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, unpainted surfaces or high reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and fragile surfaces
  • applying detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The Generac 6565 in use

The Generac 6565

Using a powerful 420 cc engine, its triplex pump delivers a pressure of up to 4200 PSI (roughly 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 16800 Cleaning Units.

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

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 1.5 gallon.

Design & Handling

The Generac 6565 is very mobile, due to its hand truck design and approximate dimensions of D34.5 x W28.3 x H42.5 in. The strong welded steel frame assures assembly longevity. The folding handle enhances its mobility, while allowing for a convenient storage.

The device weighs 146.5 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. The main contributor to its weight are its 420 cc Generac engine, the triplex pump and welded steel frame. However, its two 12" pneumatic wheels play an important part in its maneuvrability, as they allow for a smooth manipulation on the job.

Main Features

The Generac 6565 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The Generac 6565 is not equipped with a soap dilution mechanism, and thus, it is up to the user to ensure the detergent’s correct dilution ratio when using it. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: The included 50 ft ⌀3/8" high-pressure hose (4200 PSI rating) can be neatly stored on the unit when idle thanks to a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook. A rotating auxiliary side handle further improves both left-handed and right-handed users' comfort.
  • Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

The Generac 6565

  • Onboard storage: The Generac 6565 features a handy storage area, which allows you to neatly store nozzles and accessories and be always prepared by having everything needed at hand.
