These ones that are in the brush head atm are from xline, 4 times I've been back to change them over from them but the spray never looks right, ill have to post a video of it tomorrow to fully explain what I mean but it almost looks like there's a blockage or something in one, I've ordered these other jets from cleaning spot, only need one but bought 2 so I have a spare, not going back to xline with it as I've been there 4 times now and I've still got the same problem, not sure if there barbed or not if I'm honest didn't say anything about that in the description
