I purchased the Griots Foam Cannon (Griot's Garage The BOSS Foam Cannon) primarily because I want to use it directly with their Foaming Surface Wash ( Griot?s Garage Surface Wash) and Poly Gloss (Griot?s Garage Foaming Poly Gloss) containers.

I also purchased the Greenworks GPW2006 (https://www.lowes.com/pd/Greenworks-...her/1000731276) but the connector wasn't compatible. It looked right and I was able to connect the foam cannon, but it wouldn't "lock" and water would shoot all over. I ended up returning the pressure washer.

What am I missing? What do I need to look for to find a compatible pressure washer? Any specific models recommended? Greenworks had been mentioned positively in the forum.
