Product Description

Product Description

Power wash your deck, prep for painting, remove tough concrete stains and more with this powerful pressure washer from Generac. Long been known for their quality engines, this model is no exception, equipped with a powerful 212cc Generac OHV engine. Also included are five Quick-Click nozzle tips (0-degree Blast, 15-degree Strip, 25-degree Clean, 40-degree Wash, Soap), and a 35 foot hose. Generac's power washers are carefully engineered for longevity and ease of use, with well thought-out features not found on competitive models. Easy to maneuver, the welded frame is designed for durability, with a built-in step for easy starting and an integrated gun holster. The easily accessible high-performance axial cam pump provides maximum heat dissipation for extended life and the easy to pull trigger reduces fatigue. The pump is located well above the ground, eliminating the need to kneel down to make hose connections. Backed with a 3 year limited warranty. Founded in 1959, Generac has earned a reputation as the company home and business owners turn to when the power goes out. The first to engineer affordable home standby generators, along with the first engine developed specifically for the rigors of generator use, Generac now sells more home standby generators than all of our competitors combined. We have brought this same level of commitment and quality to our pressure washer products. Our customer research has led us to engineer our pressure washers from the ground up, to meet your specific demands. Generac manufactures the widest range of power products in the marketplace including portable, RV, residential, commercial and industrial generators. Generac also operates three large factories which employs thousands of workers in the American Midwest.

Long known for its portable generator design, Generac introduces its lineup of commercial-grade pressure washers, enabling you to power wash your deck, prep for painting, remove tough concrete stains, and more at home and on the job site. The Generac 5993 provides 3,100 PSI of power and 2.8 gallons per minute (GPM) for a cleaning power rating of 8400.

Generac 5993
The Generac 5993 power washer.

It's powered by a Generac overhead valve (OHV) horizontal-shaft engine, the largest available for its respective pressure rating. Generac OHV engines come standard with low-oil shutdown to protect and prolong the life of the engine. Both the engine and pump are perfectly balanced over the axle and wheels for almost effortless maneuverability, regardless of terrain. Generac pro models also offer durable, welded roll-cage style frames that protect both the engine and pump from damage.

It comes with an ergonomically designed professional-grade spray gun, which features a unique cushion grip that reduces fatigue by minimizing vibration. The innovative easy-to-pull spray trigger can be held with a minimum of effort, and the Quick-Click nozzle tips are easy to replace. Additionally, this pressure washer's gun comes with an adjustable side handle for additional comfort and control when cleaning up high, down low, or anywhere in between.

This power washer is backed by a three-year limited warranty.

Note for California residents: This model is not CARB-compliant. Units sold to California must be CARB-compliant.

What Is PSI and GPM?

Short for "pounds per square inch," PSI is a measure of the water pressure coming out of the power washer. A typical garden hose dispenses water at about 30-40 PSI, and a coin-operated car wash provides about 700 PSI. A power washer, by contrast, typically dispenses water at several thousand PSI. Another important factor in power washers is GPM, which stands for "gallons per minute" and describes how much water is flowing through the pressure washer.

Together, they provide your power washer's cleaning power. Multiply PSI (which gives you the power to lift dirt and grime) by GPM (which provides the necessary quantity of water to wash it away) to get the cleaning power rating. The higher the number, the greater the cleaning power.

Here are some application examples with how much cleaning power (PSI and GPM) you'll need to get the job done.

I bought this Generac 5993 power washer a couple of weeks ago. I like it but Generac appears to need some attention focused on their packaging and shipment of these units. The first one arrived in a box that looked like it had been shipped via Afghanistan and soaked in oil. Based on reviews here on Amazon I had a pretty good idea what had happened. I opened the top and sure enough the pump was dry. That was the pump oil coating the box and everything inside. So, I rejected that shipment and after some hesitation, I reordered.

Generac ships the engine dry with a bottle of oil to be added during setup. Why not do the same with the pump oil and avoid what appears to be a common source of costly returns and a perception of quality issues? The pump oil is user serviceable through a cap on top of the pump. But because I didn't want to deal with cleanup of everything inside the box and I'd have to go find 30 weight non-detergent oil which isn't all that common, back it went.

The second unit arrived without a problem in about four days and in fine shape. Total lost work time, one weekend. C'est la vie. Setup was pretty easy and took maybe 15 minutes. Remove box. Rotate handle into place and lock with retaining pin. Install the hose hanger with two allen screws and the supplied allen wrench. Fill the crankcase with the supplied engine oil. Check the oil level in the pump. Fill the gas tank. And insert the soap tube on it's brass nipple. Aside from that it was just a matter of inserting the 5 color coded spray tips in their color designated holders on the handle, assembling the spray wand and hanging the hose on the unit.

I have used this pressure washer for about 5 hours on two separate days since purchasing. I cleaned the front of the house (siding) and the front steps (concrete). I used the green nozzle and was surprised how good of a job it did, especially on the concrete. I next did the concrete driveway and it looks like a new concrete job. Machine is very easy to use. Just read the instructions so you know how to make it last.

Just receive my new pressure and was like a kid at Christmas time, and was disappointed like a kid with a broken toy. I called Generac only to be refered to several different dealers in the area. Because I bought from Amazon and not from them they will charge me to fix it. One dealer said he would not fix it and would be very leary of Amazon purchases.
I have proof of purchase and paid more than I planned but thought this would be a good choice, I as an end user should not have to be put out of anything to fix the problem. Generac is the governing agent for there service centers and should place customer service at the top of their list.
So here I am with a new broken unit that I need to pay to have a new unit fixed. Very disappointed

I purchased a Generac Pressure Washer last year from Amazon. The carrier brought it to my house and it was leaking oil all through the box, which was in shambles; thus, I refused it and was refunded. So this year, I thought, let's have another go at it...It was supposed to be delivered today but ABS Freight called me to let me know that their Virginia terminal notified him that the condition of the package made the item undeliverable. I am an avid Amazon Prime shopper and am thoroughly upset that this happened again.

Both items were Generac and were 2 different models, but I had the same results even though 2 different carriers were used.

This is the only time I have ever left feedback for an item that I did not use....but wanted to inform other consumers to be advised that you may not wish to purchase a Generac pressure washer if you need to utilize the item quickly. I really was excited about this purchase (as I have a lot of projects leftover from last year to do) and wanted my pressure washer purchase to work out this time. The price on Amazon was much lower than most other places but does me no good if I can't even get one that is not damaged in transit. Now, I wish I would have listened to the many other customers who purchased different Generac washers that were damaged upon delivery. I guess I will have to find one or a similar type locally.

Either Amazon or the manufacturer needs to do a much better job at packaging/bracing/securing these items. It is ridiculous that so many arrive to customers damaged, according to various Amazon reviews of Generac pressure washers. Why I love shopping on Amazon, they really dropped the ball on this one...or two!!!
