MJJC Foam Cannon V2 Pro Review (After 18 Months of Use)

I’ve was sent an MJJC Foam Cannon Pro (version 2) to test on my YouTube channel well over 18 months now and wanted to share my experience in this in-depth review. I’ll take you through the features, pros and cons, and compare it to some popular alternatives on the market.

MJJC Foam Cannon Pro

Snow Foam Thickness and Quality

Let’s start with the main aspect of this foam cannon that you’re probably interested in: foam quality.

The MJJC Foam Cannon Pro produces super thick foam, and having tried 4 different foam cannons by other manufacturers, this one produces by far the thickest.

It’s important to note that thick foam does not always equal good quality foam. In some cases, the foam produced by the MJJC Pro is actually too thick and heavy, causing it to fall off the car in clumps and reduce the dwell time.

It’s worth noting though that you can adjust the nozzle on the top of the foam lance to decrease the concentration of snow foam so the consistency is a bit thinner and dwells for longer.

Why is the foam so thick?

The MJJC Pro produces thicker foam than most other foam lances for two reasons:

  1. It has a unique gauze filter structure which has a felt filter sandwiched between two thick metal filters. Most foam cannons just have a single metal filter.
  2. It draws up the solution in the bottle faster.

Reason #1 is great. It means you get more foam but without using a higher concentration of snow foam in the bottle. But it doesn’t make nearly as much difference as reason #2.

I personally have compared the MJJC Foam Cannon Pro V2 to another popular alternative, the MTM PF22.2 and measured how quickly the bottle drains. The MJJC Pro V2 drained the bottle 60% faster than the MTM PF22.

This gives the impression that the MJJC produces WAY thicker foam, but it was actually because the MJJC was using more snow foam in the bottle. This means you’ll spend more money on snow foam when using the MJJC, because you’ll need to refill the bottle more often (unless you change your dilution ratio to account for this).

When I adjusted the dilution of snow foam in the bottle to account for this difference in drain rate, there was actually very little difference between the foam thickness of these two foam cannons.

Adjustability and Spray Pattern

The MJJC Foam Cannon Pro V2 is one of the best foam cannons in terms of adjustability.

  • The dial at the top can be adjusted to control the snow foam concentration, and there’s a great range on this too.
  • You can adjust the nozzle blades at the front of the foam cannon to alter how wide the spray pattern is (by twisting the black part of the nozzle)
  • You can also adjust whether the spray pattern is horizontal or vertical (by twisting the red part of the nozzle)

The only thing I will note here, is that the black section of the nozzle (used to adjust the spray pattern width) is quite stiff and will not twist independently of the red section when using one hand. Not a big issue, but something I feel could be improved.

Build Quality

Overall I think that the build quality of the MJJC Foam Cannon Pro is really good. It has a thick plastic bottle that has survived several drops, and the overall construction feels solid. However, in the 18 months of owning it I have noticed one design flaw.

In order to adjust how wide the spray pattern is, you can twist the black section of the nozzle to adjust the metal blades at the front (image below).

These metal blades are prone to warping, and have bent out of place twice now. It can be fixed by dismantling this section of the nozzle and straightening them out, but it’s something I definitely thought I should mention.

This is not an issue that I’ve had with my MTM PF22 foam cannon which has much thicker nozzle blades which are highly unlikely to bend or warp.

Extra Features

In terms of additional useful features, I think the MJJC Foam Cannon Pro V2 is the best option I’ve seen on the market. Here are the key features to note:

  • Wide mouth on the bottle – makes it easy to fill and empty the foam cannon
  • Measurements on the side of the bottle – for easy diluting
  • Slightly over 1 litre capacity – easily covers 2 vehicles
  • Leak-proof bottle – doesn’t leak even when turned upside down
  • Weighted pickup pipe – allows snow foam to be pulled up even if the cannon is tilted
  • Filtered pickup pipe – helps prevents clogging
  • Easy to access the orifice – by removing the adaptor on the back
  • Spare filter and smaller orifice included (for lower powered pressure washers)

Pressure Washer Compatibility

MJJC foam lances have an adaptor which allows them to be connected to the pressure washer trigger.

Different pressure washer manufacturers are compatible with different adapters, so it’s important to select the correct one when ordering. The adapter can be easily unscrewed and replaced if you change pressure washers.

MJJC foam lances are compatible with the following pressure washers:

  • Karcher K Series
  • Karcher HD Series
  • Kranzle
  • Bosch AQT
  • Black & Decker
  • Nilfis
  • Gerni
  • Stihl
  • Kew Alto
  • Lavor
  • Parkside
  • Hitachi
  • Interskol
  • Sturm
  • Ryobi
  • Aftermarket accessories which use a 1/4″ quick connect attachment

Please check the MJJC website for the full and current list of the compatible pressure washers.

Note on Aftermarket Equipment

I personally use the 1/4″ quick connector adapter as I use an aftermarket MTM SGS35 trigger, despite owning both a Karcher and Kranzle pressure washer. Most aftermarket quick release triggers will require this 1/4″ connection, so do not just buy the version which is compatible with your pressure washer brand if this is the case.

For example, if you own a Karcher K4 but are using an aftermarket trigger with a quick release fitting, then you will need to get the MJJC foam cannon with the 1/4″ quick connector, rather than the Karcher K series connector.


Overall I think the MJJC Foam Cannon Pro V2 is one of the best snow foam cannons on the market primarily due to it’s additional features. The foam can be a little thick with some products, but this can be easily adjusted by either using the dial on the top, or putting a lower concentration of snow foam in the bottle.

I think for the price, this is a great option for both professionals and weekend warriors.
