With 4 jets same size as in 2 jet wand any more pressure would have flooded the carpet, even at 250 - 300 it was the perfect amount - the bypass i like for emptying the cold from the solution lines spesh on longer runs so can start cleaning hot - feel its also safer to let Prowler warm up with valve slighlty cracked.
Looking for a wand similar to westpak tho bit shorter I am no short stop at 6ft but the westpak must have been designed by someone around 6'4" to make it fuly comfortable to use
