Create loads of foam to loosen dirt and grime. The MTM Hydro Foam Cannon turns a few ounces of car wash soap into high-volume foam that loosens dirt, grime, and abrasion particles on your vehicle’s exterior. This reduces swirling and the risk of scratching while scrubbing with a mitt or brush. Chemical injection knob controls foam output. Adjustment controls on the MTM Hydro Foam Cannon allow you to control the amount of foam being created. You can also switch between vertical and horizontal spray patterns. Two orifices are attached for maximum pressure washer compatibility. In addition to the standard 1.25 mm orifice, the MTM Hydro has a 1.1 mm orifice for lower-flowing pressure washers. Both require a minimum of 1,100 PSI to operate properly. The tank is ergonomically designed for ease and comfort. The tank on the MTM Hydro is easier to hold and less likely to drop than past models. It weighs only 1.5 pounds, making it highly mobile. Cost-effective and highly efficient. The 32-ounce tank requires only 2-3 ounces of soap for use. The rest can be filled with water. This saves product waste and stretches your soap supply. A replaceable filter prevents grit from entering the soap stream.
