Hi my name is Anthony and I reviewed the Simoniz 1900 psi electric pressure washer. The unit was very easy to assemble. I pulled it out of the box. I basically connected the hose to the back, connected the hose to the nozzle, screw it down, connected my exterior hose to the front of the unit and you're ready to go. So you've got a sprayer nozzle that easily comes apart. You also got a detergent nozzle. I use it to clean the front steps of my house, my diving board on my pool, my sidewalk, the siding of my house. It seems to have worked great for everything I have used it for so far. For an electric pressure washer I think I'd definitely recommend it for anyone. Again, it was very easy to use right out of the box. No issues with assembly.
