Well here's a comparison of the 2 cannons MTM offers. I first learn about a new offering from MTM a couple of months ago digging around on AG when I needed to purchase a new pressure washer. My old Karcher K2.28 bit the dust after 5 hardy years and I purchased a newer Karcher K5.740 model.
While researching the new fittings I'd need to make the Karcher X series work with my old MTM Hydro that was built for gas pressure washers (but many have bought it to use with electrics, including me) I came across a newer model MTM foam cannon that was electric specific and on it's specifications listed a lower minimum PSI and GPM requirement. Intrigued, I ordered one up to test it out. The old model is MTM model number 14.0263, the newer, lower PSI & GPM requirement model is 14.0349.
Here's some pics to show the new vs. old.
New as it comes in box, note the paperwork states it's lower pressure, and it comes with a Karcher bayonet fitting already attached:
Here's a close up of the head unit, it has a tag stating the lower pressure requirements as well. My original had no such collar tag:
The next pic shows my original MTM Hydro cannon with the new one's different shaped bottle. The new bottle is more square at the top, the bottle feels a bit thinner in material strength, and the threads aren't a dead nuts match to the gun like the old bottle. Not sure what all that's about??? Note my old cannon has a bunch of fittings that I researched here to make sure it would work with my Karcher X series K5.740 Pressure Washer:
Next up is a pic of the inner orifice of the two head units side by side. I had initially thought that perhaps this orifice would be smaller, and that would be the difference between the 2 when dealing with a smaller PSI and GPM pressure washer. Given the pic, it's too close to call. The one on the left seems a shade bigger, but then, it's also a shade closer to the camera. I did the best I could holding them, they wouldn't hold still in my hand dead even, and I had to angle them just right to get both in the pic. Zoom in really close to compare:
Last is a comparison of the attachments to go to my Karcher PW. The site I purchased it from claims on the webpage devoted to the cold water electric MTM gun that the black bayonet fitting that is pre-attached works with the X Series PW, but on Autogeek, I found some threads specifically about the X Series PW that claimed I needed the yellow fitting to make it work:

I didn't even mess with it after reading that thread. Took the preinstalled fitting off and fitted the new cannon with another quick connect. This had the benefit of letting me do a quick change between the old and new MTM Hydro cannons.
At last, the foam pics!
The first set of pics is from the older MTM gun that I used on my wife's 2008 Infiniti G35 sedan. We affectionately call it "The Bus" because it's the preferred vehicle to transport our 13 month old daughter around in.
To be fair, both tank reservoirs were filled with hot tap water and 2oz of Chemical Guys Maxi Suds II, which seems to be a favorite for economical foam cannon use, and they were thoroughly mixed.
Notice it's foam, but soupy and runs off the paint quickly. The Old MTM also had a bit of an advantage in my mind, because I sprayed it onto a dry vehicle, so there was no water to dilute the soap, or act with the LSP to sheet it off.
Here's another shot:

Next are some stills of the newer low pressure MTM Hydro cannon built specifically for the low pressure and flow requirements of an electric pressure washer:
And a video of it too:

I don't think there's any doubt in my mind it works much better at creating a foam that will dwell better, and as of today, it's $10 bucks cheaper to boot!
