Easy Assembly

Those new to pressure washing or even those familiar with it will appreciate just how quick and easy this pressure washer is to assemble without requiring any tools. Simply attach the handle, add gas and oil then attach the hoses then the machine is good to go.

Built for Practicality

For enhanced mobility over rough terrains, the Generac’s robust welded steel frame sits on two large 10″ never-flat wheels. The remarkably well balanced vertical design ensures the unit is easy to move around. A foot rest is situated at the front of the machine which helps you stabilize it as you start up the engine, avoiding any unwanted tip over occurring.

196cc Generac OHV Engine

To cope with the demands of tough applications on a regular basis, the machine is equipped with a high quality 196cc Generac OHV horizontal shaft engine which has a sizable fuel tank with a 3.8 quarts capacity. The recoil start allows for easy starting with a quick pull.

Axial Cam Pump with Easy-access Hose

The Generac 6596 is fitted with a reliable AR axial cam pump. The pump has been designed with the hose connections located at a reachable height above the wheels so the user doesn’t need to kneel when connecting hoses to the unit. This is especially good for people with back problems.

2,800 PSI Cleaning Pressure

For a residential-grade unit, this model has an excellent cleaning pressure rating of 2800 PSI with a 2.5 GPM water flow rate. This gives it enough cleaning power to take on the majority of demanding applications which call for high pressure.

Ergonomic Spray Gun

Generac’s ergonomically designed spray gun has a nicely cushioned grip handle for maximum user comfort during long uses. Additionally, its long easy pull trigger minimizes operator fatigue so you won’t get tired on the job.

A spray gun holder is situated on the frame in the centre to provide a handy and convenient place to hold the spray gun when it’s not in use.

On-board Detergent Tank

An onboard ¾ gallon tank lets you store detergent in the unit, giving you the option to use cleaning detergents when a task calls for it. The detergent is pumped straight through to the tip at a low pressure and injected into the water stream.

25′ PVC Hose

The 25 foot PVC hose provide ample length to reach wherever you need to clean. However, the hose itself isn’t one of the strong points of this machine. Since the hose is made from plastic and coated with PVC, it’s prone to breakage when it gets kinked so we recommend you replace it with a better hose when possible.

Quick-Click Nozzle Tips

Along with the spray gun itself, there are four quick click nozzle tips which specialize in providing the right amount of cleaning pressure for certain jobs. The nozzle tips include 0 degree, 25 degrees, 40 degrees plus a soap applicator tip when you need to use cleaning detergent.


Thanks to its vertical upright design, the Generac 6596 has quite a small footprint making it easy to store. It measures 40.3 inches in height, 23.3 inches in length and has a width of 16 inches. It weighs in at 61.5 pounds which makes it lighter than most similar machines in its class.

Pros and Cons


The Generac 6596 pressure washer is made in the USA and built with a rugged steel frame and high quality components. The stable compact, vertical design makes for easy transportation of the unit. Additionally, the overall design is well thought out which enables you to access the controls conveniently.

Its powerful OHV engine and pump deliver 2800 PSI which allows you to clean almost anything in a residential setting.

Highly affordable.


Poor quality hose. The included hose isn’t the best so we advocate investing in a better one asap.

It should be noted, this model isn’t CARB Compliant.

Final Thoughts

The Generac 6596 Pressure Washer has a fine blend of user-friendliness and high power, all at an affordable price. Its sturdy, robust design is reassuring for those in search of a long lasting machine.

It’s suitable for all general residential cleaning tasks like cleaning siding, decking and patio furniture as well as more heavy-duty applications like paint removal and getting rid of encrusted oil stains from surfaces.

While the hose isn’t up to par with the rest of the machines quality, it’s a relatively inexpensive part to replace so isn’t a major drawback.

This is an excellent medium-duty pressure washer which qualifies with a strong buy recommendation.
