Q: Please recommend a good telescoping wand and gutter attachment for the 6602. I'm not finding definitive info on fitting compatability. 3/8 or 1/4. Need 18-20 ft wand. Thanks

by Andre Godefroy from Washington on June 26, 2016

A: The BE 18-Foot Fiberglass Telescoping Wand would be a good choice since it comes with an M22 adapter that will let it connect to the 6602 hose.

The telescoping wand has a 1/4" quick connect tip, and will work well with BE's Quick Connect Gutter Cleaner.

Please be aware that any telescoping wand will flex when water pressure is applied- they take good footing and a strong back to use comfortably. I'd also suggest using BE's Wand Support Belt to help control the telescoping wand.

Q: I am looking into the 6602. I plan to use for general cleaning and am looking into getting the jetter hose attachment to clean my drainage tile(live in country dont want to pay $100 to clean anymore leaves) will this work fine for me.
by Harvey Hooten from Indiana on June 03, 2015

A: Yes this would be a good choice for you.

Also, I would recommend a Jetter conversion kit for your Jetting needs. I would recommend model 43.5002. I have attached a link for you to view that item.

Q: mike,

does the generac one wash 3100 have idle down?? I had a kohler pressure washer before and when you apply the trigger the rpms would ramp up. Is this idle down??? Also is a triplex pump worth the price if you use your pressure washer once a week for couple of hours..

by Patrick from Indiana on May 17, 2015

A: The unit comes with a throttle control. I've included the owners manual. The unit is in the consumer category and a few hours or less is week is recommended. If your looking for more hours the 6590 would be your next step up.

Q: Does this unit idle down when not washing?
Is the reason it only has three nozzle tips is because it also has adjustable pressure?
First time buyer trying to decide.
Thanks

by Tim Blaney from Arizona on May 16, 2015

A: The unit comes with throttle control to help the first time user set washing adjustments so there is less nozzles. If you want to move up to it's sister the 6598 let's you set the pressure with all the nozzles.

Q: Hi Mike, thanks for reading my question.
I am in a dilemma.
I am interested in purchasing this Generac pressure washer 6602 One Wash (3100 PSI) This has pressure control.
I also like the Karcher G 2800 FH, 2600 XH Karcher, Generac 6595-0, Generac 6598
I chose these for their performance and similar cost.
I'll use it is to clean concrete floors, walls coated (no damage) to clean mold. Once a day for 1 hour and a half.

Lately I've read bad cometary of Karcher machines. My neighbor told me that the pressure whasher buy Karcher G 2600 VH and tube many problems with it.
I have read very good reviews of Generac brand.
Interested durability. I take great care of my equipment and I have lasted many years, and now want a wahser pressure also durable.

Which of you two pressure washer do you recommend?
Thanks for your time.

by Jaime Campo from Texas on October 27, 2014

A: None of these units would be able to handle daily usage. They are consumer items and would not handle what you are doing. I would recommend going with the Generac 6590. This unit has a triplex plunger pump on it, and can handle your usage. I have attached a link for you to view that item.

Generac 6590
by Brian, Product Expert
Q: Hello Mike,
I was in doubt between Generac 6602 and 6598 and ended up ordering 6602 (even you thought 6598 was a better choice) because one of my planned uses for the machine is car washing and I like the fact that you can regulate the pressure to avoid damaging the car. My other uses will be concrete cleaning (garage floor, walkway) and vinyl siding cleaning. Please tell me what additional attachments you would recommend for these tasks. Thanks

by Marc from New York on June 20, 2014

A: For concrete cleaning I like either a Turbo Nozzle or Surface Cleaner. These will aid in your cleaning as well as significantly decrease the times it takes to compete your task. For cleaning cars I love the Foamer Attachment. It will spray out detergent as thick as shaving cream!

Q: hi, looking at buying one what is better one generac 3100 model 6602 or the one 3100 dual tank cleaner

steve same price

by Steve from North Dakota on June 05, 2014

A: The One Wash 6602 is a great choice for households where several people will be using the unit for many different tasks- the controls are simple, and the adjustable pressure is very handy.

The 6598 is great for work around the house- the pressure isn't adjustable, so you'd need to use a wide spray nozzle to keep from blowing the lawn furniture across the yard instead of just turning down the pressure.

The dual detergent tanks of the 6598 are handy if you do a lot of car wash & wax, or house wash & pavement cleaning- you won't have to run back and forth to switch buckets. Just make sure you rinse them after every use so they don't clog up.

The 'better one' is the one that best suits your situation!

Just turn the dial to your job task and go. The Generac One-Wash is great for the first time user but even someone like myself I just click and go without adjusting pressure or worrying about applying the incorrect pressure.

The units includes an AR pump which is easy to maintain and a detergent tank so your not dragging a bottle around the house with you.

Generac One-Wash is the perfect gift to anyone considering pressure washing with a gas machine.

Hands Down Best I Have Ever Used For A Residential Power Washer
This thing is AWESOME! I use it with a spiral twisting tip and this thing take oil stains off the driveway, will actually splinter wood, I use mine at work to clean the streets after a certain area always floods and leaves 1-4" of hard mud and debris, starts on first pull every time, these other bad reviews I don't see it, I'm guessing OPERATOR ERROR! if you use right oil and right amt and prime the pump with water like your supposed to do they work great!

Product Expert
Jodee,
I'm sorry the unit got tipped over during shipping, getting oil in your air filter (and probably the spark plug), and I appreciate all the effort that went into cleaning it.

I checked your file, and I see where we've already ordered a replacement air filter for you. That should smooth out the engine performance and make it easier to use your pressure washer.

We appreciate your business, and apologize for any inconvenience.

Worked Great Right Out Of The Box
Little hesitant having read reviews on how product was received with defective or damaged parts. Received mine and while agree, the shipping box container should be more reinforced, everything was fine and after quick part installation the unit started right up and ran flawlessly for a 3 hour project.

Purchased the 15" circular brush attachment and what a must-have item. Made cleaning my son's driveway and sidewalks much easier and faster although as others have said, an extension to... more

Debra,
The idea behind One Wash is to make it as easy as possible to operate. Generac included the 3 most popular nozzles; with the adjustable pressure you can get the same results without adding the other 2.

The full Generac spray tip set is in stock if you're interested in them.

Great Adjustable Pressure Washer
Unlike some reviews, my pressure washer came undamaged, and all parts in place.

I have only used it a couple times, but the adjustable pressure comes in very useful. The pressure washer is very good on fuel, and is quieter than the other 2000 psi one I had. Engine runs very smooth.

For all wondering how much of the oil to add, put in 16 oz of the bottle that comes with it. After couple uses, you may have to add a 1 oz.

In all, great pressure washer for those who have many little... more

I tried my friend's out on a driveway and side walk with the turbo nozzle and it worked very well. I was spraying off dirt and algae.

So I went home and ordered one for my business.

Missing Parts When Delivered
Washer delivered & after carefully opening box and removing and double checking contents the spray nozzles were missing. I called Customer Service and parts were ordered, said it would take 7 to 10 business days. What??? It only took 4 business days to get the power washer from the day I ordered it which I was pleasantly surprised.... Ordered on 12/28/2015, delivered 01/04/2016 (3 day holiday weekend)...

One would think they would expedite missing parts for a new power washer.

Craig,
I apologize for the experience you are having. The quick delivery was because we had the units in stock. The missing parts had to be ordered straight from the manufacturer.

I want to apologize on behalf of Generac for not putting all of the parts in the box with the unit. Also, since we sold you the unit, I have no problem reimbursing you for the cost of the parts if you want to pick the spray tips up locally.

Please give me a call at 800-710-7499 and we can discuss the quickest way to get this issues resolved. Again, I apologize and look forward to hearing from you.

Still Waiting To Be Impressed...
I purchased my pressure washer on May 20th and received it in just a few days.

The only issue I have is that after following the directions step by step, taking my time to ensure I followed each one properly, I I I finally started my pressure washer and the pump lasted all of 3 minutes. Since that time I have dealt with Generac and their authorized maintenance dealers. It has been out for repair for the better part of three weeks due to a defective pump, and the only update I get is when I... more

Fun To Use
We are very pleased with our Generac 6602 power washer. Our first project was our deck. It has not been power washed for 2 years and is now bright and clean.

It was easy to assemble, easy to start, and actually fun to use.

Our only complaint is shipping FedEx. It was only 2 states away and was sent to other states but ours. And several days back and forth between 2 towns in N. C. Once it arrived in our state FedEx asked us to drive 1 hour one way to pick it up. After our phone call... more

I checked the tracking record for your order- it was definitely unusual. I've forwarded it to our Logistics department; they spoke with FedEX who pointed out that the Zip Code on your order was incorrect; you had entered a NC zip code- the first digit in the zip code you entered should have been a 1, not a 2.

We appreciate your business and apologize for the inconvenience!

Started In 3 Tries
When I received my Generac Pressure, I removed it from the box and set it up per instruction. I filled with fuel and supplied oil. I then started it up, 3 tries. And it was ready to go.

My main issue was that the shutoff switch didn't work. I had to choke it out to get it to stop .This is not good for the equipment right out of box. I have seen other complaint with the same issue.

I would think that your company would have this issue fixed by now with the complaints. It seems that... more

Donald,
Some Generac units have had this problem- we have let them know and they are working to remedy the situation.

Please give the folks at Generac a call, toll free, at 888-436-3722. If there isn't a simple fix you can do yourself (in some cases it has been just connecting a wire), they will direct you to a Factory Authorized Warranty Service location in your area.

Please have the serial number of your pressure washer handy when you call them- they will ask for it. If you also need a copy of your invoice, just click on My Account in the upper right corner of our website and follow the prompts to print one out.

If you do need to take it to be serviced, you may want ot see if there is more than one place in your area. Then call around to see which has the shortest turn-around time so you can be up and running as soon as possible.

We appreciate your business, and apologize for any inconvenience.
