The MTM Hydro PF22 Professional Foam Cannon is one of the best detailing tools in the industry today!
UPDATE: MTM has added an additional Low Flow Orifice (1.1mm) separately in the box. The standard orifice (1.25mm) is already installed in the cannon. The low flow orifice should be used with lower psi electric pressure washers to create more foam. These will work great for the pressure washers commonly purchased at the big box stores.
One of the main benefits to the Foam Cannon is that you can coat the vehicle with thick, fluffy foam and let the soap do the job of loosening the dirt, and grime! If your vehicle just has a layer of dust on it or isn't very dirty you won't even have to touch the car with a wash mitt! Just pressure wash the foam off the vehicle after it has done the cleaning job for you!
The Foam Cannon produces such a consistent thick foam that it clings to the vehicle, providing the proper lubrication to help you safely wash your vehicle. This will help with properly wash your vehicle and not cause swirls.
