Power

The Ryobi RY80940B in use

The Ryobi RY80940B

With a 187 cc (5.1 hp) engine, its aluminum axial cam pump delivers a pressure of 3100 PSI (roughly 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer), resulting in the Ryobi RY80940B's cleaning power of 7750 Cleaning Units.

The Honda GCV190 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

The fuel is stored in a tank, which can hold up to 0.25 gallon of gasoline, which provides an approximate runtime of 30 minutes.

Design & Handling

Thanks to its hand truck design, the Ryobi RY80940B offers great mobility. The robust steel tubing frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the RY80940B convenience of transport, while offering a comfortable grip.

Weighing 65 lbs, the unit is easy to maneuver by most people. A major component of its weight are its 187 cc Honda GCV190 engine and steel tubing frame. The RY80940B can still be easily manipulated and maneuvered, thanks to its two 12" wheels.

Main Features

Along with the Ryobi RY80940B itself, the package also includes a spray gun, a wand, a pressure hose, a 5-in-1 nozzle and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: A safe detergent storage is facilitated by a dedicated tank. The Ryobi RY80940B has an automatic soap dilution mechanism, which dilutes the detergent using a 20:1 ratio. Detergent is automatically added to the water when "soap" is selected on the 5-in-1 nozzle.
  • Pressure hose: Using a set of convenient hooks, the included 25 ft ⌀1/4" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzle: a 5-in-1 nozzle is included.

    Ryobi's 5-in-1 nozzle Ryobi's 5-in-1 nozzle offers five spray pattern settings (0°, 25°, 40°, short-range soap, long-range soap). Selection of a specific spray pattern is made by simply rotating the spray selector to the desired setting.

Other Features

  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation) and a thermal relief valve (which helps to prevent internal pump damage).
  • Accessories: The Ryobi RY80940B comes with an owner's manual (opens in a new tab) and some basic documentation to get you quickly started. On top of that, you also get oil, wand, spray gun, funnel and pressure hose.
  • Emissions: The Ryobi RY80940B is EPA-approved and CARB-compliant. Therefore, the sale and purchase of this pressure washer is permitted in all of the 50 states, including California.
