I found a nice kit at Lowes that makes a comfortable way to attach the foam cannon to the pressure washer hose without the wand. Here
THE BOSS Foam Cannon features a precision machined, stainless steel manifold for a lifetime of rich foam. Includes an industry first Auto-Mix system which dilutes your preferred BOSS Foaming concentrate without pre-mixing. Simply thread Griot's 35 oz bottle onto the inner threads, connect your pressure washer and deliver a blanket of dry, rich, high-clinging foam over your vehicle.

The Snubby makes shooting thick car washing foam all over your car manageable and easy for all with a compact design so you dont have to use that long and unwieldy pressure washer wand! Using a pressure washer and foam cannon is the best way to lay down thick car washing foam, however, that long pressure washer wand can be difficult to manage and control. They are long, unwieldy, and risk scratching your paint if you get too close.
