Karcher pressure steam washer.  This unit can run from 450-2000 psi with the turn of a knob and the water temp can be adjusted anywhere from hydrant temperature to 310 degrees for steam cleaning.  It uses 4gpm of water.  It runs on 220 volt for the pump and uses diesel for heating the water.  It has 2 soap solution containers built in that works as well or better than the carwashes in town (not the cheesy suction hose that never works).  It also uses a descaler additive called RM110 that kind of acts like a watersoftner and can be changed depending on your water hardness..  Unit is in perfect working order and runs as good as new.  Im only selling it  to upgrade to a little larger unit.  Price as it shows in the pictures is $4100 with the hose reel and 100 foot steam rated hose.  Without the reel and a 50 foot hose instead of the 100 foot hose it is $3600.  For more info please call 785-294-0589.   Thanks for checking my ad.
