Q: I'm retiring soon from the military and am in the beginning stages of researching pressure washing as a small business. I would be more than happy to receive any tips you may have on the subject. Thank you for providing a solid breakdown on the equipment you sell on this website. How would you compare the DR pressure washer with the prosumer models listed here?
by (Mr.) Ashley Holt from Virginia on May 03, 2014

A: I am not sure of the DR brand you are referring to. However, the Generac Prosumer model is a great choice. It uses a High Quality AR Triplex Plunger Pump with adjustable pressure. The AR pump is one of the best in the industry today. I would highly recommend the Generac brand.

Pressure Washers Direct Recommended

Prosumer grade units are the bridge between Consumer and Professional units. This brawny group of pressure washers are meant for larger projects- farms, estates, and small businesses.

Generac is known for its quality power equipment and reliable, commercial grade engines. This model is made in the U.S. and is a very good quality pressure washer. We receive virtually no negative feedback on these machines, which is one of the main reasons the 6590 made our recommended listings.

Stepped Up
Stepped up to this more industrial type pump unit and glad I did. You will spend $200 more over consumer units but this is not just about the pump . The entire unit is better quality from the hoses and connections to the tires to the gauge of metal in the frame its well worth the extra money.

I go to it not wondering if it will start or work that day, only how much I wanna clean!

Love it and Pressure Washers Direct!
Pros: Easy To Use, Price, Exceeded Expectations, I'd Buy It Again

Good Machine But
Purchased in April. Couldn't believe how fast it arrived. Easy to put together. Finally am using it this weekend. Powerful machine but continually stops running on me like it's out of gas. Check the gas and starts right up but will quit again over and over.

Gas cap issues?? I don't know. I guess I will call Generac on Monday 6/30/14
Pros: High Quality, Easy To Use

I checked Generac's Service Locator for pressure washer repair locations in your area, and there are 5 within 10 miles of your zip code. If you need Warranty Service, I would suggest calling around to find out who has the shortest turn-around time:

Junk
Started seeing silver in the water the 2nd time I used it. Took it to get fixed. Used it once after that and the crank case fills with water when its running and fills with gas when not in use. Now its leaking gas from the bowl and wont start. Its had more wrench time than run time.

Need A Better Gas Cap
I have used my new 3100 pressure washer 3 or 4 times since new and it is very powerful and very well built.

The problem I am having is the gas cap is not venting properly and in order to run the unit more than about 20 minutes, you have to unscrew or completely remove the cap... not good.

A very good pressure washer reduced to junk because of improper fuel tank venting; would not buy again.
Pros: Durable, Features, High Quality
Cons: Unreliable

Heavy Duty Unit
This model is very heavy duty from the frame, engine, and pump, to the hose and gun.

For its first use I ran it for around 3 hours to clean the upstairs back of my house and the underneath of my deck from the patio below. Things were very dirty from 2-3 years of no washing. We live in a wooded area with mud wasps, bee hives, birds nests, spider webs, and caked on dirt on the window casings. The pressure treated wood was all gray.

Window casings, bricks, concrete floor, and the pressure... more

Engine Quits
Ditto review from Sam in New Baltimore MI. Great unit when running, but quit 3 times first day I used it. Called Generac and was told by cust service they never heard of this. Had them go into your reviews to validate issue. Mine is in shop now. They couldn't (?) transfer me to anyone in tech support or warranty admin, said only a dealer can do that, (?) Right now I wish I hadn't bought it. We'll see what happens.
Pros: Features
Cons: Unreliable, Engine Quits
Mike, the Pressure Washer Expert
Product Expert
Richard,
I'm sorry to hear you're having a problem keeping the engine running- I hope you were able to solve the problem the way Sam did by unscrewing the cap enough to let the vapors out?

Generac Tech Support number is 888-436-3722, toll free and accessible to anyone. If you have a problem getting Factory Warranty Service, wherever you bought the unit can ask their sales rep at Generac to step in; they would be the ones to help sort things out with warranty admin.

I'm sorry Generac's customer service rep wasn't aware of the gas cap issue - they are a really large company handling a wide range of power tools, and the information may not have worked all the way through the food chain yet.

Very Pleased
I have owned several consumer type pressure washers and have been disappointed multiple times. Though I have limited time so far using the Generac, it seems to far superior in every respect.

I was very surprised / impressed with how quickly it arrived. I was fully expecting to wait at least a week. As I recall, I ordered on Tues and it arrived by Friday

So far, I could not be more satisfied.
Pros: I'd Buy It Again, Features, High Quality, Fast

Generac May Have An Engine Problem
I first noticed in the reviews prior to my purchase that some customers were having trouble with the Generac brand engine stalling on them. I thought every product has its quirks and a couple of lemons out of the thousands they distribute isn't out of the ordinary. However, Mine too is stalling with plenty of fuel in the tank. After a stall, I would check the fuel (and oil), then restart and it would run fine for another 10-15 min. and do it all over again.

Then I thought about the reviews... more

Sam,
I'm glad you found the information about the gas cap- and I apologize for the inconvenience. I'd suggest giving the folks at Generac a call, toll free, at 888-436-3722 to report the problem; that way you'll be on the list if they issue replacement gas caps.

Please be sure to have the serial number of your unit handy when you call Generac; they will ask for it to keep track of the issue.

Unreliabe?
Evey year I borrow or rent a Pressure Washer to use around my home (siding, vehicles,lawnmowers etc) and decided it was time to buy. I found Pessure Washers Direct in a search and ordered The Generac Prosumer 3100. It arrived within days of ordering it so thats good my plans were to take several days of my vacation and use my new purchase to do all my pressure washing needs.

On my first day and the third start up, water came gushing out around the handle hose connection, an obvious defect.... more

Washer arrived last Tuesday- Fed Ex, no problem. Unpacked Last Wednesday, all went great with set up of washer. Ran for about one hour and stopped. OK, take a break. Started up ran for about 5 min, stopped again. Did this three more times. Hummm, must be a problem, right?

Called Generac, first call lady gave me wrong number-not in service, called second time, got correct number, called again box was filled . Had an address. Last Thursday went to place of business, it was open, talked with... more

Great Pressure Washer
Used it to clean front porch and dog kennels, and it worked great. I just think it needs a bigger gas tank.
