Rated 5 out of 5 by All -in - one Best pressure washer I've ever owned ( 5 previous ). It does all I need around my home and beach house. December 16, 2014
Rated 5 out of 5 by Top Notch I bought mine through a TV sales program, did everything they said it would. It is a great machine. December 16, 2014
Rated 4 out of 5 by cant go wrong with adjustable psi on the One Wash I bought this pressure washer b/c I wanted the flexibility to adjust the pressure depending on the job. Ive only used it once to power wash my paver patio (to clean out some areas of polysand) in order to apply new polysand. The One Wash did the job and Im pleased with the purchase November 24, 2014
Rated 5 out of 5 by Alot of bang for the buck I bought this as a store display model. I was pleasently surprised when I used it for the first time. It started up with the second pull and has plenty of power for blasting 3 years worth of mildew off my home and deck. I like the adjustable pressure feature, something most other brands do not have.

Rated 4 out of 5 by Started on 2nd pull right out of the box This is a very good product and it works well. Pros: Overall, I think this is a solid pressure washer and I'm pleased with the purchase. Love the adjustable PSI. Very little setup needed and it started up right away. I like that it is not as loud as other power washers. The hose is long and the connections are easy and tight with no leaking. Cons: t's probably just a sign of the times but I think a bit too much plastic for the price. It would be nice if the handle were taller for more leverage. It's too short (I'm 5' 11". I also think the handle could be more sturdy. The gas tank cap is directly on top and makes is more difficult for today's gas cans. You'll most likely need a good funnel like I did to fill it without spilling all over the motor. Owners manual does a very poor job of explaining how to use the soap tank. November 1, 2014
