Rated 4.3 out of 5 by 225 reviewers.
Rated 4 out of 5 by Solid machine Excellent product. No issue with gas tank size or exhaust location. Would like to see a feature allowing various Pressure settings, otherwise I'd give it 5 stars. Hose storage on handle is very awkward, but that's been my experience with all pressure washers. Someday someone will invent a better mousetrap for that. July 29, 2014
Rated 4 out of 5 by I love this machine! Awesome! Lots of power! Not heavy, easy to pull around. Wish it had a bigger gas tank. June 3, 2014
Rated 4 out of 5 by So Far So Good Cleaned my backyard brick pavers for the first time in about 13 years. Used the green nozzle and it took a layer of moss/mold right off w/o damaging the pavers. I like the fact it has five different nozzles that are color coded so you can use the proper pressure for the job. Takes me several pulls to start when it's cold - not a problem, but not what Honda advertises. Will move around when running, depending on the surface, so pay attention. I'd also recommend a hose upgrade. The one that comes with it is short, kinks, and is not very convenient if you're covering a fairly large area. Overall a very good product and well worth the money.

Rated 5 out of 5 by best bang for your buck I have used it on a apartment complex washing the siding, It worked all day without a minute of trouble. May 13, 2014
Rated 5 out of 5 by Perfect I'm a general contractor and expect to use this item moderately (occasional houses, decks, drives). I took that into account when determining how much machine I needed for what I need to do or expect to do and how much I was willing to spend for it. As always, I researched like crazy and ended up with this model. It showed up ahead of schedule. It sat for a few weeks in the box before I had the chance to attend to it and use it. Easy assemblage out of the box and well packed. I took it out, put the handle on, gassed and oiled it up with the provided oil, hit the :on" switch, pulled choke, tugged the pull cord a couple times to take up and slack and get some fluids moving and gave it a nice hard pull and it worked on the first try. I used it for two days in a row to wash a two story house, double garage, porch, walk and 300 ft drive way. Not one issue. It purred like a kitten the whole time. For the price, it is my belief you're getting a great engine with above average accessories. Ya, I wish the hose was longer (25' provided) and it had a on board detergent system instead of the siphon tube but I also didn't pay $500+. And I can buy better accessories as I go. The spray gun I would say is well built and about what I expected. I'll get another one eventually. The engine/pump is the important part. I ended up buying a 50' extra hose , a 18' telescopic gun/sprayer from Blue Hawk, some quick release fittings for both guns and hoses. I also found it useful to attach a brass 1/4 turn shutoff (quick release) at the intake. If you're on the fence between two like models i'd push you this way ;) June 23, 2014
