    1. Great Unit and at Great Price

      I am so satisfied with this purchase. Works great and does an outstanding job on all surfaces. Cleaned a brick sandstone planter WOW! Looks so good.... I am very happy with my selection of this Simpson model and National Generators thanks for the great service on this purchase! on 13th May 2018

    2. power washer extreme

      Easy set up and easy to use quick start powerful I washed the house already. The wand was damaged upon arrival I made a call and and new one should be on the way. on 22nd Feb 2018

    3. Very Well Pleased

      Started on the first pull and did a really good job on a very dirty driveway. I highly recommend this machine on 16th Aug 2016

    4. Great, Reliable Machine!

      I found this pressure washer to have more then enough power and it is easy to use. If you follow the proper procedure each time to start it up, it works fine. Be sure to add some fuel stabilizer unless you will change the fuel each week. The stabilizer keeps the gasoline viable with no problems. This engine has 2 oil fills because it is used on various machines and some have access on different sides. You can fill the oil on either side but changing oil should probably be done on the side with the drain hole on the deck plate, look for it. Adding oil is easier with a tapered end funnel. To start it follow the instructions. Be sure to turn on the fuel by moving the fuel switch to on, close the choke, move the slow fast lever to fast (Rabbit) then connect your hose which is turned on full. Remember to pull the trigger on the pressure hose to release pressure otherwise you will not be able to pull the cord.

      The handle is a little short so be prepared to stoop to move the unit. You may also have to put air in the tires as I did. The unit ships with the handle assembled backwards and the diagram isn't very clear. Remove the handle and reverse it to bolt it on to the lower portion of the unit. It would be useful to have a 3-5" extension on the handle to make it easier to move the unit around. It does vibrate when running so be prepared to chock the wheels or sit it on the grass so it doesn't move as easily. The rubber feet on the bottom came off so I added a split washer to the screws so they will not loosen again. Overall, I am very pleased with this pressure washer. I have had it about a week and used it 3-4 times during that period with a surface washer attachment a several nozzles. The wand that is supplied with the unit is a little short and needs to be replaced with a longer one for use with the surface cleaner attachment. Apparently the nozzle holder has been upgraded since it is now rubber so the nozzles no longer vibrate out as has been reported. Very pleased with its service so far and delivery was right on time. Thanks.

    8. Great Machine!

      Awesome Machine. Glad I did my homework. Best deal out there for a Triplex pump. Engine fired first pull, you absolutely can't go wrong with this machine. Couldn't be happier with my purchase. on 26th Feb 2016
