The unit is a 47, I believe it was built in 2006 or 2007.
Using a 15 flow Greenhorn at 500psi it usually maintains about 190-200. The tile tool has more pressure but less flow (2x 02jets) and I haven't really used the tile tool with it. The hydrokinetic uph tool really gets hot!
I've often wondered if the tools heat up more, ie the uph tool and the pipe on the wand, because the vacuum isn't moving enough air and the water is on the pipe more. I've run 200+ through my wand before with my truck which has awesome airflow and the tools never feel that hot.
Which reminds me, at that water flow, we would go through the fresh water . We started using one of the Ti wands from Cal tools and it had 10flow, that made the fresh water last longer. There's only a 100gal tank on the truck and 15flow ate through that pretty quick.
so the list of tweaks I'd do to my friends Cleanco is:
rig for 2.5" hose, ie the inlet
better blower silencer
stronger recovery tank
stronger clutch to handle 14-15in Hg
carry more water, an extra 50 at min
