Love This Pressure Washer!
Very rugged, plenty of power for decks, porches and siding, and anything left outside like patio furniture etc. The water inlet fitting is fine...the fitting to machine threads and collar are metal and the fitting to hose threads are metal. The only thing that's plastic on it is the hose inlet collar which allows for a good grip to tighten the hose!

Great product for an electric power washer
This power washer performed as described. I like the ability to lower the pressure for different types of surfaces. Easy to change nozzles

Great pressure washer
Does its job extremely well. Easy to setup, use and put away. The variety of tips/spray pattern are beneficial. The electrical cord on board storage is like most vacuum cleaners, but a bit more heavy duty. The length of the electrical cord is generous. There are only to picky things (recall that I did give 5 stars) that I would have designed differently myself. First, the wand holder is a bit weak and flimsy. The wand can slip out easily. The other is the pressure hose on board storage; it really doesn't work well. It is easy enough to manage these two picky points for me. All around great product. Now all I need to do it let time pass and see if it holds up for years to come...

exactly what I (and relatives) needed
I no longer have the strength to pull start anything. This is perfect for me. I use it for all the jobs I did with gasoline units when younger. And when my sisters basement was recently flooded, using a no carbon monoxide gas driven unit was perfect for family too.
