A car wash device includes a vessel, pump, brush, hose, flow control device and fittings. The brush has a nozzle. The hose is matable to the brush and to the vessel. The brush is matable to both the hose for the vessel and a high pressure water source. A flow control device has a low pressure position for use when the brush is mated to the vessel and a high pressure position when the brush is mated to the high pressure water source. Liquid may be pressurized by the pump and flow from the vessel and through the nozzle for use when the flow control device is in the low pressure position. Alternatively, water flows from the high pressure water source through the nozzle for use when the flow control device is in the high pressure position. A brush for the car wash device is also provided.
