I just now looked at the link. For small uses that looks fine. Mine is a commercial washer and probably more than yall are looking for. I know on mine it has adjustable nozzles for different pressure and surfaces. LINK
This is similar to mine but I honestly dont even remember the name brand of mine. I got out of the business a few years back and havent messed with them since. I was actually thinking about selling my setup last night, thats why I jumped on this thread.
