MSH3224 is rated 4.5882 out of 5 by 17.
Rated 5 out of 5 by from Great pump for the money, lots of pressure! I have not had the pump all that long but long enough to run 5 gal of fuel through it and has performed flawlessly. Cleans cement drives, walks and foundations with little effort and is amazing on decking. Carful with decking as the wrong tip will eat it up in hurry but a bit of testing will have you with the right tip. Easy starting every time and the only complaint comes from my wife who says the pressure makes her arm sore after an hour….

Rated 4 out of 5 by from so far so good, seems to be a strong washer. does what it says it should do! but, is somewhat hard to restart after refilling up with gas after running it awhile, had to wait a few minutes and relieve water pressure from gun a few times then it started, so a few minutes of cool down time after running it, and adding gas should do the trick. today was first day running it, hope it keeps running strong,will up date later.

Rated 5 out of 5 by from Love this power washer! The Honda engine is what sold me on this washer and I haven't regretted my purchase. I have used the washer 3 times now and it is very easy to start, move around and use. I'm not having the issue with vibration causing the unit to move around, it stays put wherever I put it. I have recommended this washer to 2 other friends who will probably end up purchasing one.

Rated 4 out of 5 by from Presure Washer I like the machine does a great job only thing I do not like is it will dance all over the place. If not paying attention and it goes off the driveway, and tip over.

Rated 5 out of 5 by from Love the Unit Purchased a 2800PSI unit and was never happy with the results. Took way too long to complete home tasking. When I lost the pump, I decided to purchase a new PWasher and found the Simpson unit with the honda engine. Have had it for a couple of months and love the responsiveness and power of this unit for my home. I would not purchase anything other than at 3200 or higher unit for home use.

Rated 5 out of 5 by from great machine I have only used it twice. But I am very impressed. I've got 2000 square feet of deck that used to take all day. I had it done in 3 hours. Definitely worth a little extra money. my old machine was 2600 psi. This one 3200. Love it.
