Pressure washers are a big business for us. I was really taken aback when our pressure washer expert called me to the back to look at this gem. This hot water washer serves two washing wands that can clean with 3,000 psi at 4 gallons per minute. That's amazing performance. The water tanks are there for a couple reasons. You'd have to have pretty good water delivery to keep up with the pump. Having the tanks evens that out. The other thing is of course is that the unit is portable and you can haul it to where you have the work. We've just sold two of these out to the oil patch. I wouldn't be surprised if they don't become a big business for us.
