Zoom on the Generac 6565

The Generac 6565 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • applying detergent and cleaning solutions

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Generac 6565 in use

The Generac 6565

Powered by an impressive 420 cc engine, its triplex pump can deliver a pressure of 4200 PSI (around 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). Combined, these values mean that the Generac 6565 has a cleaning power of 16800 Cleaning Units.

This gas-powered pressure washer’s Generac engine is started by a traditional pull-start mechanism.

Gasoline is stored in a fuel tank with a maximum capacity of 1.5 gallon.

Design & Handling

Thanks to its hand truck design and approximate dimensions of D34.5 x W28.3 x H42.5 in, the Generac 6565 offers great mobility. The robust and sturdy welded steel frame offers longevity to the assembly. The folding handle enhances its mobility, while allowing for a convenient storage.

At 146.5 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. Its 420 cc Generac engine, the triplex pump and welded steel frame are mainly responsible for its heavy weight. However, the device’s two 12" pneumatic wheels play a key role in its maneuverability, as they allow it to be manipulated smoothly.

Main Features

The Generac 6565's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. However, since the Generac 6565 does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: Using a set of convenient hooks, the included 50 ft ⌀3/8" high-pressure hose (4200 PSI rating) can be easily stored on the unit when it is not running.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand. A rotating auxiliary side handle further improves both left-handed and right-handed users' comfort.
  • Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

The Generac 6565

  • Onboard storage: With the Generac 6565's handy storage area, you’ll always have all the necessary nozzles and accessories at hand and thus, you’ll be fully prepared for any job.
  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation), a low oil protection and a thermal relief valve (which helps to prevent internal pump damage).
  • Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Generac 6565 comes with spray gun, oil, soap hose, wand and pressure hose.
  • Emissions: The Generac 6565 is NOT CARB-compliant. Therefore, it is not available in California for sale nor purchase.

The Generac 6565's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Generac 6565 compare to similarly priced pressure washers.

  • Reaching a 4200 PSI max pressure output, the Generac 6565 has an expected pressure value, compared to the other gas-powered units in the $1000 to $1200 price range. In case you are looking for a device with the highest possible power of its water stream, one of the top achievers in this price range is the Lifan LFQ4515E-CA with a PSI of 4500.
  • With a maximum GPM of 4 (gallons per minute), this washer belongs to the best in terms of water flow, in its respective price range.
  • With a rather impressive value of 16800 Cleaning Units (PSI x GPM), the 6565 has a higher cleaning efficiency compared to similarly priced devices. In case you are looking for the highest overall cleaning power, in this price range, one of the current champions is the Lifan LFQ4515E-CA and its 18000 Cleaning Units.
