Need some foam cannon help

Thought it was obvious how it hooked to the pressure washer but it's not. The coupling that came on the cannon will fit into the coupling at the end of the wand but not into the coupling at the end of the hose. My thought was that you remove the wand and replace it with the foam cannon. Is it in fact supposed to hook to the end of the wand? This seems kinda retarded to me but if that's the case then so be it.

Any guidance mucho appreciated.

 

Cannon goes at end of wand, I had to buy a snub nose pressure washer gun so it wasnt so long

 

Thanks. That's what I'll do.

 

Ha Ha, read the reviews on Amazon. A shitload of people thought this hooked up to a garden hose.

 

I thought my foam cannon hooked to a air compressor!
