I'm curious jon, what is a home washer ?
I'm wondering if a say $400-$500 washer typically falls in this class ?
I call a home washer one that is Direct drive, 6.5HP or less Gas engine ,sold at Walmart, Lowes, Home Depot, Nothing worng with them, I have a Troybilt that I got at lowes a few years ago and it is handy, And most of these Pressure washers the Pump is only good for about 100hrs, That is usually what they are rated for,
But a Belt Driven Washer, Either on a Skid with Wheels, Permanent Mounted, or Trailer Mounted, There is a Big difference, Your cleaning power comes from GPM, The more water you can wash the contaminants from the surface with the better you will clean
For example a 5.0GPM @2,000psi Washer will outclean a 3.0GPM 3,000psi, I am talking from my real world experience using washers to clean trucks before I work on them,
