Generac 6596 Gas Power Washer Review

A Gas Pressure Washer that Delivers Plenty of Power

If you have spent at least an hour researching pressure washers, you will already know they are categorized based on the power source they use, and electric or gas powered units are the most popular choice among buyers.

Now, I’m not going to tell you which are best because both options have their advantages. Electric pressure washers are much lighter, easier to maintain and run, and are generally more compact so they score more points in that respect. On the other hand, they are less powerful than their gas powered counterparts, and gas pressure washers also give you more freedom to move around since you don’t have to hook it up to a source of electricity.

One of the biggest names in the pressure washer industry is Generac. They offer plenty of models, so pretty much anyone can find a pressure washer to suit their needs. I’ve decided to review the Generac 6596 gas powered pressure washer which is designed for residential use as well as the older model, the Generac 6595 (since both of them are similar).

Features and Specifications

The main difference between the 6596 and the 6595 is power: With 2.5 GPM vs 2.3 GPM, the 6596 provides 2800 PSI of water pressure and the 6595 delivers 2500. They are pretty much the same in nearly all other aspects. 2.5 GPM is a staggering figure, so the 6596 gets bonus points for that.

Both models are equipped with a robust 196cc OHV motor so they have plenty of punch. The engine has a recoil starter which appears to be universally acclaimed by everyone who bought the unit, largely due to the fact it only requires a few pulls in order to start up.

Pump Design

The Generac’s pump features an axial cam design. The reason why an axial pump is built into this unit is to keep it affordable. You see triplex pumps have a longer life, but units that have them are incredibly expensive. Even though this gas pressure washer is a heavy duty piece of equipment, it is still made for non-commercial use. For your residential cleaning needs, a unit that has an axial cam pump should do the job just fine.


The 6596 weighs 61lbs which is not a lot for a gas unit, but it might seem heavy to some people. Thanks to proper weight distribution (largely because of the huge 10 inch wheels) it is pretty easy to move around.

Overall this washer is pretty simple to operate and start up. The exhaust port is located in the upper right section which is also where the hose is, so I would advise to keep it as far away from the exhaust as possible. If it’s not, you may experience burning from the heat.

Additional Features

The Generac 6595 and 6596 both come with a spray gun as well as a 25-foot hose, which gives you plenty to play with when getting into those hard to reach places that need a good clean. To make the most out of the spray gun, this unit comes with four different nozzles.

The zero degree attachable nozzles comes in handy when you need to do some heavy duty cleaning on solid surfaces since it generates the most powerful jet of water. You also get 25 and 40 degree nozzles which are suitable for lighter cleaning tasks, as well as a soap nozzle.

While I’m on the subject of soap, the units have a 0.75-gallon capacity reservoir for detergent which should help you get rid of those stubborn stains.

The Verdict

If you want a gas powered unit, the Generac 6595 and 6596 pressure washers are one of the better options on the market. Free of any cables and wires apart from the hose, this pressure washer will provide you with better mobility and more power than the equivalent electric pressure washer. More power equals better results and efficiency.

The 6595 is pretty much the same as the 6596 except it delivers 2500 PSI. On the flip side, it is a bit cheaper, so if you are on a budget this one is also worth considering. You can get both the Generac 6596 and the 6595 on Amazon at a great price.
