The Best Just Got Better – The Updated MTM PF22.2 Foam Cannon 2024

What’s New?

The latest iteration of the PF22.2 Foam Cannon has made improvements to the ease of use and overall functionality of the unit.

  • All new wide mouth bottle which can be retrofitted to existing MTM foam cannons.
  • Easier filling and emptying due to the wide mouth bottle.
  • Quicker and easier removal of the foam cannon body from the bottle due to the bayonet rather than screw fitting.
  • Quality rubber o-ring to prevent leakages.
  • New weighted pickup tube, allowing for continuous foam output no matter the fluid level or operator angle.


How To Use

You will be using your foam cannon with a pressure washer. For the purpose of this article, we will use Koch Chemie GSF as the subject matter.

  1. To remove the foam cannon body from the bottle, turn the cap anti-clockwise, then gently lift away from the bottle.
  2. Fill the bottle with 950ml of water.
  3. Add 50ml of soap to the bottle (final volume 1000ml)
  4. Secure the foam cannon body back onto the bottle, turning clockwise to lock it down.
  5. Gently shake to mix the soap and water.
  6. Connect the foam cannon to the Spray Gun
  7. You are set to go!

Note: If you have two foam cannon bottles. Fill one with wheel cleaner for wheels and tires and the other with car wash soap.


Tips and Tricks 

  • After foaming the vehicle, empty the remaining soap mixture into your wash bucket and rinse out the bottle. Soap mixture that has been stored does not foam as well next time.
  • It’s a good idea to have a repair kit or replacement filter on hand.
  • When removing or replacing the cap, hold the bottle from underneath while gripping the black adaptor cap and gently twist. Refrain from twisting from the foam cannon body itself.



Priced at roughly $150, it's not the cheapest option. But remember, you'll have this for a long time, making it a worthwhile investment for a full car detailing setup.
