I don't know why every single professional wand isn't sold with a few basic common sense items, like stainless jets, inline filter at the valve QD connection, You don't really need filters down on the jets themselves, a insulated sol. line for no burns, a hand grip sleeve that doesn't slide when the tube get warm, a trigger that doesn't cause carpel tunnel after 8 hours of use etc...
btw: there is no proof a shielded spray jet 3.5" off the carpet preserves any more heat than a jet 1.5" off the carpet with open spray. Sounds like a test for the candy thermometer at
MikeyFest.
I'm in the same camp, gotta be able to lean to the side a bit and "see" my jets while actually cleaning.
Also the only way a 2 jet wand pointing straight down cleans better than a multi jet wand at an angle, is agitation in the form of impact or pressure of the spray hitting straight down and generally the jet orifice being larger.
Try this: turn your angled jet wand pressure up by 100-150 psi, it will clean better, but not risk over wetting due to the angle and the sheer as it pushes the suspended soil towards the vacuum slot.
The PMF wands (easy
glide/magic glide) have the 2 jets too close together, they should be spaced further apart for a more even pattern, it's too heavy in the center and not heavy enough on the flanks.
Also the way the tube joins the head is a turbulent airflow nightmare.
