Thanks for these pictures. It helps. Hope it works well for you.
I think I would prefer the jets be placed closer to the swoop side of the vacuum ports so the spray would be picked up sooner in each revolution. It looks like you may have changed the jet position from what you started with as the jets looked like they were previously more centered between the vacuum slots. If anything, rather than the jets center spaced, I would have cheated closer to the swoop side of the slot.

Rotovac has been all over the place with their jet placements. It shouldn’t be that hard to figure out.
The Hoss, as I recall, played around with their spray bars. Some bars were full length and others were not. I think too much flow may have been the issue?
Mytee seems to have good jet to vacuum port placement, and the Junior looks good from the bottom, but it’s about 10 pounds or so heavier than the 360i quad, and I don’t believe the Junior has a telescoping arm. Being able to shorten and lower the arm is very desirable for using it on steps.
