I have 2 of those and they both have the same problem, the Karsher connector has a little 90º twist lock insert in the middle to hold the rubber O-ring in place, that thing is too lose, when you remove the foam cannon from the pressure washer trigger, It in the same direction as the 90º twist lock, so you alway ends up un-twisting and disassembling the o-ring locker. On my first one I lost the o-ring, rendering the entire foam cannon useless. Got a second one, this time decided to put a drop of super glue on that little piece to lock it in place, now it doesn't come off, but connection between canon and pressure washer trigger is rubbish, leaks water everywhere. Don''t get me wrong the products are amazing! Cleans and foams extremely well but they need to go back to the drawing board with this foam cannon.
