This is the new upgraded MTM PF22.2. The main feature is that it doesn't fall over now!
The actual foam cannon hasn't changed in design but the biggest and most requested change is to the bottle. It's been redesigned to sit flat and not fall over when empty.
MTM made an adjustment to foam cannon kit. It now includes a 1.1mm orifice in the box. The foam cannon comes with the standard 1.25mm installed. You want to use the standard 1.25mm with a Kranzle and most gas pressure washers. The smaller 1.1mm should be used with the lower flowing/less expensive electric pressure washer like the SunJoe, AR, Greenworks, Ryobi, etc. I would strongly suggest you don't attempt to use the 1.1mm orifice on any Kranzle. 1.25mm is already working the pump pretty hard on those much higher flowing machines.
I open the box on every foam cannon that comes from me and swap the crappy zinc plug with a stainless one. It is the standard 1/4" size. I no longer install them to make it easier to swap the orifice. They will be included in the bag with the 1.1mm orifice.
Here is how I use mine:
Add 4-5 oz. Adam's Car Shampoo.
Fill with water, by holding submerged in rinse bucket.
Remove 20" Mosmatic Wand from quick disconnect on Mosmatic HP Spray Gun.
Attach 1/4" Plug/Foam Cannon to Mosmatic HP Spray Gun quick disconnect.
Foam the Car.
