Q: Bill, is there an adapter to connect this hammerhead to my 2500psi unit, i see the connector is presure fit and my unit has the screw connector. I hope I explained that well enough.
Greg by Greg Peterson from Ohio on October 16, 2011
A: This surface cleaner does come with a quick connect fitting. In order for your threaded hose to be compatible, you will have to purchase adapter part # AL457.
Q: How well does this work on interlocking concrete pavers with sand in-between? There is moss growing in the joints and the pavers have mold growing. by Mark from New York on August 07, 2011
A: This surface cleaner would work great for that application. However, you will definitely have to use at least a 2600-3000psi machine or larger in order to get great results. Also, just be aware that more than likely some of the sand in between the joints will be blown out. As far as removing the mold off the pavers, you should be satisfied with the performance of this product. by Bill, Product Expert
Q: where do i put the grease into?.....no zerk fitting by John from Washington on July 28, 2011
A: If you recently purchased this product, you do not need to grease them. The newer versions of this item do use a zerk fitting that does not require grease. The older models will have a grease point around the rotating head assembly. If you do not see a grease point, then more than likely you have the newer version and it does not need to be greased by Bill, Product Expert
Q: Would it be safe to use a 4200 PSI pressure washer with this surface cleaner? Or would you recommended just turning down the pressure? by Jeff from Texas on March 30, 2011
A: Yes you can definitely use a 4200 psi pressure washer with this surface cleaner. You might want to dial down the pressure just a little bit but it really isnt needed. However, the only way you can push the full 4200 psi is by using a zero degree spray tip. Normal operating pressure of a 4200 psi model is going to be 4000 psi. The additional 200 psi is only obtained by constricting the water through the hose and spray tip that I mentioned. by Bill, Product Expert
Q: Have a Karcher residential G3050 gas presure washer. Will the GP Hammerhead Surface Gleaner work with this machine? Would purchase include necessary hoses/wands/etc. to couple the G3050 or are these a separate purchase? If separate, what is required?
Thanks Tom J by Tom from Washington on March 28, 2011
A: Yes this surface cleaner would definitely work with your model pressure washer. This surface cleaner comes with all components shown in the picture and would connect directly up to your existing pressure washer hose. In your situation, since your existing hose should be threaded, you would also need to purchase an adapter model D10089.
Q: i have a 3gpm, 2500 psi pressure washer with a cat pump and honda motor. Will my pressure washer be powerful enough to use with the 18'' GP hammerhead? by Chez from Texas on March 25, 2011
A: Yes, you can absolutely use this surface cleaner with a 2500 psi pressure washer. The GP Hammerhead surface cleaners require a minimum of 1000 psi to operate and can be used with pressure washers up to 4000 psi. This surface cleaner can also be operated with any gpm rating up to 8 gpm's. by Bill, Product Expert

Bill's Recommendation
The Hammerhead Surface Cleaner is considered prosumer-grade. You can either consider it an extremely expensive consumer-grade surface cleaner. Or, it's a very inexpensive professional-grade unit.
That choice is up to you.
We love it because it's durable. The Hammerhead features a composite housing - not some cheap plastic cover. Plus, it includes a hearty handle. Simply snap your high pressure hose into the trigger gun on the handle.
The Hammerhead actually hovers over the surface. You need at least a prosumer-grade pressure washer for it to operate properly. It's not designed for the little power washer found at your neighborhood discount store.

Best choice
I have used the GP cleaner twice now and it works well and saves time.
This is the best choice for pressure washing a garage floor. Cleans the floor without the overspray all over the interior. Highly recommend.
I also used outside on dirty concrete. Works on indoor and outdoor apps.

Did a great job
Since I've never used a surface cleaner without wheels, I test drove it first on my concrete driveway. It worked very well.
I learned that you can't push this surface cleaner too fast or the back side will lift. A slow steady motion is all it takes, using my 2700psi, 3gpm pressure washer.
It did a great job on my driveway. Then on to the real test, 8000 feet of driveway with lots of moss and dirt on it. It did a great job on that old concrete driveway, and I was able to finish it in one day.
The only thing I'm concerned about is the longevity of the brush skirt.

Wish I had it years ago
I wish I had discovered this surface cleaner years ago.
Very consistent and powerful cleaning, no lines, and much faster, especially on heavily soiled surfaces, than a standard wand!

I am blown away
I am extremely impressed with this product. What used to take me hours now takes much less. I was shocked when I saw the results.
I would recommend this to anyone.

Worth it
The Hammerhead surface cleaner is wonderful.
I was using the wand to do driveways and sidewalks. It was taking me over an hour. With the Hammerhead, I cut my time in half.
Takes up a little space when storing, but worth it. Very easy to operate

My back loves it
My wife and I have to pressure wash our driveway and pool deck every year due to algae buildup that occurs over the winter in this part of the south.
Until recently it has always taken at least 2 days to get them both done. This year, after struggling through a long day pressure washing the deck with just a wand, I finally bought the General Pump 20 rotary washer to do the driveway.
With the rotary washer I was able to do the whole driveway in less than 2 hours, including rinsing everything off and putting everything away.
And, the best part is that I didn't end up with sore muscles like I used to! This is a very effective product.
Note that the rotary washer came unassembled and there were no assembly instructions in the box. However, there was a parts list with an exploded view of the unit that gave enough clues that I was able to figure it out.
I liked that the unit came with a quick-connect fitting, which allows me to quickly switch between the rotary washer and the wand.
I wish I'd bought this years ago!

Just used my Hammerhead surface cleaner for the first time, and it has lived up to the description given on your web site.
Did my 1600 sq. ft concrete yard area in less than half the time it used to take me, and no zebra stripping. Love it- so far a good investment.

Cleaned well, got done quick.
Worked very well- cleaned cement driveway and wood deck in much shorter time.

A lot less time and a lot less water
Used the surface cleaner at my home and on my parent's very large driveway. It took a lot less time and a lot less water.
So far I'm very happy with the product. I did have to buy an adapter so it would work with my pressure washer.
Also, thanks for shipping it so quickly.

Old man & 8000Sqr. feet of driveway & pool deck
I am a 65 year old man in So. Ca.with kids gone but cannot afford to sell my house in this economy. Qualified people to clean my large driveway & pool deck are hard to come by. Both the driveway & pool deck are color coated.My solution to this problem is as follows:
Purchased a Briggs & Stratton Prosumer Pressure washer ModelPRO3400. Most parts are made in USA. Pump is made in Italy and is all brass and can be repaired, unlike cast aluminum pumps.
After break in period, pump oil can be changed and Mobile gear oil 7590 W Synthetic can be added and pump oil should never need to be changed again. Solid machine.
Wand cleaning 8000 sq. feet will not improve your golf game, so I purchased a GP Hammerhead Surface Cleaner DFSCP20. Works great in removing embedded dirt and no swirl marks.
I clean 1000 sq. feet at a time and hose off the dirt left behind. Two people working together could save a lot of time.
What pictures would you like?
PWD RESPONDS: Showing the unit at work, or a section of deck that shows before & after is always helpful. We can add the pictures to this review if you would like to send them.

Great Surface Cleaner
Works great, light weight. Used for two straight hours and no signs of wear or tear.
Like the fact there is a grease fitting on top.
I would recommend this product to anyone.

Wow- what a great investment!
i work at a truck stop and bought the Hammmerhead for our diesel bays.
I had my maintenance guys outside pressure washing with just a wand... they would come back inside covered in oil from the spray of the pressure washer.
I was driving home one day and I saw a professional pressure washing company cleaning a business.. and I saw the surface cleaner!!
Wow, what a great investment... The first time we used it the diesel bays looked almost new... we have been opened for almost 6 years!
We didn't even use any soap or de-greaser!! The Hammerhead did an amazing job in half the time, and no zebra stripes!!
I will be talking to our other stores- they have to purchase Hammerheads!

Keeps its Promises
First, don’t let the sizable shipping box alarm you. This surface cleaner is a breeze to assemble and take apart. It comes in just three pieces so you can even haul it in a car.
Second, I had lots of caked-on dirty sidewalks and a patio to clean around an office building. It worked magically with my DeWalt 3800psi 4 gpm, and the time saving estimates are accurate.
Finally, this manufacturer makes a quality product. Buy it and don't look back. You won’t be disappointed.

How To Pick the Perfect Surface Cleaner
Are you tired of seeing uneven "zebra stripes" left by your pressure washer on the garage floor or patio?
Surface cleaners are the answer. Small nozzles on a spinning arm produce a smooth, even cleaning path.
Choosing the right one is easy! Just click on the style that matches your pressure washer.
Consumer Electric pressure washers use bayonet connectors that twist and click to lock together.
Most Consumer Gas units can use the M22 connector on the Karcher T350. If your spray gun uses quick connectors then adding a high pressure quick connector adapter kit will do the trick.
The Prosumer models make either a terrific Consumer investment or an entry level Professional choice.
Professional surface cleaners are built to take daily use by either gas or electric commercial pressure washers.
Most are rated up to 4000psi and can accept hot water. They are engineered for light weight and portability.
The right Surface Cleaner will save you time, water, and effort. They produce a nice uniform finish without soaking your clothes or your wallet.
