The ad says it can be used right away, unlike other brands which require a lot of assembly. Not true. It requires just as much assembly as another brand I purchased fro Amazon, but the actual assembly was a bit more difficult. Having said that, once assembled, it is clearly a superior machine to my previous machine if only because the hose connects directly to the high pressure outlet with a proper fitting instead of being attached to a hose reel swivel mount (which failed on the third use on the previous machine.Having now tested the machine I can report that it is WAY better than the WestForce Electric Pressure Washer, 3000 PSI 1.85 GPM Power Washer, 1800 W High Power Cleaner that I replaced after it failed. The Commowner 3000 PSI Electric Pressure Washer cleans better, but most important, it does not have the integrated hose on hose reel with the weak elbow that failed on the WestForce after 3 uses. As a result I upgraded its rating to a 4. The WestForce was under warranty, but I got no response at all when I requested replacement parts under warranty.
