We've had this pressure washer for about a month so far, and have thus far used it to wash two of our cars as well as portions of our siding. The power it produces is sufficient to remove 10 years of grime and moss from vinyl siding. The unit is small, has great onboard storage, and is extremely easy to move around. The built in power cord is pretty long, though you may need an extension cord to get to out buildings if those buildings don't have power. If you're not using a pressure washer year round, multiple times a week for numerous hours a day, going with this over an engine powered pressure washer makes sense.
The unit was easy to unpack and assemble. It is lightweight, powerful, and compact. I especially like the large lockable wheels, they make the unit stable and easy to maneuver.
