What was your old unit?After 15 years in business with a touchfree automatic wash, I am upgrading to a Washworld Razor. I love the build quality and reliability of this machine. I like the touchscreen and how it shows the status of the different components. The programmability is great, too. My old machine was limited to what I could offer, but not the razor; if I want a wash with 4 presoak passes and 3 HP rinse passes, I can do that.
