough at or above a second pressure. Controlling a pressure of the pressurized fluid can facilitate delivery of the pressurized fluid through at least one of the first nozzle and the second nozzle.
