The IDROBASE Foam Cannon is a good value option foam cannon. Installed 1.25 orifice as well as a 1/4” plug, this quick connects to any trigger with a 1/4” coupler. Lightweight materials used, this is foaming in its most simplistic form.
The reality is this foam cannon matches the price. Some have purchased this previously and had it in professional use for years. Some prefer to dispense certain products through this and save their more costly units as ‘soap only’.
Not necessarily rebuildable, limited ability to adjust foaming mixture, this Cannon makes sacrifices for price point.
