Q: Does this washer have a spot to put detergents already equipped on the unit?
by Arian Eslami from Virginia on October 17, 2014

A: This unit utilizes a siphon tube for detergents. There is no on board storage tank for the detergent. You will place the siphon tube in a bucket of detergent and when using the BLACK colored spray tip the detergent will pull from the bucket and be applied at low pressure. You will then just switch to another colored spray tip for rinsing.

Mis-leading Marketplace
Should not be marketed as Professional machine.Totally not built for Professional use. I own 2 of them and will never buy another.
Pros: Price
Cons: Low Quality, Pistol that Dewalt provides is potentially very dangerous.

Michael,
I'm sorry you're having issues with your pressure washers. These come with a 1 year Factory Warranty that covers defect in materials and workmanship- if you're still within the Warranty period you may want to give the folks at DeWalt a call at 1-877-362-4271. Please have the serial number(s) of the unit(s) handy when you call them.

These meet our specs for Professional units. They have a Honda GX commercial engine (consumer grade is GC); they have a triplex plunger pump (consumer grade is axial) that produces at least 3 GPM at 3000 PSI. This unit is rated by DeWalt as 4200 PSI and 4 GPM.

Miguel,
I checked our files and didn't see where you purchased your pressure washer from us, so I couldn't check your shipping record; but if your unit was tipped during shipping oil may have leaked out of the breather cap. You can check the oil levels of the motor and pump to see if that has happened. If that's the case, then filling the oil to the proper level will prep the unit for use.

If oil is actively dripping out of the pump or motor, you can call the folks at DeWalt Pressure Washer at 877-362-4271 or email them at http://www.dewaltpw.com for Factory Warranty assistance. Please be sure to have your invoice and the serial number of your pressure washer handy when you call them.

Great Power At A Great Price
I've used this pressure washer for a few months now and I have to say that it is the best one I've ever used. It has plenty of power to blast mildew and dirt off siding and walkways, as well as prepping decks for stain or paint. The frame is high quality and not cheap materials. It's a little on the heavy side for being a portable unit, so I have to use ramps on my pickup to get it into the truck by myself.

It takes some strength to pull the cable and I've found that if it doesnt start on... more

As Promised
We think we made the right decision buying the DeWalt pressure washer. It started up right out of the box with no difficulties whatsoever.

We used it to spray down our chicken houses and it did a great job. It was our first time making such a large purchase online but the washer arrived on time as promised with no damage on delivery.

We wouldn't hesitate to order from your company again!

Excellent Choice For A Busy Emergency Mgt. Office
Our office uses a pressure washer quite often....especially during the wet season in Florida.

This unit was a great selection for our agency- it has power, easy to crank, and easy to handle.

Highly recommended.

Great Washer
I paint for a living and have to pressure wash quite often. This washer is a great rig. I have run it for over 8 hrs for several days and there is no loss of power or trouble starting.

Very comparable to the more expensive rigs and has just as much power. Haven't had for to long but so far so good even for commercial use.
Pros: Durable, Price, Reliable, High Quality

Shark Nozzles
So far these nozzles are working very well. They are heavy, but heavy-duty in construction. The downside is that I don't believe that you can rebuild them like some other brands.

It is a a bit premature to rate them so soon without having more usage first. I will give them a higher rating for now because of the initial above expectation of their performance. I will adjust the rating if they let me as time progresses forward on their reliability.

Works Great
I purchased this pressure washer mainly to take off algae that forms on our pool deck. I worked great and took all algae off instantly.
My one issue is what other owners have mentioned. The hose connection is right under the connection for the pressure washer spray gun. You must be very careful when disconnecting the hose while the engine is still hot.

It is awkward if the hose is tight and in reaching in my hand coming from the other direction to remove the water hose I touched the engine... more
