I appreciate You help,

by JAIME SANCHEZ from Texas on August 07, 2016

You may also find this How To Start Or Expand Your Business article from our How-To Library helpful. Here you will also find How-To tips for specific cleaning projects.

Q: Does the Hammerhead surface cleaner include the 3/8" socket high pressure quick connector required to connect it with my pressure washer hose?

If not, are the threads on the surface cleaner male or female?

by Craig from Washington on July 10, 2016

A: General Pump tells us this comes with a 3/8" female quick connect socket- we show the picture in one of the orange boxes across the top of the Features section.

Q: Afternoon Mike,
Quick question? My Hammerhead 20' doesn't have a Zerk to add grease? Use it, love it, but concerned it's going to burn-up. Checked the top and bottom, no attachment? Bought it from you'll about 2 months ago. Did I get an old one or is there another way to lubricate it? Thanks

by JC Charles from Florida on June 28, 2016

A: Can you forward your model number or order number? We offer two one with a zerk and one without which does not offer a grease option.
by Brian, Product Expert
Q: I have purchased this model: ALH3228-S from you a few weeks ago. What would be the best surface cleaner for my machine? Alot of the reviews for the 16" cleaner say that a 3200 psi has a hard time running a surface cleaner rated from 3100-4000.
by Wes from Texas on June 27, 2016

A: The Simpson 15" Surface Cleaner rated to 3400 PSI was designed to work with your pressure washer; since your pressure is near the top of the rating you would get good performance from it.

Your pressure washer at 2.8 GPM doesn't deliver enough water volume to drive either of the 16" surface cleaners we sell. The Specs tabs show the BE unit needs at least 3.5 GPM to operate properly, and the Eagle unit needs 4 GPM minimum.
by Brian, Product Expert
Q: What type of grease do I use for the zerk fitting?
by Margaret Mulberry from Illinois on April 26, 2016

A: Grease the swivel with one or two grease gun pumps every 200 hours (or once about every 30 days of use). Use No. 2 general purpose waterproof lithium grease. For hotter water applications, use a quality high temperature grease.
by Brian, Product Expert
Q: What's the minimum PSI to operate this unit?
by Tom from Pennsylvania on January 07, 2016

A: The minimum PSI is 2000 but the most important thing is the GPM rating. The GPM needs to be AT LEAST 3.0 or the arm bar of the surface cleaner will not spin properly and cause streaking.
by Brian, Product Expert
Q: I have a small space I am trying to fit this under. What is the minimum clearance height I can use this with to get under and in my tight space?
by Margaret Mulberry from Illinois on September 16, 2015

A: You are able to get this in a space as low as 18" off the ground.

Pressure Washers Direct Recommended

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... more

Awesome Surface Cleaner!
I bought one of these with a kit in 2010. Last week mine fell off the trailer and was lost- by the time I turned around it was gone, so I went to my pressure washing supply house and bought a Whisper Wash that was twice as expensive as the Hammerhead.

When I hooked it up to use on a pool deck I stopped after about 3 minutes and called the supply house to say that the new, over-priced unit was not 1/2 as good as my 18-inch Hammerhead. So I ordered another awesome Hammerhead from Pressure... more

Hammerhead Cleaner
Started cleaning driveways and it worked great at first.

Now it leaves what resembles railroad tracks on both sides of the cleaning pattern. These "tracks" are cleaner than the center portion. I have tried going extremely slow and it gets worse.

Called tech help and bought new spray nozzles as recommended and not any better. Quit using this and began using a turbo nozzle and achieved much better results.

Good for cleaning wooden decks and outdoor carpet though.
Brian, the Pressure Washer Expert
Product Expert
Glenn,
You may want to follow up with the folks at GP while your surface cleaner is still in its warranty period. Their toll free number is (888) 474-5487.

If the new nozzles didn't solve the problem something else is going on; and the Hammerhead should be way more efficient at cleaning driveways than a turbo nozzle. Normally this is an an indication that one nozzle is plugged and can be unplugged usually by using a pin or paperclip to work the debris loose.
Jerry G


I checked our files and didn't see a listing for you, so please have your invoice handy when you call GP.

Great For Concrete
This does a great job on concrete, but not so good for pavers. Leaves streaks unless you go super slow.
Donald Recommends This General Pump Product
Brian, the Pressure Washer Expert
Product Expert
Donald,
Surface cleaners perform best on smooth surfaces like concrete. The varied textures in some pavers and heavily pebbled cement patios can be a challenge since the nozzles rotate on a flat plane.

You may have more even results if you first flush out the nooks and crannies with a regular nozzle, then finish with the surface cleaner.

Amazing Surface Cleaner
I paired it with the EB4040HC pressure washer,.. this will cut your cleaning time to 1/3. The going to the surface cleaner is a bit stiff and might take time to break in. In the mean time I set a weight on it so it lay flat while in use.

Works PERFECT!!!
Pros: Easy To Use, Light Weight, Exceeded Expectations, High Quality

Save Your Back!!!
For a number of years, we have purchased a "cheap" pressure washer at one of those "club" stores and used the wand to clean sidewalks in our baseball park. Talk about killing your back!!

This year we purchased a 4200 psi machine and this 20" surface cleaner. Does an awesome job in a fraction of the time. If you have the ability to do so, have one water hose going to the pressure washer and somebody with another hose right behind the surface cleaner rinsing the... more

Water Hub
This surface cleaner worked well when I first purchased the unit. I use it daily, year round. The problem that I have had is that the water hub wears out very fast causing a good bit of down time.

This brush coupled together with the Mosmatic swivel that I used to replace the original with has worked for the past three years with out problems. The original price of the unit coupled with the cost of the Mosmatic water hub brought the price up to around $600. So you have to look at the... more

Happy Homeowner
I was amazed at how fast I was able to clean my driveway, porch, sidewalks and patio. My wife followed behind with a hose to rinse. Had a lot of exposed aggregate concrete to clean. And it did a good job of cleaning.

It is a bit expensive but this thing paid for itself in its first use.

No problems assembling or using it. I used a 4200 PSI four gallon per minute power washer to power it.

Best Money I Ever Spent !!
Well cleaning my driveway for the past several years at 3 to 4 inches every stroke. It was just depressing when it came time to do it. It took all day to do my driveway and sidewalks.

With this new unit it takes me less than 2 hours- best money I ever spent !!!

Real Time Saver
I grew tired of cleaning my walks and driveway with just a turbo nozzle. That job seemed to take forever and it took a toll on me physically. I decided on purchasing this surface cleaner because it met all of my requirements and also had a zerk fitting to grease it.

It is a well made product and very easy to use. It cleans my concrete quickly with no zebra striping. This surface cleaner reduced my cleaning time by 80%. No more stiff neck and aching back!

"I was some what disappointed that my purchase was put on hold do to back order. However, I did receive my surface cleaner in the time frame I was given via email. At some point I spoke with a Pressure Washers Direct customer rep. and I found him to be very easy to work with. Overall a positive experience! I would do business with you again."
