NorthStar 4200psi @ 3.5gal mobile washer with a Honda gasoline engine. I purchased the unit new last fall for $1650.00 + tax and shipping, but realized it was too robust for home use.  I'm willing to sell it at a loss to the first person with $700.00 cash. To me, it seems to be more of a commercial unit to clean trucks or construction equipment.  It has never been used and includes all documentation.  Very nice unit with aluminum frame and excellent wheels.
