A foam generating spray head intended for use in producing so-called snow-foam is disclosed. The head comprises a body (5 figure 2), a chamber 12 formed in the body and being in communication with the atmosphere. There is an elongate foam generating outlet bore 8 formed in the body and extending in a first direction from the chamber to an outlet of the body. There is also a detergent inlet aperture in a surface of the chamber. The inlet aperture is for communication with a reservoir of detergent, and a water inlet for the chamber. The water inlet is configured to direct a jet of water over the detergent inlet aperture and into the chamber in the first direction towards the foam generating outlet bore. The water inlet and the detergent inlet aperture are co-configured so that passage of the water jet over the inlet aperture causes detergent from the reservoir to be drawn into the chamber. The inner surface of the foam generating outlet bore is formed as an aerating surface. |
