FYI....

Armour Detail Supply now have a foam canon.

Probably the biggest let down is the bottle, being PET plastic.
When it comes to the "drop test", PET is not the worst, but not the best either.

From Google AI:

When choosing or using a snow foam cannon for car washing, the bottle material determines whether it will survive a drop onto concrete.

Clear, rigid plastic foam cannon bottles (typically made of Polycarbonate or Acrylic) are highly prone to cracking or shattering when dropped. [1, 2, 3]
The durability of common foam cannon bottle plastics varies significantly when subjected to a drop:


High Risk: Clear Rigid Plastics (Polycarbonate / PC, Acrylic, or low-grade PETG)

• Performance: Very poor impact resistance.
• Why they crack: These plastics are chosen because they are crystal clear, allowing you to see the soap level perfectly. However, they are incredibly brittle. When dropped onto a driveway—especially when filled with 1 litre of water—the plastic cannot flex to absorb the shock. They frequently shatter or crack cleanly across the base or where the heavy brass manifold meets the neck. [1, 2, 3, 4]

Medium Risk: Standard PET / Thick Polyethylene Terephthalate

• Performance: Moderate impact resistance.
• Why they crack: Clear or "smoked" PET bottles (like the ARMOUR DRFT Replacement Bottle) are much tougher than polycarbonate. They will easily survive a 1-metre drop if they are empty or half-full. However, because a foam cannon has a heavy brass head, dropping a completely full PET bottle can still cause a starburst crack at the base or split the threads if it lands awkwardly. [1, 2, 3]

Low Risk: Polypropylene (PP)

• Performance: High impact resistance.
• Why they resist cracking: This semi-flexible, translucent plastic is used in premium upgrades (such as the updated MJJC Foam Cannon PRO V3). Polypropylene naturally bends and deforms under stress, acting like a shock absorber when it hits the ground, making it highly crack-resistant. [1, 2]

No Risk: High-Density Polyethylene (HDPE)

• Performance: Maximum impact resistance.
• Why they resist cracking: HDPE is the milky-white, opaque plastic used in heavy-duty commercial bottles (like the 1L HDPE Foam Cannon Bottle). In drop tests, full HDPE bottles can be dropped from shoulder height or higher repeatedly without cracking. At most, they will scuff or slightly dent, but they will virtually never split or shatter. [1, 2, 3, 4, 5]

Which reminded me of this video, 2 years old now:




Avoid canons with a clear bottle!

Same with buckets.
