Rated 5 out of 5 by from Great pressure washer First one I have owned however have used many others. Easy to hook up. Following the "book", priming the pump, one pull and it is up and running. While I have used higher pressure washers, the 2,500 psi is perfect for small to almost large jobs. I cleaned my single wide in just over 3 hours along with 2 vehicles. Value for the money for sure. Also this unit gets GREAT gas mileage. I have had to shut off the gas supply as I can't seem to run it out of gas. (Less than two tanks to clean the above mentioned single wide on two different days. )

Rated 4 out of 5 by from Great Product I can't give a 5 star rating simply because the auto soap does not work, have tried several different methods with no results, I use the black nozzle as required, making sure filter is not plugged, will not pick up soap. No help from trouble shooter in instructions , other than that item good machine.

Rated 5 out of 5 by from Easy setup and ready to go Considering the online reviews, price and looks of this washer, I purchased one. I was very happy that the assembly was a breeze. Everything was provided, no tools were needed and it didn't take more than 15 to 20 minutes to complete. When I looked at the pictures online I was a little concerned about the tires/wheels because it looked like it was going to be cheap plastic. I was happy when I realized the wheels were a hard durable plastic that roll easily and look like they will be fine for my needs. I have not been able to use it for my deck cleaning yet. While I do not have any concerns I am comforted by it's 2 year warranty.

Rated 5 out of 5 by from Great little washer After going through two electric power washers, decided electric versions are junk. Decided on this gas model after researching. Great washer, easy to set up and use. Using the soap during wash worked well. Will probably last me forever. Using it to clean vehicles, and house.
