    • Great machine
Style: CRX420
First one came damaged and they shipped another one right out. I recommend Welding gloves or something very thick to protect you from the heat. With heat this thing has no problem stripping paint off a car to bare metal. Starts easy runs great

    • This thing is a BEAST!
Style: CRX420
The Simpson KB65132 is a beast of a pressure washer. Any oil spills, auto part, or concrete doesn't stand a chance against the 200F water this produces. This isn't a small machine nor is it cheap but you get what you pay for and this thing is worth every penny.

    • Don't buy this
Style: Honda GX390
When it arrived it was missing tips wand oil owners manual chemical tube and it doesn't work after fixing. So this machine doesn't come with battery so I put one on it so now it doesn't charge so when you start the engine it kills the battery so they give me $500 dollars back on missing parts. So I bought what I need to get started and this is not my first steam pressure washer. This machine has been a nightmare I would not buy this machine. So now I am going to have to look at the voltage regulator see why it's not charging and it said it was ship without oil and it had oil in the motor I think this machine was used so if you don't have enough power going to this machine the burner not going to work because it has a igniter that lights the fuel to burn . Also it's made in China I watch it's shipped from China. So they told take to place get fix and they say not under warranty go figure rip off 5000 dollars down the drain ... show more

Style: Electric 120V
Honda motor should be good. Easy to move. Holster for wand is not designed properly. Does not fit where directed to install. It over laps the dash board and the bolt is too short. Relocate with longer bolt or skip it all together. No instructions on how to use what I pressume is soap hose. Cannot wait to blast my patios. ... show more

    • The Difference Between Hot and Cold
Style: Electric 120V
Love this product for removing grease and oil from my equipment. The ease of cleaning with HOT is like night and day. This machine is well made, I've had no problems at all. I also like the Simpson company. I had a question from the owner's manual and the General Sales Manager took the time to answer my question, right away, and he knows his onions. I am completely satisfied and glad I purchased this little Simpson hot washer. ... show more
