Rated 4.5 out of 5 by 44 reviewers.
Rated 5.0 out of 5.0 by Rock Solid Perfect The CAT 3800 PSI 3.5GPM model is without a doubt the most well engineered pressure washer on the market. I have used pressure washer that had more PSI and GPM but CAT found the perfect number combination. More than enough power and water flow to clean EVERYTHING. Easy assembly, solid construction, and when I say solid, I mean everything; real rubber wheels, hose, spray tips, wand. 1st pull starts everytime. Does not 'walk' as some units do. CAT pump with Yamaha engine best combo you can get. The only caveat emptor is that this is a pro unit, not for everyone as this thing kicks, and you do need a little muscle to use it. April 30, 2011
Rated 5.0 out of 5.0 by I don't think you could do better than this pressure washer I am in the carpet cleaning business and a CAT pump is what is used on 20,000. carpet cleaning machines they have the best reputation in the industry. You can't go wrong with that pump and a Yamaha engine. The machine is amazing and works great. I have used it 4-5 times in the last month, it starts right up and the sound of that motor is quiet yet has a low rumble like a harley. It actually turns heads when the neighbors walk by. The feature of the motor only throttling up when you press the trigger also sets it apart from the rest and saves wear and tear on all the moving parts of the machine. It is heavy and would take 2 people to put it in a vehicle. March 25, 2012
Rated 5.0 out of 5.0 by amen fl i bought this pressure washer about a month ago-- i made sure it was full of oil then filled it with gas , connected the water lines, then held the trigger down to remove all the air from the lines and pump-- the yamaha engine cranked on the first pull, this engine is very easy to start and really puts out the power--i read all the reviews before i bought this pressure washer and was satisfied it would do a good job for me also, but was concerned about the cranking problem which proved to be no problem at all for me, if you are looking for a very good machine that should last a long time then this is the machine for you -- i highly recommend this one August 19, 2011
Rated 5.0 out of 5.0 by Awesome Machine Oh man I love this Idle Down Technology this saves on the wear and tear on the machine this Pressure washer is worth the buy, setup was a breeze also this Bad Boy has a lot of Power, don’t hesitate buy this machine if you need a powerful Pressure Washer.I researched the pump and the motor, Cat pump has been around for more than 20 years and Yamaha has also been around for quite a while good combo.

Rated 5.0 out of 5.0 by OUTSTANDING VALUE, EXCELLENT QUALITY I did my shopping for pressure washers this spring; and this unit turned out to be a great purchase. Previously bought a R**g*d 3000 psi but it only lasted 5 hrs until the seals blew. Tool it back to Home Depot and they gladly returned my money. It was a good move to spend a little more money to get this one. This unit ROCKS. Definitely professional grade. Have cleaned my driveway, house, truck and boat with this monster. Be careful not to strip paint; because this unit is capable of it. Packs a kick but I like how the pump scales up the pressure to full blast when you press the trigger..instead of the blunt kick you get when you press the trigger on some other models. This unit also comes with Lifetime Seal can get replacement seals once a year after you register. Get this water blaster. You will not be disappointed. .. March 4, 2012
Rated 5.0 out of 5.0 by This product really works great The very first day I received this power washer, I used it over 12 hrs straight. I worked great. I used it on concret to get stains and to clean the driveway. The concret looks brand new again. Other reviews says its hard to start. I never had a problem with this issue. I just had to make sure to pull the trigger on the wand to releave the pressure and you can pull start it much easier. Otherwise it is very hard to start. July 23, 2011
Rated 5.0 out of 5.0 by Two thumbs UP! this unit was easy to assemble (mount wheels and a few small parts) and operate. It started on the fourth pull and ran beautifully. I did not have any problems restarting the engine hot or cold. the quality of construction and power is on par with commercial units I've used. I'm very happy with my purchase and would recommend this washer. September 18, 2011
Rated 5.0 out of 5.0 by Great Pressure Washer!! This thing has plenty of power, starts great, and will pretty much do anything you need it to do. It even makes it more satisfying that I purchased this unit two days before they raised the price to $999 (I paid 799). To the person that complains about having to choke this unit during start up, get used to it. It is called CARB emissions. They are making these engines as efficient as possible. You are always going to find that late model engines will require choking to draw the gas due to the elimination of unburnt HC emissions. May 6, 2012
