CUSTOMER REVIEWS

Rated 4.3 out of 5 by 331 reviewers.
Rated 5.0 out of 5.0 by Power to spare and easy to use When I looked for power washers I was thinking about getting one that would be "future proof" meaning I would have enough power to do ANY (normal) household job while it being nimble enough for my wife to use should she want to. I looked at many electric and gas powered pressure washers and ended up buying this one due to is having a Honda motor and the great power and throughput measurements. So far I have used the pressure washer for about 10 hours. I washed my pool deck, my driveway and my walkway. It starts very easily and has enough power to do any job that I can imagine. My wife enjoys using it, so much so when she washed off the pool deck this weekend she pulled the washer out to use it and got the job done very quickly. One warning is that this has a LOT of power and when coupled with the nozzle that has the most concentrated beam is powerful enough to do damage to concrete and other porous surfaces. I made a nice dent in my concrete where I started using it. Overall I am glad I spent the extra $100 and went for a gas driven powerhouse. Since it is on wheels it is actually easier to move around that some of the electric ones I have used that are not on wheels. While I would not want to try to move this power washer in the cab of my car, given the size and weight, this is not something I would be very likely to do anyway. April 28, 2015
Rated 5.0 out of 5.0 by Works Great! I ordered the Simpson MSH3125-S thru Home Depot online after doing much research and comparisons. The MSH3125-S was shipped directly to my house, all components were received and it was easy to assemble basically the handle. After reviewing the instructions and adding the oil provided by Simpson, the Honda engine started right up. I like the chose of nozzles and the pressure hose is flexible. I agree with other reviews that I will probably order a longer hose. Otherwise, this is a powerful machine that moves effortlessly due to the real tires and does an excellent job of cleaning surfaces. Glad I chose a Simpson. June 10, 2015
Rated 4.0 out of 5.0 by Performance: This unit performed as anticipated and as the many reviews read before ordering. I like its compactness with the option of reversing the handles to save on storage space. I also appreciated the thorough information and caution regarding the nationwide ongoing problem we have with ethanol. I have mowers, string trimmers, blowers, chain saws and must add treatments to prevent fuel related issues. However I was very disappointed to discover that the idle and full speed jets are permnate and not adjustable. Otherwise at this time I am pleased with the unit. June 8, 2015
Rated 5.0 out of 5.0 by Fantastic!!! I have used more than one 2700 psi washer over several years, but this Simpson 3100 psi was significantly stronger. It worked twice as fast as my older (I wore it out) washer. So much pressure, I had to hold on to the wand with both hands!!! It really did speed up my jobs. Well worth the price. It will help me make more money quicker with more client satisfaction because it does such a good cleaning job so quickly. I bought it because of the Honda GC 190 and it has not disappointed me.

Rated 4.0 out of 5.0 by good product I purchased power washer about two weeks ago and am pleased with the product so far. The box the product was shipped in was damaged but the washer was ok June 20, 2015
Rated 4.0 out of 5.0 by Nice power but? The motor and water pump are incredibly powerful for such a small power washer. I have to say the engineering is superb. My only reason for not giving it an extra star is that someone chose to put cheap fittings on the connection pieces to the actual pump. Be careful not to miss thread otherwise you will strip it completely. No wonder the valves are on a two to three week backorder. June 12, 2015
Rated 5.0 out of 5.0 by Great machine!! Selected this washer over the other big name brands. Very pleased!! June 18, 2015
