A Foam Cannon is a must have tool for auto detailing. Make any foaming product spray on with crazy thick foam. This is used for applying soap to a vehicle during the pre-wash, applying soap for the contact wash, applying wheel cleaner, and any other way you can dream of using it. This foam cannon requires a pressure washer system that can support this tool. I recommend at least 1.2 gallon per minute water flow and a minimum of 900 PSI pressure. For low output electric pressure washers use a 1.1mm orifice in the foam cannon. Use a 1.1mm orifice in a larger high output electric washer to achieve crazy thick foam but beware this will OVER WORK the pressure washer and possible SHORTEN the lifespan and VOID any warranty. Too small of an orifice will also increase the amperage needed to run the pressure washer beyond the standard 15 amp circuit plus most people have in their garage requiring an upgraded dedicated 20 amp circuit. Check out a few of my pressure washer videos prior to going all in on this. DO NOT use a 1.1 orifice in a large high pressure/ output gas pressure washer. Use the appropriate orifice size for your machine.
All of these pressure washer options are good. With tools you get what you pay for. The top of the line is commercial grade and the entry level is for part time residential use.

#3 BEST FOAM CANNON UNDER $20
Foam cannon A great economical knock off foam cannon that will get the job done but wont leave you proud of what you bought. Questionable materials and build quality. I use it for harsh chemicals and as a beater that I don’t need to take care of. I have a few of them.
