I have that foam cannon but I get much better results using it with a karcher K4.
I've read that most cannons consider low pressure to be 90 bar, the one I use has 70 and I still get a good foam. Although the foam used makes a difference because Bilt Hamber for example isn't known for being foamy.
However, the Greenworks is ridiculously expensive for what it is. Brand new the unit is .c £149 (can go down to £100 to £125 on deal) but that's without any batteries or charger - being 40V batteries they're expensive and you need min 1 x 4aH. You're looking at £250 to £300 for the unit with 1 x 4aH battery and charger
It's 144Wh, just an FYI but I would stay away from any unofficial battery as I ordered one from eBay and I've had issues where the machine runs for 5 seconds before cutting out. Usually, I don't bother with unofficial batteries but the listing stated it used Sony or LG cells and had all protection circuitry.
The battery I was looking at on eBay was directly from Greenworks themselves. However if the battery is over 100Wh I will most likely be charged for a dangerous goods notice costing an extra £ 25.
Just to confirm it does use the 1/4 quick connector for the foam cannon connection?
See my edit regarding the 1/4 quick connect. Annoyingly, the new update for my phone is making the keyboard enter new line returns hence why my post was gigantic.
Thanks do you have a link to the adapter needed which fits the 1/4 Lance? Also maybe I should buy two 2.0Ah batteries instead of the one 4.0Ah which should be under 100Wh thereby avoiding the extra £ 25 expense.
