I was immediately impressed by the compact form factor. I am concerned about the 500 psi discrepancy between the advertised max capacity and rated output. In particular it's unclear if it is in fact compatible with accessories like the 15" surface cleaner if it's unable to hit the minimum pressure requirement specified on the accessory. Fingers crossed.
My only recommendation would be to "mark" the nozzles with a darker/better/larger marking, to identify the nozzles (they're somewhat difficult to read); either that, or specify (in the owner's manual) a color-coding of the nozzles. Other than that, all good!
I received the unit as a gift for Christmas. The Unit was well packed and easy to set up. Not a bunch of unnecessary packaging. It was assembled and ready for use in ten minutes. The spray stream is perfect for cleaning the mold off the house vinyl siding, (its intended use).
