If you want to effectively clean your vehicle while lessening the chance of swirl marks or scratches, then a foam cannon is your best solution. Because it allows you to easily cover your entire vehicle with thick foam that doesn’t quickly run off, it loosens dirt, bird poop, and other surface contaminants on its own rather than having to agitate with a wash mitt.
With a foam cannon or lance, you will need to attach the hose from a pressure washer to work correctly. While a foam “gun” only requires a standard garden hose, you don’t get that same benefit of the thick standing foam that’s associated with a cannon.
So if you have a pressure washer or are will to get one, nothing beats washing a vehicle with a good foam cannon. There’s a reason this product is so popular with auto enthusiasts. Without further ado, here are 10 of the best foam cannons on the market today.
Top 10 Best Foam Cannons for Cars and Trucks
1) TriNova Foam Cannon
If you want to own a foam cannon that is exceptionally easy to use, then this model is the one for you. All you need to do is fill up the reservoir bottle with soap, and then connect the device to a pressure washer to get the spray you need.
You can then soak your ride with all of the required suds to get rid of the toughest grime, insects, and other road-based contaminants. This model offers a wider neck to resist issues with cracking that are common with some of the competition. Arguably the best foam cannon available today, although slightly more expensive than others.
2) MATCC Foam Cannon
If you want an upgraded experience with your car cleaning chores, then this foam cannon delivers the goods. It features a heavy-duty brass core that is heavy and thick, with a tight plastic container, which reduces vibration while working.
There is a filter end on the tube as well that prevents particles from hitting your vehicle from the water or soap. You do need to have a pressure washer that provides 2 GPM and 1,450 PSI to use this product successfully.
3) RULER Foam Cannon Lance
As one of the best foam cannon values around, the RULER model is super easy to operate. Simply fill the reservoir with your favorite car wash, connect your pressure washer wand to the 1/4″ quick connector, adjust the foam volume, set you nozzle pattern, and start shooting thick, luxurious foam on your vehicle.
Works well with 1000 to 3200 PSI pressure washers that put out between 2.0 and 5.3 gallons per minute. With a heavy duty brass core, expect this cannon to last for years.
4) McKillans Snow Foam Cannon
Using car soap and a pressure washer, this snow foam cannon provides a superior cleaning process that gives you a delicate, yet deep cleaning experience. Your vehicle will sparkle and shine with only a few minutes of work thanks to the extra surface lubrication this device adds.
The bottle is a robust, translucent plastic that allows you to see how much car shampoo you have left while working. You can adjust the spray and angle with an easy-access controller that uses raw brass and copper instead of recycled materials to create the results you want.
5) Weirran Foam Cannon
This foam cannon gives you excellent perfect performance every time. It provides a thick, sticky foam using a 0 to 90 degree jet pattern while giving you a clean rinse. Just twist the soap control knob anywhere from max foam to no foam, and it will let you get the job done.
The nozzle is made from brass, while the remainder of the unit is plastic. Requires a pressure washer capable of at least 1,000 PSI. It is affordable, durable, and ready for home use straight from the box.
6) Fasmov Foam Cannon
This popular yet inexpensive foam cannon features a 1/4-inch quick disconnect adapter that makes hookup a breeze. It only needs 1,000 PSI of minimum pressure (and 2.0 GPM) to operate, and this bottle provides one full liter for your soap.
You can adjust the spray nozzle to create an accurate mix so that the foam you create gives you the results you want. There is an adjustable vertical jet nozzle for you to use a side-to-side application process as well.
7) Chemical Guys Foam Blaster
While not technically a foam cannon, the Chemical Guys foam gun is probably the best alternative to a proper foam cannon when you don’t own a pressure washer as it connects to any standard garden hose. You can make quick work of your vehicle cleaning with on demand suds that break up dirt and won’t scratch your paint.
This model gives you the option to control the concentration of your foam to tackle light or heavy washing tasks. Since you don’t need any additional tools to get to work, this investment is one that makes a lot of sense for many car owners.
8) Twinkle Star Foam Cannon
With this adjustable foam cannon, spray thick suds on your vehicle with the help of a 1,000 to 3,600 PSI pressure washer that’s capable of at least 2 gallons per minute. The spray nozzle is adjustable to give you the proper mixing that you need.
All you need to do is adjust the knob on the top of the unit to get the spray pattern that you want. In addition to washing cars, use this tool to clean your windows at home, spray down your roof, or anything else that could benefit from a deep cleaning experience.
9) Foseal Snow Foam Lance
This model is another generic option that connects to your pressure washer, but it delivers consistent results. This foam cannon works with almost any pressure washer that’s capable of at least 1,000 PSI and 2.0 GPM (except the Troy-Bilt 3100 XP) and has a 1/4 inch connection.
Simply add car wash shampoo and a bit of warm water to the 1 liter bottle, connect your pressure washer hose, adjust your foam quantity and pattern, and go.
10) Autown Foam Cannon
All you need to do with this foam cannon is fill up the reservoir bottle with soap, click it onto your existing pressure washer trigger or lance, and then spray away. The mixture is noticeably thick at its strongest setting, giving you the option to manage multiple chores at once.
