Why the DISCREPANCY??? Which is correct???

Product description says this is a 3100 PSI 2.8 GPM Pressure Washer, but the product specifications state that the included hose is only rated to 3000 PSI!!! Is the Home Depot description correct that it's a 3100 PSI 2.8 GPM pressure washer that only has a hose rated for 3000 PSI? Or are other questions mentioning the PSI rating correct that this is ONLY a 3000 PSI Pressure Washer that Home Depot is listing as a 3100 PSI unit???
Asked by: itsaysso
Model #59932 comes with a 3/8 inch coolstream hose rated for 4000 PSI. The rated pressure for this model is 3100 PSI. Hope this helps.

3,100 PSI 2.8 GPM OHV Engine Triplex Pump Gas Powered Pressure Washer is rated 4.4 out of 5 by 94.
Rated 4 out of 5 by from Great....once I got it fixed This is a tale of before and after. When I got the unit it was easy to assemble and fired up on the third pull. Everything worked great for the first hour and then it just shut down like it tripped the low oil regulator. After 3 forty mile round trips to the repair shop we finally determined the gas cap was not breathing correctly creating a vacuum in the tank and prohibiting proper fuel delivery. Needless to say I was extremely frustrated and out about 10 hours of wasted time. Now that it is fixed it runs and cleans great. If it were not for the initial problems I would be extatic and highly recommend this unit. I've not seen in any other reviews on the web that this problem is systemic but it is still an indication of a design problem and QC failure. One final note. When I called the company they were very helpful and got me to a great repair shop (Goodsell in Kirkland, Wa). I was not charged anything for the three times it was in the shop which is expected but none-the-less appreciated.

Rated 4 out of 5 by from Good Product... a few things to know though... This is an excellent product and know that I am familiar with some of it's character traits life using it is much more enjoyable. These tips will make your purchase much more enjoyable right from the start: 1. The wheel vibration can create a very loud & annoying sound easily remedied by putting a bungee cord between the wheels & frame. I've not removed mine since I placed it there, problem solved. 2. Once you turn it off and go to restart it DON'T BE SURPRISED when you pull the starting handle and it suddenly seizes and won't pull again. It's caused by water pressure in the spray line. This is clearly explained in the manual but, in case you use w/o reading 1st always know this approach for enjoyable use>>> ALWAYS MOVE THE THROTTLE FROM FAST TO SLOW BEFORE ENGAGING THE KILL SWITCH TO "OFF" AND ALWAYS FOLLOW THIS BY PULLING THE SPRAY TRIGGER TO RELEASE THE WATER PRESSURE & REPEAT PRESSURE RELEASE BEFORE STARTING AGAIN. 3. If you plan to use this for most of the day for cleaning house, driveway, etc... either keep a full gas can close by or buy the next model size larger to have the larger gas tank. Once you keep all this in mind it is a powerful and dependable machine! I actually use the pressure dial quite often to TURN DOWN the available pressure when washing vehicles & home siding. Last tip, buy a surface cleaner attachment- it makes cleaning flat surfaces fast work with beautiful results!

Rated 5 out of 5 by from GREAT pressure washer - buy it. I looked at many washers and this one had everything I wanted. The gas tank is almost one gallon and I liked the solid tires as well. There were some complaints of hard starting when warm, I had NO problems there. I got it set up, adding oils in the engine and pump. Hooked the hose up and naturally let the water run through the system before starting. I pulled the chock, set the speed to high and with one pull and it fired right up. Plenty of pressure and ran great. I didn’t like the cheap bracket for the hose or the location of it so I made my own. I bought an 18 inch 5/16 threaded rod. I cut it in two 7 inch lengths and bent the last inch up at about 30 degrees. I drilled two holes in the bracket in back about 6 inches apart and using two nuts and washers on each rod. I now have a nice hose bracket that takes up no room and is not affected if I put the handle down. I let the company know of this idea so I’ll see if they give me some credit for it :o)

Rated 4 out of 5 by from exellent value After a very poor experience with a well known brand and doing extensive research on pressure washers I picked the Generac 3100 pro machine. It performs flawless in exess of its stated specs. The Generac customer service is excellent. A call is answered in minutes. When there were problems with my old machine Home Depot , where I had bought the PW , assisted me big time. After 4 attempts to repair the 1 year old PW they got me my purchase price from the Mfr back. For price and service go to Home Depot!

Rated 5 out of 5 by from Has met my expectations. So far, after 12 hours of use, I'm pleased with this unit's performance. It usually starts on the first pull when cold, but then restarts when warm require finessing the choke control. This is my first gas-powered pressure washer and it sure beats the old 1200 psi electric K...... I've used for the past 20 years. I just hope this unit lasts as long - the K...... still operates fine, just not powerful enough for the jobs I have. With a wand extension I can now clean a two story pool enclosure without having to shimmy up and down an 8 foot step ladder. The stainless steel 36 inch wand extension I purchased from HD did not give me enough reach, so I borrowed my neighbor's 60 inch aluminum extension, which worked great. Also, adding an additional 50 feet of high pressure hose allowed me to get where I needed without having to move the washer. A larger fuel tank and an onboard detergent dispenser would make this washer complete. The included wand with handle works great. The handle allows much better control and support of the wand. Also, using a 15 inch diameter floor cleaning attachment sold separately makes driveway, sidewalk and deck cleaning go much faster and with greater uniformity.

Rated 5 out of 5 by from Highly recommend this product on every level. Excellent features including pressure control valve and low oil shut down. Plenty of power. Solid and sturdy, but not so heavy that it can't be easily maneuvered. Very easy to use. Only negative is poor access to oil fill. Very inconvenient.
