A device for generating a foam which might be used, for example, as a cleaning fluid. As depicted, the device comprises structure which accepts a combined fluid, such as water, soap, and air, and passes it through a pair of turbulators in series. As it enters the first turbulator, the fluid is forced to turn through a turbulence-generating angle. The first turbulator may be substantially filled with a turbulence-generating material providing a plurality of randomly sized and randomly oriented interstices through which the fluid must pass in traversing the turbulator. The turbulence-generating material might, for example, comprise a material such a metallic or plastic turnings which are gathered together and fixed in place. Fluid discharged from the first turbulator then travels in a relatively quiescent flow through a pipe or tube to a second turbulator which may employ the same type of material to generate additional turbulence in the flow and thus assure complete mixing. Preferably, the material in the second turbulator is packed at about the same density as that in the first turbulator, but the second turbulator has a larger volume to allow the foam to expand. The device may be mounted upon a movable cart which also supports a battery-driven air compressor, a source of soap, and hoses and lines for connection of the device to a water spigot or hose bib. The cart may also support a battery and a battery charger, as well as a rinse hose and a wax applicator.
